Abstract
Prilagodljiv nosač sa kliznom-rotacijskom bazom za mehaničko povezivanje zubno protetskog rada sa implantatom je izum iz područja dentalne implantologije. Izum pomoću jedinstvenog dizajna nosača jedinstvenim pristupom olakšava ispravljanje devijacija ili nagiba između implantata. Izum se sastoji od dva osnovna tijela (1) i (2) ili (3) te dva vijka (4) i (6) što sve zajedno čini izum cjelinom, a prednost izumu daju njegova dva osnovna sastojna dijela koja svojim spojem čine kliznu nezaključanu plohu. Ta ploha omogućuje nesmetanu rotaciju nosača (2) ili (3) oko svoje uzdužne osi neovisno o samom implantatu. Kombinacija specijalnog dizajna nosača i klizne plohe omogućuje njegovo namještanje u najoptimalniji položaj u korist nesmetanog nasjedanja dentalne konstrukcije. Izum je namijenjen povezivanju protetske konstrukcije sa bočnim horizontalnim vijkom (4) prolaskom kroz nosač. Kao posebnu mogućnost izum će omogućiti potpunu prilagodbu specijalno teškim situacijama u ustima pacijenata, suština je u dodatnoj promjeni položaja prolaza za bočni horizontalni vijak (4). Promjenu položaja prolaza za vijak će omogućiti pomično tijelo na vrhu nosača (5a).An adjustable sliding-rotary base for mechanically connecting dental prosthetics to an implant is an invention in the field of dental implantology. The invention by means of a unique carrier design by a unique approach facilitates the correction of deviations or tilts between implants. The invention consists of two basic bodies (1) and (2) or (3) and two screws (4) and (6), which together make the invention whole, and the invention gives priority to its two basic constituent parts, which by their compound are sliding unlocked surface. This surface allows the carrier (2) or (3) to rotate freely about its longitudinal axis independently of the implant itself. The combination of the special design of the bracket and the sliding surface allows it to be positioned in the most optimal position for the benefit of unobstructed seating of the dental structure. The invention is intended to connect a prosthetic structure to a lateral horizontal screw (4) passing through a support. As a special feature, the invention will allow complete adaptation to particularly difficult situations in the mouth of patients, the essence being the additional change of the passage position for the lateral horizontal screw (4). Changing the position of the bolt passage will allow the movable body at the top of the bracket (5a).

Područje tehnike na koje se izum odnosi Technical field to which the invention relates
(uz naznaku oznake po Međunarodnoj klasifikaciji patenata ako je podnositelju prijave poznata) (with an indication of the designation according to the International Classification of Patents if it is known to the applicant)
Prilagodljiv nosač koji se predstavlja kao izum dolazi iz područja dentalne medicine, konkretnije implantologije. The adjustable bracket that is presented as an invention comes from the field of dental medicine, more specifically implantology.
Služi povezivanju dentalnih implantata sa dentalnom protetikom, znači bitan je element prilikom ugrađivanja implantata u ljudsku čeljust a slični nosači se popularno u struci nazivaju „abutment“. It serves to connect dental implants with dental prosthetics, so it is an important element when installing implants in the human jaw, and similar supports are popularly called "abutment" in the profession.
U međunarodnoj klasifikaciji patenata slični izumi su kategorizirani oznakom: A61C8/00 In the international classification of patents, similar inventions are categorized under the code: A61C8/00
Tehnički problem Technical problem
(za čije se rješenje traži patentna zaštita) (for the solution of which patent protection is requested)
U dosadašnjoj praksi na području dentalne medicine konkretnije implantologije kao nedostatak pokazalo se nepostojanje univerzalnog sustava samo jednog tvornički pripremljenog nosača tj. jedinstvenog dizajna nosača sa kojim se jedinstvenim pristupom olakšava ispravljanje devijacija ili nagiba između implantata. Daljnji tehnički problem je nepostojanje mogućnosti individualizacije konvencionalnim materijalima (neplemenitim slitinama) tehnikom nadolijevanja s olakšanom mogućnošću povezivanja dentalne protetike sa nosačem pomoću bočnog vijka za privremene i trajne protetske konstrukcije. Protetske konstrukcije nije moguće povezivati pomoću bočnog vijka bez upotrebe alata i dodatnih priprema. Još jedan tehnički problem koji se ovim izumom rješava je nepostojanje univerzalnog rješenja prilikom korištenja CAD/CAM i kopirnih (pantograf) dentalnih sustava za izradu protetskih konstrukcija na implantatima a da se isti mogu povezati pomoću vijka. In the current practice in the field of dental medicine, more specifically implantology, the absence of a universal system of only one factory-prepared carrier, i.e. a unique design of the carrier, with which a unique approach facilitates the correction of deviations or tilts between implants, has been shown to be a disadvantage. A further technical problem is the absence of the possibility of individualization with conventional materials (non-precious alloys) using the pouring technique with the facilitated possibility of connecting dental prosthetics to the carrier using a lateral screw for temporary and permanent prosthetic constructions. Prosthetic structures cannot be connected using a lateral screw without the use of tools and additional preparations. Another technical problem that is solved by this invention is the lack of a universal solution when using CAD/CAM and copier (pantograph) dental systems to create prosthetic structures on implants that can be connected using screws.
Nadalje, otežana je mogućnost izrade ključa za pozicioniranje nosača, tj. prijenosa sa radnog modela u usta pacijenta. Sve navedeno je detaljno razrađeno i opisano u tekstu pod točkama niže. Furthermore, the possibility of making a key for positioning the bracket, i.e. transferring it from the working model to the patient's mouth, is difficult. All of the above is detailed and described in the text under the points below.
Stanje tehnike State of the art
(prikaz i analiza poznatih rješenja definiranog tehničkog problema) (presentation and analysis of known solutions to a defined technical problem)
Već je opće poznato da dentalni implantati služe za nadomjestak izgubljenih prirodnih zubi u gornjoj i donjoj čeljusti (lat. maxila i mandibula), a usađuju se u kost. Taj zahvat izvode isključivo oralnih kirurzi uz posebne namjenske alate na način da se odstrani zubno meso (gingiva) koje prekriva kost pacijenta. Zatim se izbuši mjesto u kosti gdje je predviđeno mjesto za implantat u koje se usađuje. Kost pacijenta je osnovna stvar za usađivanje implantata. Njezin položaj i količina, odnosno debljina određuju smjer ugrađivanja implantata. Kirurg koji ugrađuje implantate mora poštivati te elemente da bi u konačnici rad bio uspješan. Naime, zubni implantat ima vanjski navoj duž cijelog svog tijela, koje mu je pri završetku blago koničnog oblika. Taj se navoj urezuje u kost, što omogućuje njegovu primarnu stabilnost kao i oseointegraciju (srastanje s kosti), koja traje između 3 do 6 mjeseci. Tek nakon isteka tog perioda prilagodbe implantat je spreman za daljnju uporabu. It is already widely known that dental implants are used to replace lost natural teeth in the upper and lower jaw (lat. maxilla and mandible), and are implanted in the bone. This procedure is performed exclusively by oral surgeons with special dedicated tools in order to remove the gums (gingiva) covering the patient's bone. Then, a place is drilled in the bone where the intended place for the implant to be implanted is drilled. The patient's bone is the basic material for implant placement. Its position and amount, or thickness, determine the direction of implant placement. The surgeon who installs the implants must respect these elements in order for the work to be successful. Namely, the dental implant has an external thread along its entire body, which is slightly conical at the end. This thread is cut into the bone, which enables its primary stability as well as osseointegration (union with the bone), which lasts between 3 to 6 months. Only after the end of this adjustment period is the implant ready for further use.
