Definitions

  • the invention relates to a dental implant having a first conical and a second cylindrical screw part, wherein the first screw part has a progressive thread and the second screw part has a fine thread and a circumferential groove is present at the threaded end of the fine thread. Furthermore, the invention relates to a kit comprising a dental implant.
  • Dental implants describe artificial tooth roots that are used in cases where the tooth and / or root are damaged or diseased.
  • the implants have a helical or cylindrical design and are implanted in the jawbone to replace lost teeth.
  • the implant performs the same function as its own tooth roots, as it grows directly into the bone. With the implant, later in the course of a treatment, crowns or bridges can be placed, which represent a dental prosthesis.
  • implant systems in which the connecting element to the tooth replacement (stump for crowns, ball head anchor for the fixation of prostheses) are worked in one piece with the implant body.

  • the implants made of titanium behave biologically neutral and also cause no allergic or foreign body reactions in the throat or mouth.
  • the prostheses to implants or implants may continue to be made of ceramic, in which case zirconia as a material is preferred.
  • This ceramic implant or a ceramic prosthesis consists of high-strength zirconia, which is extremely resistant to breakage and biologically highly compatible according to previous experience. It also has the advantage of getting significantly closer to the natural tooth color (white instead of gray), which can be particularly beneficial for esthetic restorations.
  • DE 10 2009 027 044 A1 discloses a multi-part dental implant with two shaft parts, one of which is designed as a structural part shaft and the other as a root partial shaft.
  • the shaft parts are connected to each other via an implant-abutment connection, wherein it is formed so that the one shaft part has an axial projection which engages in a corresponding axial recess of the other shaft part.
  • WO 2007 031 562 describes a multi-part dental implant which, on the basis of the geometry of the connection between root partial shaft and abutment shaft, ensures that the connection between the two elements is secure against rotation. It is ensured that the superimposed surfaces of root sub-shaft and body part shaft ensure a defined distance between opposing sealing surfaces, which causes a defined compression of a sealing element arranged between the sealing surfaces.
  • the abutment (also called the abutment) of a dental implant is applied to the implant by means of a retaining screw.
  • the abutments can compensate for inclinations of the implants implanted in the jawbone. In this case, however, it must be ensured that the abutment is designed to be relatively torsional relative to the implant in order to prevent the abutment and implant from twisting when the abutment screw (retaining screw) is screwed in or out. Also, the abutment screw (retaining screw) should be stuck, otherwise it too a relaxation of the structure can come.
  • abutments are screwed into the implant via abutment screws and tightened with a defined torque by means of a torque wrench.
  • the screwing tools and abutment screw used are standard hexagon or slot screwdrivers.

