Definitions
- the present invention relates to a dental prosthesis system comprising an implant for osseointegration into a jawbone and an abutment to be inserted into the implant according to the preamble of patent claim 1.
- dental implant or dental implant for a variety of dentures systems have been offered on the market for some years and used very successfully.
- the terms dental implant or dental implant are usually for the dentures per se and must not be confused with the actual implant body, which is correctly referred to as tooth root replacement as an implant.
- the terms dental implant and implant body or implant are clearly separated, wherein the dental implant designates the dental prosthesis, which encloses the implant body for anchoring in the jawbone.
- the market is dominated by two-part and three-part dental implants, whereby the three-part dental implants for replacement of a single tooth usually comprise an endosteal implant or implant body, an abutment (also referred to as connection part or implant post) and a crown, bridge or other prosthetics build up.
- the abutment allows the dentist to align the crown with the implant, so that their exact position in the dental arch is not solely dependent on the position of the implant body. For this, the abutment must be positioned in the implant according to a predefined orientation after the implant is anchored in the jaw.
- Common implant forms include leaf, needle, screw, cylindrical and conical implants, each used for different indications. Basically, subperiosteal and endosseous implants can be used. Often Endosseous implants used are essentially cylindrically constructed and are screwed or punched into a bore in the jawbone or directly into the jawbone. At the coronal end, the implants are provided with an open blind bore for receiving the abutment. In the last few decades, titanium has been the main material used because it has an e-modulus similar to the jawbone and is excellently biocompatible. Alternatively, ceramics, for. As zirconia ceramic, are used. In such dental implants, the crown, usually made of conventional dental ceramics and / or metal, is glued or cemented to the abutment or the one-piece implant / abutment construction or attached thereto by mechanical means.
- WO 2006 / 084346A1 discloses an implant system with an abutment made of a non-metallic material, which comprises an implant and a prosthesis carrier which again comprises an abutment and a collar element.
- Essential features of the implant system are that the parts of the implant system are pushed into one another linearly and glued together.
- the abutment has, between a substantially cylindrical basal post and a head portion, a cylindrical neck portion having a lower protrusion which is designed as a polygon and which serves for radial positioning of the abutment in a corresponding receptacle in the shoulder of the implant.
- the central hole in the implant for receiving the basal post is provided with an internal thread, which allows the screwing of a screw cap or a spacer during the healing process.
- a collar element is slipped over the neck area of the abutment and the basal post is glued into the threaded hole of the implant.
- the abutment has a central, continuous axial channel for draining off the adhesive.
- a disadvantage of this system is the great technical effort to produce the central axial channel in the abutment and the mechanical stresses and strains to which the abutment is exposed.
- an implant system with an implant and an abutment in which the abutment is provided with means for rotationally locked mounting of the abutment in the implant.
- a receiving opening in the implant is designed such that the abutment with a basal portion can be inserted into the receiving opening in the desired angular position substantially in the desired angular position in the implant and is secured in this position by a separate screw on the implant.
- the invention is based on the object to provide a dental prosthesis system that reduces the above-mentioned disadvantages. Further, it is an object to provide a dental prosthesis system which has good mechanical stability, minimizes the risk of crevice or misalignment, can be positioned in a simple and accurate manner, reduces inconvenience to the patient, and is cost-effective.
- a dental prosthesis system comprises an implant for osseointegration into a jawbone and an abutment with an insertion stem insertable into a receiving opening of the implant.
- At the insert stem at least one at least partially radially to a longitudinal axis of the insert trunk, or the receiving opening, extending paragraph is formed, which can serve as a locking shoulder.
- On an inner peripheral surface of the receiving opening at least one at least partially radially extending stop is provided. It is in a first rotational position between insert stem and implant, the Ein 1500 loftposition, the abutment relative to Implant axially movable, preferably exclusively axially movable. Paragraphs and stops are offset in this position in the circumferential direction and can be performed in the axial direction past each other.
- the abutment is inserted into the receiving opening and inserted axially in the insertion rotational position into the receiving opening until it is in a starting position, in which a shoulder is arranged in an axial insertion direction behind a stop. From the home position, the abutment can be rotated to a second rotational position, the engaged rotational position or the locked rotational position.
- the insertion stem is rotated relative to the implant by an angle with respect to the first rotational position about the longitudinal axis so far that at least one shoulder engages behind a stop so axially that the abutment is fixed in the implant in the axial direction. This means that a movement in an opposite axial direction against the insertion between the implant and abutment is blocked.
- a stop in the receiving opening of the implant can thus serve as a blocking stop against which a shoulder of the insertion stem strikes in the engaged rotational position, thus blocking the removal or pushing out of the abutment from the implant.
- the at least one stop in the implant can therefore form a positive axial locking between the implant and the abutment in the second rotational position with the at least one shoulder of the abutment.
- shoulders and stops are positioned so that the abutment assumes a desired position relative to the implant after being threaded into the locking rotational position.
- an adhesive can, for. B. be used in a known manner, an adhesive.
- the abutment remains in the intended axial position in the implant, without the need for axial pressure on the abutment.