Kako se taj implantat sada nalazi ispod vanjske razine zubnog mesa tj. u kosti pacijenta, potreban je dodatak koji služi kao nosač za protetsku rekonstrukciju, a obično se isti naziva „nadogradnja“ ili popularno „abutment“ (eng.). Implantat pri vrhu ima otvor tzv. „usta implantata“ koji je predviđen kao sjedište za nosač a povezuju se pomoću vijka, tj. navoja unutar samog implantata. Na ustima implantata obično se nalazi „ženski dio“ dok se na nosaču nalazi „muški dio“ (eng. internal / external connection), dok je to kod nekih sistema obrnuto. Do sada su se obično koristile originalne tvorničke komponente koje se razlikuju jedna od druge zbog svog individualnog pristupa izrade spojeva / dosjeda. As this implant is now located below the outer level of the gums, i.e. in the patient's bone, an attachment is needed that serves as a support for prosthetic reconstruction, and is usually called an "abutment" or, popularly, an "abutment". The implant has a so-called opening at the top. the "mouth of the implant" which is intended as a seat for the support and is connected by means of a screw, i.e. a thread inside the implant itself. There is usually a "female part" on the mouth of the implant, while there is a "male part" on the support (eng. internal / external connection), while in some systems it is the other way around. Until now, the original factory components were usually used, which differ from each other due to their individual approach to making joints / fits.
Svaka čeljust, svaki zub i stanje unutar usne šupljine su kod svakog pacijenta različiti pa je stoga i dentalna tehnika individualan i unikatan proizvod. Ne postoji serijsko rješenje u izradi protetskih radova na pacijentima. Sve navedeno vrijedi i za dentalnu implantologiju. Izrada i izvedba često znaju biti komplicirani i zahtjevni po pitanju izuma rješenja. Dentalni tehničari, osim što moraju biti izuzetno kreativni i često inovativni prilikom rješavanja i izrade, osuđeni su i na korištenje skupocjenih aparata, nabavu namjenskih alata za svakog odabranog proizvođača, stalne razvojne edukacije (obzirom da se ova grana rapidno širi i razvija), te dobro razumijevanje u materijale kao i njihovu obradu, što sve znatno poskupljuje kompletnu uslugu. Sve se više pacijenata odlučuje na implantološki rad obzirom da je njegova uspješnost 95%-100%. Početno su dentalni implantati bili ograničeni u svojoj primjeni, dok se danas primjenjuju u svim situacijama – od gubitka samo jednog pa sve do potpunog gubitka prirodnih zubi. Imaju svakako prednost ispred klasične izrade zubne protetike, brušenjem susjednih zuba i premoščivanjem. Each jaw, each tooth and the condition inside the oral cavity are different for each patient, so dental technology is an individual and unique product. There is no serial solution in the production of prosthetic works on patients. All of the above also applies to dental implantology. Design and implementation can often be complicated and demanding in terms of inventing solutions. Dental technicians, in addition to having to be extremely creative and often innovative when solving and creating, are also condemned to use expensive devices, purchase dedicated tools for each selected manufacturer, continuous development education (given that this branch is rapidly expanding and developing), and well understanding of the materials as well as their processing, all of which significantly increases the cost of the complete service. More and more patients decide on implantology work, given that its success rate is 95%-100%. Initially, dental implants were limited in their application, while today they are used in all situations – from the loss of just one to the complete loss of natural teeth. They certainly have an advantage over the classic production of dental prosthetics, by grinding adjacent teeth and bridging.
Ipak, kod ugradnje dva ili više implantata, što je čest slučaj, dolazi do pomicanja ili devijacija uzdužnih osi samih implantata, tj. nisu međusobno u pravilnom paralelnom položaju a potrebno ih je povezivati dentalnom protetskom konstrukcijom u jednu cjelinu. However, when installing two or more implants, which is often the case, there is movement or deviation of the longitudinal axes of the implants themselves, i.e. they are not in the correct parallel position with each other, and it is necessary to connect them with a dental prosthetic construction into one unit.
Dentalni tehničari, koji se služe nosačima kako bi mogli izraditi zubnu protetiku u smislu mostnih konstrukcija (engl. implant bridge), nailaze na disparalitet između tih nosača. Međutim, uz regularne uspravne moguće je koristiti zakrivljene nosače, koji ispravljaju gore navedene nepravilnosti a mogu biti pod kutom od 15°, 25° pa i 45° (u slučaju 45° uz korištenje posebnih dodataka) u odnosu na uzdužnu os implantata. Dosjed na muškom dijelu nosača koji se spaja na implantat je nepravilnog oblika, primjerice šesterokutan. Takve nepravilne strukture onemogućuju rotaciju oko svoje osi, ali znatno ograničavaju primjenu zakrivljenih nosača zbog ulaska dosjeda u implantat (kada su povezani u jednu cjelinu mostnom konstrukcijom potreban je idealan kut ulaska te konstrukcije u odnosu na položaj implantata). Dental technicians, who use supports to be able to create dental prosthetics in terms of bridge constructions (eng. implant bridge), encounter disparity between these supports. However, in addition to regular upright ones, it is possible to use curved supports, which correct the irregularities mentioned above and can be at an angle of 15°, 25° and even 45° (in the case of 45° with the use of special accessories) in relation to the longitudinal axis of the implant. The fit on the male part of the support that connects to the implant is irregularly shaped, for example hexagonal. Such irregular structures prevent rotation around their axis, but significantly limit the application of curved supports due to the entry of the abutments into the implant (when they are connected into one unit by a bridge structure, an ideal angle of entry of that structure in relation to the position of the implant is required).
Zbog navedene problematike, dentalni tehničari prisiljeni su prilikom izrade takvih mostnih konstrukcija mijenjati tvornički nosač , na način da ih obrađuju (bruse) pomoću raznih rotacijskih dentalnih alata u svrhu dobivanja optimalnog međusobnog paraliteta. Ta obrada smanjuje površinu na nosaču potrebnu za cementiranje gotovog protetskog rada pomoću specijalnih dentalnih cemenata (koji su inače osnova povezivanja), te njegovu čvrstoću a ujedno produžuje ukupno vrijeme izrade. Due to the aforementioned problem, dental technicians are forced to change the factory support when making such bridge structures, in such a way that they are processed (grinded) using various rotary dental tools in order to obtain optimal mutual parallelism. This treatment reduces the area on the support required for cementing the finished prosthetic work using special dental cements (which are normally the basis of bonding), as well as its strength, and at the same time prolongs the total production time.
Postoji i mogućnost individualizacije nosača pomoću tehnike nadolijevanja slitine na slitinu, gdje je baza nosača izrađena od slitine te se tehnikom modelacije i kasnije izlijevanja tijela nosača dobiva željeni oblik i položaj. Ta tehnika iziskuje duži period izrade, ali daje bolje rezultate u korist konačnog izgleda protetskog rada. Do sada je ova tehnika bila moguća jedino uz korištenje plemenite slitine što znatno poskupljuje cijenu izrade. There is also the possibility of individualizing the support using the alloy-to-alloy pouring technique, where the base of the support is made of alloy, and the desired shape and position is obtained by modeling and later casting the body of the support. This technique requires a longer production period, but gives better results in favor of the final appearance of the prosthetic work. Until now, this technique was only possible with the use of a precious alloy, which significantly increases the cost of production.