  • This micro-thread contains a number of small helical grooves.
  • WO 2004/098442 discloses a screw-in dental implant in which groove-shaped depressions are embossed on a relatively coarse thread, which run in the direction of the threads and there produce a micro-thread in order to increase the contact area between the dental implant and bone tissue.
  • the grub screw itself is essentially cylindrical and the thread is not progressively formed.
  • a disadvantage of the dental implants disclosed in the prior art is that they do not represent a safe barrier for bacteria and that numerous infections of the bore or the jawbone or the oral cavity can occur.
  • the growth time of the implants may be very long (one- or two-time approach), so that a patient has to reckon with massive quality of life limitations for a long period of time.
  • the invention thus relates to a dental implant, with a first preferably minimally conical and a second cylindrical screw member, wherein the first screw has a progressive thread progressively wider from the rounded apical end and the second screw has a subsequent to the progressive thread fine thread and a circumferential groove is present at the threaded end of the fine thread, the implant having at the cervical end an internal hexagon which is arranged in a conical depression.
  • the first screw member is preferably minimally tapered so that the conical portion is kept to a minimum to thereby mimic a tooth root shape, which in turn greatly simplifies the insertion of the implant.
  • the implant can preferably be designed in different lengths, in particular 3 mm to 20 mm, preferably 5 mm to 18 mm, particularly preferably 5 mm to 15 mm. Also, the diameter of the implant can be designed differently, with diameters of 1 mm to 10 mm, preferably 2 mm to 8 mm, particularly preferably 3 mm to 6 mm are advantageous. It was also completely surprising that an implant can be provided that can easily be screwed into the jawbone.
  • the implant serves, for example, to receive dentures, by means of which the purchase function can be restored.
  • the implant is threaded, which is progressive at the apical end.
  • the progressive thread is preferably a multi-threaded (eg, a double-threaded self-tapping thread) widening from the apical end to the cervical end, with the progressive thread joining a micro-thread or fine thread.
  • the fine thread can also be configured as a multiple thread (eg a three-start thread).
  • a progressive thread which is already known from US 6402515, becomes progressively wider from the rounded apical end of the implant and significantly improves the growth of the dental implant in the bone. With a particular As the thread depth increases apically, the load transfer is shifted to the more compliant cancellous bone. In addition, it has been found that the soil profile of the threads also leads lateral force perfectly into the bone and so contributes to an optimal relief of the cortex.
  • the first progressive screw part which is conical in shape, preferably has a taper of 0.001 0 to 10 °.
  • the length of the conically shaped first screw part is preferably 1 mm to 10 mm, preferably 2.5 mm to 7.5 mm, particularly preferably 4 mm to 5 mm.
  • the implant also has a fine thread that connects seamlessly to the progressive thread.
  • the second screw in which the fine thread is present, is cylindrical.
  • a fine thread in the sense of the invention particularly describes a thread which has a smaller thread profile than the thread of the first screw part. In particular, it has a smaller thread pitch.
  • the pitch of threads especially in the case of metric threads, designates the pitch, ie the distance between two thread stages along the thread axis, in other words, the axial path traveled by one revolution of the thread. It has surprisingly been found that a cylindrical design of the second screw part as a fine thread improves the growth of the bone and furthermore prevents it from being absorbed, whereby the growth of the connective tissue is promoted at the cervical end of the implant.
  • the cortical bone reacts strongly to load peaks of the implant body with remodeling processes, which often result in bone break-ups.
  • the progressive multiple thread of the implant is unique in a fine thread, in particular a three-pronged multiple thread (also referred to as three-thread) in the neck region of the implant over. It was completely surprising that this design generates a larger surface in the area of Kompakta and the forces of the implant are evenly introduced into the bone. This way, rebuilding processes are avoided - the bone remains stable.
  • the compacta designates the outer marginal layer of the bone (substantia compacta), which merges into the trabeculae and is covered externally by the periosteum.
  • the progressive multiple thread improves the primary stability, which is particularly important for a Fort- or early loading of the dental implant.
  • the primary stability of an implant is a crucial criterion for rapid and often successful subsequent osseointegration.
  • the progressive thread provides excellent uniform anchoring in the bone tissue.
  • the thread increases in strength upwards. It was completely surprising that the healing process is accelerated by the harmonious, even force distribution and thus immediate loading of the implants is made possible.
  • the progressive thread micro-movements of the inserted implant are largely prevented, which also promotes its healing and the integration of the bone.
  • the first screw part has a conical shape which, compared to a cylindrical shape when screwed into a straight cavity, substantially increases the primary stability and thus leads to a perfect adaptation in the cervical region.
  • High primary stabilities in the implants disclosed in the prior art are mostly achieved by conical implant bodies, but these inappropriately distribute the force into the various bone structures.
  • the forms suitable for the respective bone structure are connected to one another.
  • the implant (the first screw part of the implant) is conical; in the neck area (in the second screw part), the implant is cylindrical.
  • the dental implant preferably has a rounding at the apical end, which prevents anatomical structures (such as sinus floor, nasal floor, mandibular nerve or mucous membrane) from being injured when the implant is screwed in.
  • the dental implant has an internal hexagon at the cervical end, which is arranged in a conical recess. By means of the hexagon socket, a structure with the implant can be connected by a corresponding retaining screw. Such a structure and means for fixing it are described, for example, in WO 2007/022655 and WO 2007/022654.
  • the structure preferably has a connecting part formed as a hexagon, which is likewise of conical design and preferably fits snugly into the recess of the implant.
  • the retaining screw which serves to secure the structure, extends through the structure and can thus be screwed into the dental implant.
  • a shoulder of the retaining screw is supported on a shoulder of the structure, so that when the retaining screw is screwed in, the structure and the dental implant are contracted and secured.

  • the snap-on technique makes it easy to attach temporary crowns or impression devices.
  • cold welding in particular designates a process in which predominantly metallic workpieces of the same material can be connected to one another already at room temperature so that the connection comes very close to "normal" welding Due to the high quality of the material of the implant and the structure and the preferably smooth surfaces, many of the metal atoms on the two touch each other outside of the structure in the extreme limit of friction and a mechanical resistance (friction) arises Interfaces and the forces of attraction of these interconnect them into a stable atomic grid.

