Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
151 words
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.
Claim 2
Dependent Claim
151 words
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.
Claim 3
Dependent Claim
31 words
An implant as set forth in claim 1, wherein the extension portion has an end thereof and is of a substantially cylindrical shape and is rounded off at the end thereof.
Claim 4
Dependent Claim
34 words
An implant as set forth in claim 1, wherein the extension portion has a longitudinal axis which is angled through a predetermined angle with respect to a longitudinal axis of the bone contact portion.
Claim 5
Dependent Claim
29 words
An implant as set forth in claim 1, wherein at least one of the surface of the bone contact portion and the surface of the extension portion is roughened.
Claim 6
Dependent Claim
42 words
An implant as set forth in claim 1, wherein the bone contact portion simulates the tooth root shape of a tooth to be replaced and is of such a dimension that it forms a press fit when inserted into the tooth pocket.
Claim 7
Dependent Claim
74 words
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.
Claim 8
Dependent Claim
74 words
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.
Claim 9
Dependent Claim
42 words
A process as set forth in claim 6, including the step of: correcting cross-sectional dimensions of a portion of at least one of the tooth root and the extension portion by a predetermined value prior to the operation of forming the simulation.
Claim 10
Dependent Claim
29 words
A process as set forth in claim 7, wherein the operation of forming the simulation is implemented under computer control by one of an erosion process and water-jet cutting.
Claim 11
Dependent Claim
75 words
A method of making the dental implant of with claim 1, 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 is 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.
Claim 12
Dependent Claim
123 words
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.
Claim 13
Dependent Claim
123 words
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.
Claim 14
Dependent Claim
67 words
A process as set forth in claim 10, wherein the step of cutting the sleeve to length includes the following steps: inserting a measuring gauge of predetermined length into the sleeve as far as the end of the molding of the extension portion; and marking off a dividing line on the sleeve in the region of the second end by a marking element of the measuring gauge.
Claim 15
Dependent Claim
132 words
A process for producing a drilling template for a dental implant in accordance with claim 1, 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.