Devijaciju prilikom izrade mostnih konstrukcija moguće je ispraviti još i pomoću nosač-sustava koji omogućuju spajanje mostnih konstrukcija sa implantatom pomoću dva vijka i dva nosača po jednom implantatu. Prvi takav nosač koji svojim posebnim oblikom ispravlja devijaciju je već prethodno pričvršćen za implantat jednim vijkom. Drugi nosač zajedno s mostnom konstrukcijom je pričvršćen drugim vijkom za prvi nosač. Vijak pomoću kojeg se učvrstila mostna konstrukcija zajedno sa drugim nosačem za prvi nosač mora ostati dostupan kako bi se isti mogao dotegnuti, pa se stoga ostavlja otvor kroz protetsku konstrukciju sa gornje strane. Time se narušava estetika konačnog rada, jer stomatolozi iste zatvaraju pomoću kompozitnog materijala koji se koristi za zapunjavanje zubnog ispuna (plombi). Osim toga, kada nastane potreba bilo kakvog dorađivanja potrebno je ukloniti taj ispun kako bi se omogućio pristup vijku. Deviation during the fabrication of bridge structures can also be corrected by means of a support-system that enables the connection of bridge structures with the implant using two screws and two supports per implant. The first such support, which corrects the deviation with its special shape, is already pre-attached to the implant with one screw. The second support together with the bridge structure is attached to the first support with another screw. The screw that fixed the bridge structure together with the second support for the first support must remain accessible so that it can be tightened, and therefore an opening is left through the prosthetic structure from the upper side. This impairs the aesthetics of the final work, because dentists close them using a composite material used for dental fillings (fillings). In addition, when there is a need for any finishing, it is necessary to remove that filling to allow access to the screw.
Postoji način tvorničke izrade individualne protetske konstrukcije u Titan ili Cirkon-oksid materijalu, koji daje gotovo iste rezultate kao gore opisana tehnika, ali je nepopularan zbog svoje visoke cijene, vremenskog roka dostave gotove konstrukcije, obzirom da se izrađuju u inozemstvu. Uz to, primjena je moguća samo na određene implantološke sisteme pa je stoga ograničena. There is a method of factory production of an individual prosthetic structure in Titanium or Zirconium oxide material, which gives almost the same results as the technique described above, but is unpopular due to its high price, the time limit for delivery of the finished structure, considering that they are made abroad. In addition, the application is possible only on certain implantological systems and is therefore limited.
Odnedavno postoji rješenje koje također sa dva nosača povezuje više implantoloških sustava te omogućuje tehniku nadolijevanja slitine na slitinu (neplemenitih). To omogućuje ekonomičniju izradu protetskih konstrukcija koje se mogu izraditi u svakom standardno opremljenom dentalnom laboratoriju. Međutim, kod tog sustava ne postoji mogućnost povezivanja bočnim vijkom, već se protetska konstrukcija povezuje s implantatom kroz gornju plohu te opet dolazi do narušavanja estetike finalnog rada. Recently, there is a solution that also connects several implantology systems with two supports and enables the technique of pouring alloy on alloy (non-precious). This enables a more economical production of prosthetic constructions that can be made in any standard equipped dental laboratory. However, with this system, there is no possibility of connection with a lateral screw, but the prosthetic construction is connected to the implant through the upper surface, and again the aesthetics of the final work are disturbed.
Isto tako, moguće je povezivanje protetske konstrukcije sa nosačem pomoću vijka koji ulazi sa stražnje bočne strane. Međutim za korištenje takvog sustava vijka potreban je niz posebnih tvorničkih alata i dodataka, kao što su primjerice svrdla za bušenje i narezni alati. Ovdje se preporučuje rad sa plemenitim slitinama zbog njihove manje tvrdoće u odnosu na tvrdoću neplemenitih slitina zbog lakše uporabe svrdala za bušenje i nareznih alata. Dentalni tehničari moraju, pored svog praktičnog rada, još i pronalaziti idealnu točku za pozicioniranje tog vijka te izbušiti prolaz za isti kroz samu protetsku konstrukciju i nosač. Prilikom bušenja i korištenja nareznih alata često dolazi do pucanja samog alata. Dentalni tehničari često izbjegavaju takav sustav, zbog kompleksnosti izrade, ali i neisplativosti u slučaju loma pripadajućeg alata kao i mogućnosti oštećivanja osnovne dentalne aparature (mikro-motor). Likewise, it is possible to connect the prosthetic structure to the support using a screw that enters from the back side. However, using such a screw system requires a number of special factory tools and accessories, such as drill bits and tapping tools. Here, it is recommended to work with precious alloys due to their lower hardness compared to the hardness of non-precious alloys due to the easier use of drill bits and tapping tools. Dental technicians, in addition to their practical work, also have to find the ideal point for positioning that screw and drill a passage for it through the prosthetic construction itself and the support. When drilling and using threaded tools, the tool itself often breaks. Dental technicians often avoid such a system, due to the complexity of manufacturing, but also the unprofitability in case of breakage of the associated tool, as well as the possibility of damaging the basic dental apparatus (micro-motor).
Dodatno je potrebno izdvojiti da se u dentalnoj tehnici sve više koriste CAD/CAM sustavi koji su namijenjeni izradi konstrukcija od Cirkon-Oksida i Titan materijala. Da bi se koristili za izradu mostnih konstrukcija na implantatima potrebno je koristiti posebne nosače (obično su od Titana, tzv. „linkove“) namijenjene u tu svrhu, jer ti sustavi koriste sustav skeniranja radnog modela. In addition, it is necessary to distinguish that CAD/CAM systems are increasingly being used in dental technology, which are intended for the production of structures from Zircon-Oxide and Titanium materials. In order to use them for the creation of bridge structures on implants, it is necessary to use special supports (usually made of Titan, so-called "links") intended for this purpose, because these systems use the scanning system of the working model.
Pri tome često nastane problem kod spajanja tih nosač-linkova sa konstrukcijama, posebice kod Titana, obzirom da je postupak spajanja Titana sa Titanom moguće postići jedino pomoću laserskog uređaja tehnikom zavarivanja koji ne spada u standardnu opremu dentalnih laboratorija. Spajanje Cirkon-Oksida sa Titanom zahtjeva uporabu posebnih dentalnih cemenata koji kasnije, ukoliko je potrebno izvršiti izmjenu rada (što je u praksi vrlo čest slučaj), izgori zbog visokih temperatura u keramičkoj peči pa je stoga postupak cementiranja potrebno ponoviti nakon izvršenja izmjene, a stvaran problem je što ne postoji način privremenog učvršćivanja konstrukcije sa nosačem do stvarnog završetka konačnog rada. In this, a problem often arises when joining these carrier-links with structures, especially with Titan, since the process of joining Titan with Titan can only be achieved using a laser device using the welding technique, which is not part of the standard equipment of dental laboratories. Joining Zircon-Oxide with Titanium requires the use of special dental cements, which later, if it is necessary to change the work (which is a very common case in practice), burn out due to the high temperatures in the ceramic furnace, and therefore the cementing process must be repeated after the change, and real the problem is that there is no way to temporarily fix the structure with the support until the actual completion of the final work.