  • Fine thread turning into a conical thread At the thread end of the fine thread, there is a circumferential groove that can surprisingly prevent the penetration of bacteria and the development of infections.
  • the circumferential groove can also be referred to as threaded end reinforcement in the context of the invention. It was completely surprising that the risk of breakage and the weakening of the implant can be prevented by increasing the thread gain.
  • the threaded end reinforcement provides a preferred distance to the cervical implant end, at the transition to the inner cone to completion and contributes to the mechanical strengthening of the implant-construction load, so that a damage to the implant by acting chewing forces, especially in extra-axial loads can be prevented.
  • the implant consists of titanium.
  • titanium describes a metallic element from the fourth group of the periodic table.
  • titanium undergoes a direct molecular bonding with the bone, which is not the case with other materials.
  • bioinert property of titanium and the rapid integration of the implant into the bone can be improved by a roughening of the titanium surface.
  • the surface may preferably be etched and / or sandblasted.
  • the surface of the implant is preferably completely blasted with zirconium oxide and acid etched. In experiments with simulated body fluid, the deposition of bioapatite (calcium phosphate) at the implant surface could be detected. This demonstrates the high biocompatibility of the preferred material for subsequent solid anchoring in the bone.
  • the surface treatment of titanium significantly increases the surface area and achieves optimal osseointegration by increasing the attachment of bone-forming cells to the implant. In this way, integration of the implant or a homogeneous and stable bond with the surrounding bone can be achieved in the shortest possible time.
  • As a particularly preferred roughness of the surface of 0.5 to 5.0 Ra, preferably 1, 0 to 4.0 Ra, more preferably 1, 6 to 3.2 has been found. It was completely surprising that the preferred roughness not only improves the integration or connection of the bone tissue with the implant, but it is also possible to apply growth factors or other means for improving the growth on the surface.
  • the surface may have a nanostructure on which biologically active molecules are applied. These can also have an antibacterial effect, which can prevent infections.
  • Microstructured and nano-structured implant surfaces are particularly preferred since this improves and accelerates the osseointegration of the implant body.
  • the preferred structuring of the surface can provide an ideal surface geometry for the attachment of the bone cells.
  • the osteoblasts are guided during the colonization of the surface (osseo-production). Obviously, this even makes it possible for the horizontal shoulder surface of the implant to be surrounded by bone matrix, so that the soft tissue is supported and the predictability of the implant is facilitated.

  • the biological width of the connective tissue coating at the cervical implant end is in the prior art about 1.5 mm to 3.5 mm.
  • the preferred biological width takes into account the biological width of the soft tissues, which brings considerable advantages from an aesthetic and functional point of view.
  • the biological width particularly denotes the distance between the bone border and the edge of the implant or the border of the abutment.
  • the Zahmimp- lantat should wax without construction, so that it is advantageous to close its opening.
  • a locking screw can be used, which has a countersunk head with a hexagon and a thread, which is inserted into the thread of the tame implant.

  • the cutting grooves are preferably used as relief grooves for the bone chips.
  • the recess at the cervical end has a taper of 20 to 40 degrees, preferably 25 to 35 degrees, and more preferably 29 to 31 degrees. It has surprisingly been found that by a conicity of 20 to 40 degrees, a particularly stable press-fit fit between the dental implant and a structure can be achieved. Due to an optimal fit The elements can be particularly well prevented wobbling and damage to the implant or the structure.
  • the preferred conicity also makes it possible to dispense with complex and special connection elements between the abutment and the implant, which not only reduces the costs of the implant but also its size, which in turn considerably accelerates the growth of the surrounding bone tissue. Due to the taper and the absence of complex fasteners, the implant is universally applicable and can be used for a variety of structures. Furthermore, tests have shown that by a conicity of 25 to 35 degrees, the compound is optimally sealed against the ingress of microorganisms and so infections can be prevented. Furthermore, a conicity of 29 to 31 degrees is particularly advantageous, since the implant can be mass-produced and little material waste is produced.
  • the implant Due to the preferred conicity, the implant has a material thickness which accelerates the growth of the implant in the bone, since the dimensions of the teeth are reproduced. In addition, it is insensitive to occurring pressures, so that a long operability is ensured. It is further preferred that the recess at the cervical end of the implant has a taper of 30 degrees +/- 0.4 degrees (0.01 degrees to 10 degrees, preferably 0.2 degrees to 8 degrees, more preferably 0.5 degrees to 7 degrees).
  • this cone angle is advantageous because it does not have the usual disadvantages for prosthetic dentists compared to steeper cone angle. Because steep conical angles have a conical self-locking even at the early stage of implant trial implantation in the patient's mouth - as well as impression posts. This causes unwanted jamming of the body parts in the implant. What is unpleasant for the patients and for the dentist with very great effort and costly time is associated. By the preferred embodiment of the implant, these disadvantages can be avoided.
  • the preferred cone angles prevent this and are chosen in particular so that the conical self-locking occurs only after repositioning the implant abutment in the patient's mouth and finally only after tightening the prosthetic screw with deterministic torque in Ncm.
