Dental implant, a template for inserting a dental implant, and a process for producing them
First Claim
Patent Images
1. A dental implant which comprises:
- a bone contact portion which has apically an extension portion thereof and which is adapted for insertion into an artificially produced opening in the jaw, which deepens a tooth socket at a bottom thereof;
a build-up portion which serves for fixing a crown or the like attachment;
the bone contact portion having a surface and a cross-sectional dimension and the extension portion having a surface and a cross-sectional dimension and the cross-sectional dimension of the extension portion being smaller than the cross-sectional dimension of the bone contact portion;
wherein the surface of at least one of the bone contact portion and the extension portion having a plurality of honeycombs which are arranged at uniform spacings and which extend in mutually adjoining relationship substantially over the entire surface thereof in the manner of a uniform pattern; and
wherein the extension portion is of a substantially cylindrical shape.

Abstract
The invention concerns a dental implant with a shaped, bone contact section for insertion into the tooth socket of a jaw and a built up section used for fastening a crown or similar material, where the bone contact section has an apical extension section which is made for the insertion into an artificially produced recess in the jaw which deepens the base of the tooth socket.

6. A process for the production of a dental implant which comprises the following steps:
-
forming an apical extension on an extracted tooth root with an extension portion; providing a contact-less measurement of the tooth root which i s extended by the extension portion; and forming a simulation of the tooth root which is extended by the extension portion using a biologically compatible, non-resorbable material on the basis of data produced by the measurement step. - View Dependent Claims (7, 8)

10. A process for producing a drilling template which comprises the following steps:
-
apically extending an extracted tooth root with an extension portion; forming a molding of the tooth root which is apically extended by the extension portion; inserting a sleeve of metal material into the molding so that a first end of the sleeve is in the region of an apical tip of the molded tooth root; filling a cavity formed between the sleeve and an inside wall surface of the molding with a hardenable material; hardening said hardenable material; and cutting the sleeve to length at a second end thereof opposite to the first end to produce an abutment for a drill or the like tool, for limiting a maximum drilling depth. - View Dependent Claims (11)