Implantati smješteni u organizmu pacijenta izrađuju se od bio-kompatibilnih materijala (Titan i Cirkon-oksid) kako ne bi izazvali neželjene reakcije organizma sa stranim tijelom (npr. odbacivanje, alergijske reakcije i sl.) dok nosači mogu uz već spomenute materijale biti izrađeni još od plemenitih slitina (zlato, paladij), neplemenitih slitina (kobalt-krom), keramičkih i kompozitnih materijala. Sam odabir materijala ovisi o odabiru materijala od kojeg će se izrađivati dentalna protetika ovisno o svrsi, potrebama estetike, ali i lokaciji upotrebe u usnoj šupljini. Implants placed in the patient's body are made of bio-compatible materials (Titanium and Zirconium oxide) so as not to cause unwanted reactions of the body with a foreign body (e.g. rejection, allergic reactions, etc.), while the supports can be made with the already mentioned materials from precious alloys (gold, palladium), non-precious alloys (cobalt-chromium), ceramic and composite materials. The choice of material itself depends on the choice of material from which dental prosthetics will be made depending on the purpose, the needs of aesthetics, but also the location of use in the oral cavity.
Karakteristika većine ovih sustava je da se oni izrađuju, odnosno individualiziraju u dentalnim laboratorijima, tj. njihovu izmjenu a samim time kasniju izradu dentalne konstrukcije izrađuju dentalni tehničari. Kako bi taj rad u cijelosti i zadržanoj poziciji stigao u usta pacijenta a to rade isključivo stomatolozi ili oralni kirurzi, potrebno je u većini slučajeva izraditi tzv. "ključ“. Bitno je da svaki nosač koji dentalni tehničar na svom radnom modelu postavi u jedan određen položaj, da se isti ti nosači u istim položajima prenesu u usta pacijenta tj. da zadrže taj isti položaj. Taj prijenos se u etapama izrade dentalne protetske konstrukcije ponavlja nekoliko puta do zaključenja same izrade. Ključ se obično izrađuje na radnom modelu dentalnog tehničara po nosačima nakon preoblikovanja ili individualizacije od akrilnog materijala ili tehnikom modelacije pa izlijevanja neplemenitim slitinama. Kako obično nedostaju retencijski elementi za koje će se učvrstiti ključ za nosače, taj ključ ponekad predstavlja težu etapu izrade i zna znatno produžiti vrijeme pozicioniranja nosača u usta pacijenta. Pacijenti koji moraju prolaziti te etape zajedno sa stomatologom, odnosno kirurgom i dentalnim tehničarom, znaju biti znatno izmoreni zbog produženog potrebnog vremena za prijenos situacije sa radnog modela u njegova usta. Iz tog razloga potrebno je skratiti to vrijeme i olakšati način prijenosa dentalne protetske konstrukcije. The characteristic of most of these systems is that they are made, that is, individualized in dental laboratories, i.e. their modification and thus the subsequent production of the dental structure is made by dental technicians. In order for this work to reach the patient's mouth in its entirety and in a retained position, which is done exclusively by dentists or oral surgeons, it is necessary in most cases to create the so-called "key". It is important that every bracket that the dental technician places on his working model in one specific position, that these same brackets are transferred to the patient's mouth in the same positions, i.e. that they keep that same position. construction is repeated several times until the conclusion of the production itself. The key is usually made on the dental technician's working model by brackets after reshaping or individualization from acrylic material or by modeling technique and then casting with non-precious alloys. As the retention elements to which the key will be attached to the brackets are usually missing, this the key sometimes represents a more difficult stage of production and can significantly increase the time it takes to position the bracket in the patient's mouth. Patients who have to go through these stages together with the dentist, that is, the surgeon and the dental technician, can be significantly tired due to the extended time required to transfer the situation from the working model to his mouth For this reason, it is necessary to shorten that time and facilitate the method of transfer of the dental prosthetic construction.
Izlaganje biti (suštine) izuma Presentation of the essence of the invention
(tako da se tehnički problem i njegovo rješenje mogu razumjeti te navođenje tehničke novosti izuma u odnosu na prethodno stanje tehnike) (so that the technical problem and its solution can be understood, as well as stating the technical novelty of the invention in relation to the previous state of the art)
Izum se sastoji od dva osnovna tijela te dva vijka što sve zajedno čini jedinstveni proizvod u svojoj cjelini. Već je prethodno opisano da tehnika cementiranjem zahtjeva posebnu pripremu nosača kroz njegovu obradu. Izum će omogućiti svojim specijalnim dizajnom nosača povoljan kut u odnosu na uzdužnu os implantata te samim time skratiti postupak, jer neće biti potrebna nikakva dodatna obrada ili izmjena oblika nosača. Prednost pred tvorničkim nosačima izumu daju njegova dva sastojna dijela koja svojim spojem čine kliznu nezaključanu plohu. Ta ploha omogućuje nesmetanu rotaciju nosača oko svoje uzdužne osi neovisno o samom implantatu. Kombinacija tog specijalnog dizajna nosača i klizne plohe omogućuje njegovo namještanje u najoptimalniji položaj u korist nesmetanog nasjedanja dentalne konstrukcije. The invention consists of two basic bodies and two screws, which together form a unique product as a whole. It has already been described previously that the cementing technique requires a special preparation of the support through its processing. The invention will enable, with its special design of the support, a favorable angle in relation to the longitudinal axis of the implant, thus shortening the procedure, because no additional processing or modification of the shape of the support will be required. The advantage over factory supports is given to the invention by its two component parts, which form a non-locking sliding surface. This surface enables the support to rotate freely around its longitudinal axis, independent of the implant itself. The combination of this special design of the support and the sliding surface allows it to be adjusted in the most optimal position for the benefit of the unhindered seating of the dental structure.
Izum je naime kao takav namijenjen povezivanju protetske konstrukcije sa vijkom. Za razliku od dosadašnjih sustava, vijak unutar izuma neće prolaziti kroz protetsku konstrukciju s gornje strane na način da time narušava estetiku finalnog rada ili bočne strane uz korištenje niza posebnih namjenskih alata i dodataka uz obavezno korištenje plemenitih slitina. Njegova prednost leži u činjenici da će tvornička priprema nosača biti u potpunosti prilagođena jednostavnijoj upotrebi bočnog vijka. Povezivati će protetsku konstrukciju u dvije točke prolaskom kroz cijeli nosač. Time se bitno olakšava mehanički pristup povezivanja protetske konstrukcije sa nosačem, s time da će sam vijak već u etapi modelacije protetske konstrukcije omogućiti pozicioniranje idealnog sjedišta u protetskoj konstrukciji. Nosač zbog svog specijalnog dizajna i klizne plohe koje tvore njegova dva tijela omogućuje namještanje u najoptimalniji položaj, bez prethodne pripreme u smislu izuma optimalne točke za bušenje, pa time i korištenje niza alata i dodataka neće biti potrebno. Dentalni tehničari će nakon što odrede idealni položaj nosača kroz već prethodno tvornički pripremljen prolaz, provući vijak te zatezivanjem spojiti protetsku konstrukciju s nosačem a samim time na protetskoj konstrukciji neće biti potrebno tražiti idealno mjesto te je bušiti. The invention is intended as such to connect the prosthetic structure with the screw. Unlike previous systems, the screw inside the invention will not pass through the prosthetic construction from the upper side in such a way as to impair the aesthetics of the final work or the side, with the use of a series of special dedicated tools and accessories with the mandatory use of precious alloys. Its advantage lies in the fact that the factory preparation of the support will be fully adapted to the simpler use of the side screw. It will connect the prosthetic construction in two points by passing through the entire support. This significantly facilitates the mechanical approach of connecting the prosthetic structure to the support, with the fact that the screw itself will enable the positioning of the ideal seat in the prosthetic structure already at the stage of modeling the prosthetic structure. Due to its special design and the sliding surface formed by its two bodies, the support allows it to be adjusted to the most optimal position, without prior preparation in terms of finding the optimal point for drilling, so the use of a number of tools and accessories will not be necessary. Dental technicians, after determining the ideal position of the support through a previously prepared passage in the factory, will insert the screw and tighten it to connect the prosthetic structure to the support, and therefore it will not be necessary to search for the ideal place on the prosthetic structure and drill it.
