Description Implant kit intended for dental prosthesis

The innovation concerns an implant kit intended for a dental prosthesis, which has an implant to be inserted into the jawbone and an intermediate piece to be fastened therein and structural parts to be arranged on a connecting part of this intermediate piece.

Implantology has recently become increasingly important for the prosthetic treatment of patients. A titanium implant is inserted into the jawbone and, after it has grown into place, is fitted with abutments as a superstructure. Various companies currently offer very differently designed implants and abutments for such implants, with certain abutments belonging to certain implants. If the superstructure has to be replaced many years after an implant has been used, it is necessary to use the abutments intended for the implant again, as only these fit with the implant. However, it may be that at such a time abutments not intended for the respective implant are more advantageous than the original abutments, or that the original abutments are no longer available. In such a case, replacing the abutments would mean removing the implant and replacing it with a new implant adapted to the new abutments, which would be expensive and unpleasant for the patient.

The innovation is based on the task of designing an implant kit of the type mentioned above in such a way that

one and the same implant can be fitted with different components.

This task is solved in accordance with the innovation by providing intermediate pieces with different connecting parts for adaptation to different structural parts for the implant kit.

These spacers with different connecting parts allow you to adapt to the desired structural components by choosing a different spacer. This makes it possible to provide an implant inserted into the jawbone with different structural components than was originally the case. Furthermore, thanks to the innovation in the prosthetic treatment of patients, implants and structural components from different manufacturers can be combined with one another, whereby the spacer serves as an adapter and must be replaced each time.

The implant kit, in which a truncated cone-shaped crown abutment is placed on the intermediate piece as a structural component and is secured by means of a screw leading through the crown abutment into the intermediate piece, whereby the intermediate piece engages with a connecting piece in a recess in the crown abutment, enables the optional use of two currently very common types of structural components if, according to a further development of the innovation, the connecting piece and the corresponding recess have either a circular or hexagonal cross-section.

The innovation allows for various embodiments. For further clarification, reference is made to the drawing below. This shows

Fig.l a perspective view of the required

essential parts of an implant kit for a dental implant,

Fig.2 is a perspective view of two components of the implant kit that are modified compared to Figure 1.

Figure 1 shows an implant 1 to be inserted into a jawbone, which is designed as a hollow body and has an internal toothing 2. An intermediate piece 3, generally referred to as a compensation connector, can be inserted into this implant from above, which then has an external toothing 4 that engages in the internal toothing 2. Above the external toothing 4, a connecting piece 6 protrudes from a support flange 5 at an angle to the longitudinal axis of the intermediate piece 3, which in this embodiment has a circular cross-section.

A superstructure part 7 designed as a crown pillar can be pushed onto the connecting piece 6 from above, whereby the connecting piece 6 engages in a recess 8 of the superstructure part 7. A screw 9 is used to fasten the superstructure part 7 to the intermediate piece 3, which leads from above through the superstructure part 7 and is screwed into a threaded hole 10 in the connecting piece 6. Finally, a dental prosthesis 11 is pushed onto the superstructure part 7.

Implants are also available on the market which have a hexagon as a connecting piece on their top. If you want to use certain components for such implants for the implant 1 shown in Figure 1, then you have to use the intermediate piece 3a shown in Figure 2. This differs from the intermediate piece 3 in that instead of a cylindrical connecting piece 6, it has a connecting piece 6a with a hexagonal cross-section. This makes it possible to use a

Mounting part 7a with a hexagonal recess 8a is placed on the intermediate piece 3a.

Claims (2)

Protection claims 1. Implant kit intended for a dental prosthesis, which has an implant to be inserted into the jawbone and an intermediate piece to be fastened therein and superstructures to be arranged on a connecting part of this intermediate piece, characterized in that intermediate pieces (3, 3a) with different connecting parts (6, 6a) are provided for adaptation to different superstructures (7, 7a) for the implant kit. 2. Implant kit according to claim 1, in which a truncated cone-shaped crown abutment is placed on the intermediate piece as a structural part and is fastened by means of a screw leading through the crown abutment into the intermediate piece, the intermediate piece engaging with a connecting piece in a recess in the crown abutment, characterized in that the connecting piece (6, 6a) and correspondingly the recess (8, 8a) have either a circular or hexagonal cross-section.
