Problems solved by technology

In terms of production, such form-fitting elements are relatively difficult to produce, wherein in some cases the complete depth without an annular seat / centering ring for centering, mounting and fixing of the spacer sleeve relative to the basic body is not particularly advantageous

Embodiment Construction

[0057] Such as figure 1 As shown, the single-tooth implant in the illustrated embodiment includes a matrix 10 (which is shown as figure 1 shown closed at its top), bottom and top, and has a blind hole 12, such as figure 1 Open towards the coronal end as shown, the top has an internal thread 14 close to the top of the blind hole 12 . A set screw 70 (not shown in this figure) can be screwed into this internal thread. Adjacent to the internal thread 14 of the base body 10 in the coronal direction is a hollow-cylindrical annular recess 16 having a larger internal diameter than the internal thread 14 . In the form shown, the annular recess 16 has three segments (18; 20; 22).

[0058] The annular recess 16 has a guide section 18 coronally adjoining the internal thread 14 . The guide section 18 coronally adjacent to the annular recess 16 is a form-fitting section 20, which has a coronally increasing inner diameter relative to the guide section 18 and a coronal inner wall, acco...

Abstract

The invention relates to a single tooth implant for a fixed dental prosthesis, said implant comprising a substantially cylindrical main part which can be inserted into a bore in a jaw bone; an abutment which can be inserted into the annular seat in the main part, said abutment having a bore for receiving a retaining screw and a securing head for the dental prosthesis; and a retaining screw which can be inserted into the blind hole of the main part and traverses the abutment.

Description

technical field [0001] The invention relates to a vibration-resistant single-tooth implant for fixing dental prostheses having the features of claim 1 . Background technique [0002] In a single-tooth implant as known from DE 40 28 855 C2 and also the subject of DE 195 09 762.9-32, protection against rotation is provided in which there is an annular recess based on the base body and a spacer sleeve form matching element complementary to the annular recess , On the front end, a base body form matching element is provided for the centering ring of the spacer sleeve. In terms of production, such a form-fitting element is relatively difficult to produce, wherein in some cases the complete depth without an annular seat / centering ring for centering, mounting and fixing of the spacer sleeve relative to the base body is not particularly advantageous. [0003] A similar problem occurs with another dental implant, as proposed in DE 37 35 378, because the form-adapting elements of the...