Kao posebnu mogućnost uz sve to, izum će omogućiti potpunu prilagodbu specijalno teškim ali rijetkim situacijama u ustima pacijenata. Tehnikom nadolijevanja slitinom na slitinu i korištenje neplemenitih slitina za izradu nosača a okarakterizirano je kada situacija zahtjeva upotrebu dodatnog nosača pri kutovima većim od 25°. U toj tehničkoj karakteristici suština je u dodatnoj promjeni položaja prolaza za bočni vijak, ali uz zadržavanje svih svojstava tvorničke pripreme za prolaz vijka te specijalnog dizajna nosača. Promjenu položaja prolaza za vijak će omogućiti pomično tijelo na vrhu nosača. Ta tehnička karakteristika izumu omogućuje korištenje svog nosača kao osnovu bez upotrebe dodatnog nosača. As a special possibility in addition to all that, the invention will enable complete adaptation to especially difficult but rare situations in the mouths of patients. The technique of pouring alloy on alloy and the use of non-precious alloys for the manufacture of supports is characterized when the situation requires the use of an additional support at angles greater than 25°. The essence of this technical characteristic is the additional change in the position of the passage for the side screw, but while maintaining all the features of the factory preparation for the passage of the screw and the special design of the support. Changing the position of the passage for the screw will be made possible by a movable body on top of the support. This technical characteristic allows the invention to use its support as a base without the use of an additional support.
Pored svega gore navedenog, zbog svojih manjih dimenzija u odnosu na postojeće, što omogućuje njegov specijalni dizajn nosača, izum omogućava dentalnim tehničarima znatno bolje planiranje protetskog rada. U susret ide i pacijentima i stomatolozima obzirom da je vijak smješten nisko uz samu gingivu (zubno meso) pacijenta sa stražnje nevidljive strane, pa time održava estetiku zadovoljavajućom za pacijenta te nesmetan pristup stomatologu. In addition to all of the above, due to its smaller dimensions compared to existing ones, which is made possible by its special carrier design, the invention enables dental technicians to plan prosthetic work much better. It meets the needs of both patients and dentists, since the screw is placed low against the patient's gingiva (tooth pulp) from the rear, invisible side, thus maintaining satisfactory aesthetics for the patient and unobstructed access to the dentist.
Prednost koju izum donosi je neograničenost u smislu kombiniranja materijala za izradu protetske konstrukcije. Naime, njegove male dimenzije, specijalni dizajn i bočni vijak omogućuju izradu protetske konstrukcije konvencionalnim tehnikama, kao što su Kobalt-Krom ili Titan, a isto tako omogućavaju pojednostavljenu izradu konstrukcije Cirkon-Oksidom u CAD/CAM sustavima. CAD/CAM sustavi koji se koriste u dentalne svrhe sadrže skenere radnih modela i jedinicu za glodanje materijala. Dizajn nosača omogućava bolju iskoristivost skenera radnog modela a samim time olakšanu izradu protetske konstrukcije glodanjem, te neće biti potrebe za korištenjem dodatnog nosača-linka za povezivanje protetske konstrukcije sa implantatom. The advantage that the invention brings is unlimited in terms of combining materials for the production of prosthetic construction. Namely, its small dimensions, special design and side screw enable the production of prosthetic construction using conventional techniques, such as Cobalt-Chrome or Titanium, and also enable simplified production of the construction with Zircon-Oxide in CAD/CAM systems. CAD/CAM systems used for dental purposes include working model scanners and a material milling unit. The design of the support enables better use of the scanner of the working model and thus facilitates the production of the prosthetic structure by milling, and there will be no need to use an additional support-link to connect the prosthetic structure to the implant.
Pored uloge učvršćivanja protetskih konstrukcija bočni vijak kao sastavni dio izuma, ima isto tako ulogu privremenog učvršćivanja protetske konstrukcije do njenog stvarnog završetka kao i ulogu učvršćivanja ključa za nosač. Ključ se sada može bez problema izraditi samo od akrilnog materijala te istim načinom kao protetska konstrukcija pričvrstiti za nosač bočnim vijkom a da ključ prilikom prijenosa ostaje pričvršćen za nosač. Takva metoda bitno krati vrijeme koje je potrebno za prijenos nosača sa radnog modela u usta. In addition to the role of securing prosthetic structures, the lateral screw as an integral part of the invention also has the role of temporarily securing the prosthetic structure until its actual completion, as well as the role of securing the key to the bracket. The key can now be easily made from acrylic material only and attached to the bracket with a side screw in the same way as the prosthetic construction, while the key remains attached to the bracket during transport. This method significantly shortens the time needed to transfer the carrier from the working model to the mouth.
Zbog široke potrebe načina izvedbe protetskih konstrukcija koje su kroz godine upotrebe implantata dosegle nekoliko opće prihvaćenih načina izrade protetskih konstrukcija na implantatima, bitno je za napomenuti da izum otvara mogućnost odabira korištenja ili nekorištenja bočnog vijka prilikom korištenja tehnike nadolijevanja slitine na slitinu tj. omogućuje samom izumu korištenje glavnog vijka kao jedinu poveznicu s implantatom. Jedan od načina ostvarivanja tehničkih karakteristika ovog izuma, je prednost ove tehnike nadolijevanjem slitine na slitinu. Izrada tzv. prečke će bez korištenja dodatnog nosača zadovoljiti potrebe povezivanja dentalne protetike sa implantatima ovim načinom izrade. Dentalni tehničar može nosač prilagoditi situaciji u ustima pacijenta a zadržati one tehničke karakteristike izuma koje mu omogućavaju namještanje u idealan položaj i nesmetano nasjedanje protetske konstrukcije zajedno sa nosačem pomoću klizne plohe. Due to the wide need for methods of performing prosthetic constructions, which through the years of implant use have reached several generally accepted methods of making prosthetic constructions on implants, it is important to note that the invention opens up the possibility of choosing to use or not use a side screw when using the alloy-to-alloy pouring technique, i.e. it enables the invention itself using the main screw as the only connection to the implant. One of the ways to realize the technical characteristics of this invention is the advantage of this technique by pouring alloy on alloy. Making the so-called bars will meet the needs of connecting dental prosthetics with implants without the use of an additional support with this manufacturing method. The dental technician can adapt the carrier to the situation in the patient's mouth and retain those technical characteristics of the invention that enable it to be adjusted in the ideal position and the prosthetic structure to fit smoothly together with the carrier using a sliding surface.

