Tehnički problem Technical problem

Tehnički problem koji se rješava ovim izumom odnosi se na: The technical problem solved by this invention refers to:

- konstrukcijsko rješenje oseointegracijskog implantata koji će u sebi nositi protuupalni farmaceutski pripravak za sprečavanje upalnog procesa u čeljusnoj kosti. - the design solution of an osseointegration implant that will carry an anti-inflammatory pharmaceutical preparation to prevent the inflammatory process in the jaw bone.

Stanje tehnike State of the art

Implantacijom se, umjesto korijena zuba, u čeljusnu kost ugrađuju vijci koji služe kao umjetni korijen. Postupak se obavlja pod lokalnom anestezijom pri čemu se zarezuje zubno meso. Nakon toga se vijak umeće u kost, a meso zašije. Nakon određenog vremena (3-6 mjeseci) kontrolira se zahvat i učvršćuje nosač na koji naknadno dolazi umjetni zub. Pridržava li se pacijent preporučenih higijenskih mjera i ako redovito odlazi na kontrole, implantat može trajati 5, 10, pa i više godina. Općenito, rezultati takvih zahvata su odlični: novi zubi omogućuju potpunu slobodu pri jelu, ali i u društvenom životu. With implantation, instead of the root of the tooth, screws are inserted into the jawbone, which serve as an artificial root. The procedure is performed under local anesthesia, during which the gums are cut. After that, the screw is inserted into the bone, and the meat is sutured. After a certain time (3-6 months), the intervention is controlled and the support is fixed, on which the artificial tooth is subsequently placed. If the patient observes the recommended hygiene measures and goes for regular check-ups, the implant can last 5, 10, or even more years. In general, the results of such interventions are excellent: new teeth allow complete freedom when eating, but also in social life.

Postojeći implantati koji se koriste u stomatologiji za nadomjestak zuba ili za držanje zubne proteze izrađeni su od titana. Titan je materijal kojeg organizam u pravilu ne odbacuje. Implantati su izvedeni s navojem ili bez. Existing implants used in dentistry to replace teeth or to hold dentures are made of titanium. Titanium is a material that the body does not reject as a rule. Implants are made with or without thread.

Ipak, implantati se ne mogu umetnuti svima, jer vijcima od titana potreban je prostor: ako je kost preuska ili preniska, zahvat se ne može obaviti. Dodatni problem je u trajanju stomatološkog zahvata potrebnog da se zaokruži proces nadomjestka zuba ili ugradnje proteze, prvenstveno iz razloga učvršćenja implantata tj. osteogeneze, a poglavito ako se razvije upalni proces u kosti jer on će iziskivati dodatno povećanje trajanje procesa nadomjestka zuba. However, implants cannot be inserted for everyone, because titanium screws need space: if the bone is too narrow or too low, the procedure cannot be performed. An additional problem is the duration of the dental procedure required to round off the process of tooth replacement or prosthesis installation, primarily for reasons of implant fixation, i.e. osteogenesis, and especially if an inflammatory process develops in the bone because it will require an additional increase in the duration of the tooth replacement process.

Opis rješenja tehničkog problema Description of the solution to the technical problem

Primarni cilj izuma je spriječiti razvoj upalnog procesa u čeljusnoj kosti kod ugradnje implantata. The primary goal of the invention is to prevent the development of an inflammatory process in the jaw bone during implant installation.

Sekundarni cilj izuma je smanjiti trajanje stomatološkog zahvata potrebnog da se zaokruži proces nadomjestka zuba ili ugradnje proteze. The secondary goal of the invention is to reduce the duration of the dental procedure required to complete the process of tooth replacement or prosthesis installation.

Dodatni cilj izuma je poboljšati implantate koji su u upotrebi, a prvenstveno “Višedijelni stomatološki oseointegracijski implantat” opisanoga u prijavi patenta P990204A. An additional goal of the invention is to improve the implants that are in use, primarily the "Multipart dental osseointegration implant" described in patent application P990204A.

Endoimplantat, prema ovom izumu, obuhvaća implantat koji u svom tijelu ima izveden uvrt za smještanje protuupalnog farmaceutskog pripravka. Popratni crteži koji su uključeni u opis i koji čine dio opisa izuma, ilustriraju način izvedbe izuma i pomažu kod objašnjavanja osnovnih principa izuma. Endoimplant, according to this invention, includes an implant that has a screw in its body for placing an anti-inflammatory pharmaceutical preparation. The accompanying drawings, which are included in the description and form part of the description of the invention, illustrate the method of carrying out the invention and help explain the basic principles of the invention.

Crtež br. 1 - prikazuje endoimplantat u nacrtu – s dva djelomična presjeka Drawing no. 1 - shows the endoimplant in a plan - with two partial sections

Crtež br. 2 - prikazuje višedjelni stomatološki oseointegracijski implantat u tlocrtu – pogled s donje strane Drawing no. 2 - shows a multi-part dental osseointegration implant in plan view - bottom view

Endoimplantat (1) se postavlja u prethodno izveden uvrt u čeljusti. Uvrt može biti izveden manjeg ili većeg promjera od promjera endoimplantata (1). Veličina promjera uvrta ovisi o tipu implantata, tj. o tome je li implantat s navojem ili bez. The endoimplant (1) is placed in the previously made screw in the jaw. The screw can be made with a smaller or larger diameter than the diameter of the endoimplant (1). The size of the diameter of the screw depends on the type of implant, i.e. whether the implant is threaded or not.

Upućujući na crtež br. 1 i 2, može se vidjeti da je endoimplantat (1) izveden iz jednog dijela s dva uzdužna uvrta (2 i 3). Uvrt (2) s navojem služi za učvršćenje nosača umjetnog zuba, a uvrt (3) za “nošenje” protuupalnog farmaceutskog pripravka koji služi za sprečavanje razvijanja upalnog procesa u čeljusnoj kosti. Referring to drawing no. 1 and 2, it can be seen that the endoimplant (1) is made of one part with two longitudinal screws (2 and 3). Screw (2) with a thread is used to secure the support of the artificial tooth, and screw (3) is for "carrying" an anti-inflammatory pharmaceutical preparation that serves to prevent the development of the inflammatory process in the jaw bone.

Na svako nasilno ulaženje u tkivo organizam reagira blažom ili snažnijom upalom koja u slučaju i lakše infekcije može kompromitirati cijeli zahvat ili znatno produžiti sve vrijeme zahvata. U svrhu izbjegavanja takove komplikacije dragocjen nam je farmaceutski pripravak koji će onemogućiti proširenje primarne upale u blizini samoga implantata. The organism reacts to any forcible entry into the tissue with a milder or stronger inflammation, which in the case of even a mild infection can compromise the entire procedure or significantly extend the duration of the procedure. In order to avoid such a complication, a pharmaceutical preparation that will prevent the expansion of primary inflammation in the vicinity of the implant itself is valuable to us.

Claims

1. Endoimplant with a central screw and thread (2) in it, indicated by the fact that on the lower side of the implant (1) there is a screw (3) into which an anti-inflammatory pharmaceutical preparation is inserted.