- the several paragraphs can be distributed on one level in the circumferential direction, ie perpendicular to the longitudinal axis, around the insert trunk. It is also possible to provide shoulders at different levels along the longitudinal axis, ie at different axial positions. Thus, the shoulders and stops within the receiving opening may allow locking at various axial positions along the abutment.
- the shoulders are provided at a proximal end of the insertion trunk and the abutment can thus be locked at the lowest point in the implant.
- the heels can also be arranged, for example, centrally on the insert trunk.
- An insertion stop can be provided in the receiving opening of the implant and an insertion counterstop can be provided on the insertion stem, which limit the axial insertion movement of the abutment when the abutment is inserted into the implant.
- the abutment between the insertion stop and the insertion stop can thus define the axial starting position for the rotational movement, from which the abutment is brought from the insertion rotational position into the engaged rotational position.
- the insertion stem is preferably inserted completely into the implant. Insertion stop and insertion counter stop are advantageously provided in such a way that they abut each other even after the abutment has been rotated into the engagement position. The abutment is thus secured in both axial directions and is held firmly in this position.
- the insert stem is located with a basal surface on a base in theracöffnu ng when the abutment is inserted into the starting position.
- the basal surface forms an insertion stop and the base surface forms an insertion counter stop.
- a rotation stop can be provided in the receiving opening and a rotation counter-stop can be provided on the insert trunk, which can be a rotation counter stop Limit the rotational movement of the abutment relative to the implant.
- the rotatory attacks can z. B. as ribs or edges on the peripheral surfaces of I implant and abutment can be provided which extend substantially in axial Richtu ng.
- the rotary stops are preferably positioned in such a way that the rotation movement is blocked already after a rotation path of 1 ° 20 °, preferably below 60 °, in particular at 45 °. In principle, however, it is also possible to provide a half turn or an almost full turn.
- the Verriegelu ngsposition thereby determines a predefined Ausrichtu ng of the abutment relative to m implant, so that a on the abutment to be brought tooth structure can also be provided in a predefined Ausrichtu ng.
- At least one shoulder of the insert stem and at least one stop in the receiving opening can be designed in such a way that the abutment and implant are connected to one another by a kind of bayonet connection.
- the heels are guided while turning along the inclined surfaces attacking and can be brought into a kind of clamping fit.
- the heels on the insert stem may be formed by depressions in a lateral surface or by projections protruding radially from the lateral surface, such as ribs, or by a combination of both.
- the insert stem may have a circumferential surface with a non-circular peripheral shape that fits into a correspondingly non-circular inner peripheral shape of the receiving opening of the implant, with a game in the direction of rotation between abutment and implant remains.
- the insert stem can also have a non-circular peripheral shape only in the peripheral region of the shoulders.
- the lateral surface and the inner circumferential shape may be polygonal in shape such that there are one or more rotational positions in which the abutment can be inserted into the implant.
- the regions of the peripheral surfaces with a smaller radius can serve as rotation stops between the abutment and the implant, so that the abutment and implant can only be rotated within the peripheral sectors with a larger radius around this clearance.
- the paragraphs can be done by depressions z. B. in the form of incisions or grooves in the lateral surface are provided so that the paragraphs do not protrude substantially radially over the lateral surface.
- the stops may be formed by projections in the inner peripheral shape of the receiving opening, which project substantially radially from the peripheral surface.

- the guide surfaces can z. B. radially inwardly projecting. Or the guide surfaces are formed by a non-circular inner peripheral surface of the receiving opening, as mentioned above.
- the guide surfaces for the Abutmentab preferably end at the attacks of Receiving opening, so that the insert trunk can be twisted, as soon as the stops were passed.
- the axial guide surfaces or grooves can pass into further guide surfaces or grooves, which are aligned in the circumferential direction and lead to the attacks of the receiving opening.
- the stops can form such a circumferential guide surface.
- the insertion stem can be axially guided positively along the guide surfaces in the implant until the axial starting position is reached, in which the abutment can be rotated.
- the abutment is positively guided along the guide surfaces and guided in the predefined orientation with respect to the implant.
- the insert stem and the receiving opening are cylindrical in a simple manner. In principle, they can also have a conical shape.
- a dental prosthesis system In contrast to a screw connection between implant and abutment or an axial press-fitting of the abutment, a dental prosthesis system according to the present invention enables a continuous linear insertion movement. With a short rotational movement, the abutment can be brought into a desired predefined position, which can be maintained without constant effort. Quick and easy handling without repeated rotational movements enables easy insertion and positioning of the abutment in the implant.

- the abutment 2 is inserted axially into the implant 1 so far that the basal surface 17 of the insertion stem 6 abuts against the base 16 of the implant 1.
- the skirt 12 is at the top 13.
- the base 16 and the edge 13 form an insertion stop and the basal surface 17 and the skirt 12 form a Ein drunkurgianschlag, which limit the insertion movement in the retracted position.
- the abutment 2 can therefore not be pushed further into the implant 2 in the axial insertion direction.
- the abutment of the insert trunk 6 is aligned relative to the receiving opening 4 in such a manner in a first rotational position that the recesses 10 opposite the stops 5 and the paragraphs 9 can slide past between the attacks.