Detaljan opis najmanje jednog od načina ostvarivanja izuma A detailed description of at least one way of realizing the invention
Da se prava već zaštićenih sličnih proizvoda tj. njihovih sastavnih dijelova ne bi povrijedila izum koristi poseban uložak (1) koji će osim povezivanja i poboljšanja stabilnosti imati i funkciju klizanja (tvoreći tako potpuno novu zasebnu jedinicu namijenjenu isključivo ovom sustavu tj. tijelu nosača a dolaziti će u paru kao jedna jedinica) koja omogućuje pozicioniranje tijela nosača (2) ili (3) u željeni tj. najbolji položaj koji kasnije omogućuje lakšu i bolju izradu zubne protetske konstrukcije i to na više načina: In order not to infringe the rights of already protected similar products, i.e. their constituent parts, the invention uses a special insert (1) which, in addition to connecting and improving stability, will also have a sliding function (thus creating a completely new separate unit intended exclusively for this system, i.e. the body of the carrier and coming will be in pairs as one unit) which enables the positioning of the carrier body (2) or (3) in the desired, i.e. the best position, which later enables easier and better fabrication of the dental prosthetic structure in several ways:
Uložak (1) će pratiti konture i izgled samog dosjeda (1a) odgovarajućeg implantata (0), imat će funkciju podložne pločice a položaj ugradnje mu je po uzdužnoj osi implantata. Cjelovitu prilagodljivost izuma omogućava gornja ploha uloška tj. klizna ploha uloška (1b) koja ima specifičan oblik i tvorit će univerzalan spoj sa svim kasnijim potrebama izvedbe protetske konstrukcije tj. standardizaciju pomoću korištenja izuma. The insert (1) will follow the contours and appearance of the fit (1a) of the corresponding implant (0), will have the function of a backing plate, and its installation position is along the longitudinal axis of the implant. The complete adaptability of the invention is made possible by the upper surface of the insole, i.e. the sliding surface of the insole (1b), which has a specific shape and will form a universal joint with all subsequent needs for the performance of the prosthetic construction, i.e. standardization through the use of the invention.
Uložak (1) uz funkcije povezivanja, poboljšanja stabilnosti i funkcije klizanja će biti nositelj dosjeda (1a) koji će biti prilagođen originalnim implantatima (0) pa stoga ima ulogu univerzalnog konvertera. Svojom cijelom dužinom precizno nasjeda u implantat (0) a vidljiv će biti isključivo dio na kojem se nalazi klizna ploha uloška (1b) koja viri iz implantata (0), tj. usta implantata (0a). The insole (1) in addition to the functions of connection, improvement of stability and sliding function will be the carrier of the dosage (1a) which will be adapted to the original implants (0) and therefore has the role of a universal converter. It fits precisely into the implant (0) along its entire length, and only the part where the sliding surface of the insert (1b) is located that protrudes from the implant (0), i.e. the mouth of the implant (0a), will be visible.
Klizna ploha uloška (1b) u presjeku izgleda kao da je sa svake strane „rebro“ ispupčenog oblika a u svom punom obliku tvori jednu ispupčenu pravilnu kružnicu koja ima funkciju pozicioniranja tj. sigurnog i preciznog dosjeda tijela nosača (2) ili (3). Nasjedne plohe ispupčene kružnice oblikovane su pod kutom od 45° u odnosu na uzdužnu os ugradnje što omogućava olakšano nasjedanje tijela nosača (2) ili (3) u svim situacijama izrade mostne protetske konstrukcije. Zbog potrebe izrade dentalne rekonstrukcije narušene funkcije zubne čeljusti gubitkom jednog zuba, klizna ploha uloška (1b) će na svojem najispupčenijem dijelu imati urezano 12 „zubića“ koje su zapravo sjedište za osigurač (1c) a koji je u ovakvim slučajevima potreban za zaključavanje klizne plohe (rotacije oko svoje osi prilikom djelovanja žvačnih sila). Osigurač (2c) ili (3c) će biti opisan kao sastavni dio u detaljnom opisu tijela nosača (2) ili (3). Samim time, spajaju se dva načina „engaging i non-engaging“ (zaključano i nezaključano) u jedan jedinstveni sustav. Dentalni tehničari će sa standardnim rotacijskim obradnim alatima vrlo jednostavnom tehnikom pretvoriti zaključani u nezaključani sustav. In section, the sliding surface of the insert (1b) looks like it has a bulging "rib" on each side, and in its full form it forms a bulging, regular circle that has the function of positioning, i.e. safe and precise fit of the body of the carrier (2) or (3). The seating surfaces of the bulging circle are shaped at an angle of 45° in relation to the longitudinal axis of the installation, which enables easier seating of the body of the support (2) or (3) in all situations of making the prosthetic bridge structure. Due to the need to make a dental reconstruction of the impaired function of the dental jaw due to the loss of one tooth, the sliding surface of the insert (1b) will have 12 "teeth" engraved on its most convex part, which are actually the seat for the fuse (1c), which in such cases is needed to lock the sliding surface (rotation around its axis during the action of masticatory forces). The fuse (2c) or (3c) will be described as an integral part in the detailed description of the carrier body (2) or (3). Thus, the two modes "engaging and non-engaging" (locked and unlocked) are combined into one unique system. Dental technicians will convert a locked system into an unlocked system with a very simple technique using standard rotary processing tools.
Cjelovitost izuma čini jedinstveni dizajn tijela nosača (2) a čija će klizna ploha tijela nosača (2b) biti univerzalna standardizirana poveznica sa različitim vrstama uložaka te čini odgovarajući „ženski“ dio klizne plohe uloška (1b) tj. tvori pravilnu urezanu kružnicu koja u svom presjeku izgleda kao par urezanih rebara, s time da su plohe kružnice s jedne i druge strane pod kutom od 45°. The integrity of the invention is made by the unique design of the support body (2), whose sliding surface of the support body (2b) will be a universal standardized connection with different types of inserts and forms the corresponding "female" part of the sliding surface of the insert (1b), i.e. it forms a regular incised circle which in its in cross-section it looks like a pair of incised ribs, with the flat circles on one side and the other at an angle of 45°.
Sa svojim nasjedanjem na uložak (1), tijelo nosača (2) u cijelosti pokriva kliznu plohu uloška (1b) i time dolazi do ruba usta implantata (0a). Klizna ploha tijela nosača (2b) ovisno o potrebi (stručno: „single“ ili „bridge“ tj. jedan zub ili mostna konstrukcija) u svojoj funkciji može biti zaključana ili nezaključana ploha. With its fit on the inlay (1), the body of the support (2) completely covers the sliding surface of the inlay (1b) and thus reaches the edge of the implant mouth (0a). Depending on the need, the sliding surface of the carrier body (2b) (technically: "single" or "bridge", i.e. one tooth or bridge structure) can be a locked or unlocked surface in its function.
Osigurač (2c) je ispupčeni poprečni dio u kliznoj plohi tijela nosača (2b) i odgovarajući je ''muški'' dio urezanom dijelu na kliznoj plohi uloška (1c). Ujedno omogućuje namještanje u isti željeni položaj koji je dentalni tehničar prethodno odredio, te je po tom određenom položaju tijela nosača (2) napravio protetski rad, a na raspolaganju mu stoje 12 različitih položaja što omogućuje bolju iskoristivost posebnog dizajna tijela nosača (2). The fuse (2c) is a protruding transverse part in the sliding surface of the carrier body (2b) and is a corresponding "male" part to the slotted part on the sliding surface of the cartridge (1c). At the same time, it enables adjustment to the same desired position that the dental technician previously determined, and he made prosthetic work according to that specific position of the body of the carrier (2), and 12 different positions are available to him, which enables better utilization of the special design of the body of the carrier (2).
Na spomen glavnog okomitog vijka (6) jasno je da taj vijak isto tako prolazi uzdužnom osi tijela nosača (2), u čijoj sredini se nalazi cilindrični prolaz (2d) za vijak tako tvoreći otvore sa jedne i druge strane. Kako bi bilo moguće dotezanje tijela nosača (2) pomoću glavnog okomitog vijka (6), unutar cilindričnog prolaza (2d) se nalazi suženje tj. prsten (2a) koji je koničnog oblika s time da je prolaz iznad širi dok je prolaz ispod uži. Taj prsten (2a), svojim koničnim oblikom pored dobivanja bolje sile dotezanja ima i ulogu čuvanja prostora tj. ojačavanja stijenki klizne plohe tijela nosača (2b). At the mention of the main vertical screw (6), it is clear that this screw also passes through the longitudinal axis of the support body (2), in the middle of which there is a cylindrical passage (2d) for the screw, thus forming openings on one and the other side. In order to make it possible to tighten the body of the support (2) using the main vertical screw (6), inside the cylindrical passage (2d) there is a constriction, i.e. a ring (2a) which is conical in shape, with the passage above being wider while the passage below is narrower. This ring (2a), with its conical shape, in addition to obtaining a better tightening force, also has the role of saving space, i.e. strengthening the walls of the sliding surface of the carrier body (2b).
Bit tijela nosača (2) je u njegovom specifičnom dizajnu, koji dolazi do izražaja kroz kliznu plohu tijela nosača (2b) jer omogućuje dentalnom tehničaru da isti zaokrene do željenog položaja. Tijelo je oblikovano na način da u svojoj prednjoj strani tijela nosača (2e), prema vidljivoj strani pacijenta (obrazu), ima vrlo povoljan kut od 35° na uzdužnu os, dok bočne strane tijela nosača (2f) ostvaruju kut od 20°. Stražnja strana tijela nosača (2g) ima kut od 5° na uzdužnu os te tako tvore krnji stožac. The essence of the support body (2) is in its specific design, which is expressed through the sliding surface of the support body (2b) because it allows the dental technician to turn it to the desired position. The body is shaped in such a way that in its front side of the carrier body (2e), towards the visible side of the patient (cheek), it has a very favorable angle of 35° to the longitudinal axis, while the side sides of the carrier body (2f) achieve an angle of 20°. The rear side of the support body (2g) has an angle of 5° to the longitudinal axis, thus forming a truncated cone.
Na tijelu će biti prolaz za bočni horizontalni vijak (2h) koji je u horizontalnom položaju u odnosu na uzdužnu os. Iz gornje perspektive tijela nosača (2) vidi se da je položaj tog prolaza (2h) između plohe prednje strane (2e) i plohe stražnje strane (2g), tvoreći tako horizontalni prolaz kroz tijelo nosača (2). Visina, tj. položaj tog prolaza (2h) je pozicioniran na način da svojim promjerom ne ugrozi strukturalnu čvrstoću stijenki bočnih strana (2f) te samim time ukupnu čvrstoću tijela nosača (2). Unutar prolaza za bočni horizontalni vijak (2h) nalazi se navoj u prolazu za bočni horizontalni vijak (2i). On the body there will be a passage for the lateral horizontal screw (2h) which is in a horizontal position in relation to the longitudinal axis. From the top perspective of the support body (2), it can be seen that the position of this passage (2h) is between the front surface (2e) and the back surface (2g), thus forming a horizontal passage through the support body (2). The height, i.e. the position of this passage (2h) is positioned in such a way that its diameter does not threaten the structural strength of the side walls (2f) and thus the overall strength of the support body (2). Inside the passage for the side horizontal screw (2h) there is a thread in the passage for the side horizontal screw (2i).
Prsten graničnik (2j) koji se nalazi na najširem donjem dijelu tijela nosača (2) služi kao graničnik za sprječavanje nabijanje protetske konstrukcije uslijed aksijalnog opterećenja (uzdužne osi) te služi kao polazišna točka iz gingive (zubnog mesa) prilikom planiranja protetske konstrukcije. The ring stop (2j) located on the widest lower part of the body of the support (2) serves as a stop to prevent the prosthetic structure from compacting due to axial load (longitudinal axis) and serves as a starting point from the gingiva (gum) when planning the prosthetic structure.
Isključivo za posebne situacije tj. kod potrebe za individualizacijom tvornički prilagođeno tijelo nosača (3) izgledat će umanjeno, te će biti prilagođeno za tehniku nadolijevanja i prianjanje tj. spajanje objekata sa elementima kemijske i mehaničke retencije (3e). Klizna ploha tijela nosača kao i osigurač su sastavni dijelovi ovog tijela nosača (3) te su identičnog opisa kao kod već gore spomenutog tijela nosača (2) pa se s time neće ponovo opisivati. Ostatak tijela, koje se sada zove tijelo za lijevanje (5) svojim oblikom nastavlja svoj specifičan dizajn sa urezanim sjedištem za klip (5b), te kao sastavnim djelom klipom (5a). Exclusively for special situations, i.e. when there is a need for individualization, the factory-adjusted support body (3) will look reduced, and will be adapted for the filling and adhesion technique, i.e. connecting objects with elements of chemical and mechanical retention (3e). The sliding surface of the carrier body as well as the fuse are integral parts of this carrier body (3) and are of the same description as the aforementioned carrier body (2), so they will not be described again. The rest of the body, which is now called the casting body (5), continues its specific design with a slotted seat for the piston (5b), and as an integral part the piston (5a).
Strane tijela koje svojim oblikom tvore specijalan dizajn na način da je gornja strana tijela nosača (5h) vertikalno ravna u odnosu na uzdužnu os, dok je prednja strana tijela nosača (5e) pod kutom od 35° na uzdužnu os. Bočne strane tijela nosača (5f) ostvaruju kut od 20°, dok je stražnja strana tijela nosača (5g) pod kutom od 0° i sadrži urezano sjedište za klip (5b) koje polazi od vrha plohe (5h), te ulazi u prsten graničnik (5j). Kao dodatak otvara se mogućnost promjene smjera i položaja prolaza za bočni horizontalni vijak (2h) koji je sastavni dio klipa (5a). Klip (5a) nasjeda u urezano sjedište za klip (5b) u tijelu za lijevanje (5) koji mu omogućuje dodatno okretanje, promjenu visine i nagiba u odnosu na uzdužnu os. Na spomen glavnog okomitog vijka (6) jasno je da taj vijak isto tako prolazi uzdužnom osi tijela za lijevanje (5), u čijoj sredini se nalazi cilindrični prolaz za vijak (5d) tako tvoreći otvore sa jedne i druge stane. Side bodies that form a special design in such a way that the upper side of the support body (5h) is vertically straight in relation to the longitudinal axis, while the front side of the support body (5e) is at an angle of 35° to the longitudinal axis. The sides of the support body (5f) form an angle of 20°, while the back side of the support body (5g) is at an angle of 0° and contains a slotted seat for the piston (5b) that starts from the top of the surface (5h) and enters the stop ring (5j). As an addition, it is possible to change the direction and position of the passage for the lateral horizontal screw (2h), which is an integral part of the piston (5a). The piston (5a) fits into a slotted piston seat (5b) in the casting body (5) which allows it to rotate additionally, change height and tilt in relation to the longitudinal axis. At the mention of the main vertical screw (6), it is clear that this screw also passes along the longitudinal axis of the casting body (5), in the middle of which there is a cylindrical passage for the screw (5d), thus forming openings from one side and the other.
Obzirom da je od važnosti za opis tehničkog ostvarivanja načina izuma, niže će se spomenuti materijale od kojih će se izrađivati tijelo za lijevanje (5): Given that it is important for the description of the technical implementation of the invention, the materials from which the casting body (5) will be made will be mentioned below:
Zbog preciznog nasjedanja, tijelo nosača (3) je od slitine, u ovom slučaju odgovarajuće slitine koju dentalni tehničar i stomatolog žele upotrijebiti (neplemenite), dok će tijelo za lijevanje (5) biti izrađeno od akrilnog kompozita (pleksiglas). Akrilni materijal je zbog svojih svojstava izgaranja bez ostatka na visokim temperaturama pogodan za dodatne promjene. Prolaz za bočni vijak zajedno sa navojem koji su isključivo za ovu tehniku u obliku prstena (5c) izrađeni su također od slitine. Kako klip (5a) tijesno pristaje u urezano sjedište (5b), vrlo lako se može namjestiti u željeni položaj. Due to the precise fit, the carrier body (3) is made of alloy, in this case the appropriate alloy that the dental technician and dentist want to use (base), while the casting body (5) will be made of acrylic composite (plexiglass). Acrylic material is suitable for additional changes due to its combustion properties without residue at high temperatures. The passage for the side screw together with the ring-shaped thread (5c) exclusively for this technique are also made of alloy. As the piston (5a) fits tightly into the slotted seat (5b), it can be easily adjusted to the desired position.
Kako bi izum mogao ostvariti svoju tehničku karakteristiku, tj. da ove opisane sastavne dijelove zadrži u željenom obliku, potrebno je ulaganje u specijalne uložne, tj. vatrostalne mase koje se koriste u dentalnoj tehnici a koriste se isto tako za izradu protetskih konstrukcija. Postupak lijevanja slitina je poznat svakom laboratoriju. Akrilni materijal kao sastavni materijal tijela za lijevanje i klipa izgara bez ostatka u posebnim pećima koje postižu temperature i do 1000°C. Vatrostalna masa služi kao kalup za kasnije ulijevanje rastopljene slitine u tekućem stanju. Izgaranjem tijela za lijevanje (5) i klipa (5a) te ulijevanjem rastopljene slitine dobivamo nakon hlađenja slitine novo tijelo koje u cijelosti tvori tijelo nosača (3) spremno za daljnju upotrebu, ali u povoljnijem položaju prolaza za bočni horizontalni vijak (2h) tj. u potpunosti individualizirano a bitno je napomenuti da sadrži sve elemente prednosti ovog izuma. In order for the invention to realize its technical characteristics, i.e. to keep these described components in the desired shape, it is necessary to invest in special investment, i.e. refractory materials that are used in dental technology and are also used for the production of prosthetic structures. The alloy casting process is known to every laboratory. Acrylic material as a constituent material of the casting body and piston burns without residue in special furnaces that reach temperatures of up to 1000°C. The refractory mass serves as a mold for the later pouring of the molten alloy in a liquid state. By burning the casting body (5) and the piston (5a) and by pouring the molten alloy, after cooling the alloy, we get a new body that completely forms the support body (3) ready for further use, but in a more favorable position of the passage for the lateral horizontal screw (2h), i.e. completely individualized and it is important to note that it contains all the elements of the advantages of this invention.
Izum za povezivanje protetske konstrukcije koristi bočni horizontalni vijak (4). Vijak (4) se u cjelini sastoji od glave vijka (4a), tijela vijka (4b) te navoja na tijelu vijka (4c). Glava vijka (4a) je blago koničnog oblika sa smjerom sužavanja prema tijelu vijka (4b) kako bi u suštini, vijak (4) mogao sigurno povezati protetsku konstrukciju sa tijelom nosača (2) ili (3). Na širem dijelu glave vijka (4a) nalazi se ulaz tj. prihvat alata (4d) pomoću kojeg se može dotezati. The invention uses a lateral horizontal screw (4) to connect the prosthetic structure. The screw (4) as a whole consists of the screw head (4a), the screw body (4b) and the thread on the screw body (4c). The head of the screw (4a) is slightly conical in shape with a narrowing direction towards the body of the screw (4b) so that essentially, the screw (4) could securely connect the prosthetic construction to the body of the support (2) or (3). On the wider part of the screw head (4a) there is an entrance, i.e. a tool holder (4d) that can be used to tighten.
Navoj vijka (4c) na tijelu vijka (4b) je odgovarajući navoju u prolazu za bočni horizontalni vijak (2i) ili navoju prstena (5i). Ostatak tijela vijka (4b) je gladak i završava u zaobljenom vrhu tijela vijka (4e) koji obzirom da u cijelosti prolazi kroz tijelo nosača (2) ili (3) ima ulogu učvršćivanja sa suprotne strane od glave vijka (4a) i tako tvori dodatnu uporišnu točku na protetskoj konstrukciji. The thread of the screw (4c) on the body of the screw (4b) corresponds to the thread in the passage for the lateral horizontal screw (2i) or the thread of the ring (5i). The rest of the screw body (4b) is smooth and ends in the rounded tip of the screw body (4e), which, since it passes entirely through the body of the support (2) or (3), has the role of fastening on the opposite side of the screw head (4a) and thus forms an additional anchor point on the prosthetic construction.
Kao dodatnu ulogu, ovaj bočni horizontalni vijak (4) ima ulogu povezivanja ključa pomoću kojeg se sa radnog modela dentalnog tehničara situacija prenosi u usta pacijenta. Isto tako vijak (4) dozvoljava pomicanje protetske konstrukcije neovisno tijelu nosača (2) ili (3). As an additional role, this lateral horizontal screw (4) has the role of connecting the key by means of which the situation is transferred from the dental technician's working model to the patient's mouth. Likewise, the screw (4) allows movement of the prosthetic structure independently of the support body (2) or (3).
Tijelo nosača (2) ili (3) se zajedno sa uloškom (1) povezuje sa implantatom (0) pomoću glavnog okomitog vijka (6) na način da prolazi cilindričnim prolazima (1d), (2d) ili (3d). Taj vijak (6) je u suštini zajedno sa uloškom (1) poveznica originalnog sustava implantata sa ovim izumom. Obzirom na činjenicu da tijelo vijka (6b) zajedno sa navojem vijka (6c) neće biti izmijenjeno, taj vijak (6) ima prilagodbe ovom izumu jedino u svojoj glavi (6a) čija je tehnička karakteristika odgovarajuće nasjedanje na prsten (2a) ili (3a). Glava vijka (6a) također ima prihvat alata (6d) koji bi trebao biti odgovarajući prihvat alatu (4d) zbog olakšane upotrebe standardnog alata u ovom izumu. Dotezanjem glavnog vijka, izum kao sklop postaje potpuno nepomičan tj. učvršćen u željenoj poziciji. The body of the support (2) or (3) together with the insert (1) is connected to the implant (0) by means of the main vertical screw (6) in such a way that it passes through the cylindrical passages (1d), (2d) or (3d). That screw (6) is essentially, together with the insert (1), the link of the original implant system with this invention. Due to the fact that the body of the screw (6b) together with the thread of the screw (6c) will not be changed, this screw (6) has adaptations to this invention only in its head (6a), the technical characteristic of which is the appropriate fit on the ring (2a) or (3a ). The screw head (6a) also has a tool holder (6d) which should be a matching tool holder (4d) due to the ease of use of the standard tool in the present invention. By tightening the main screw, the invention as an assembly becomes completely immovable, i.e. fixed in the desired position.
