Abstract
A dental implant system including a dental implant having an apical end, a top end, an anchoring portion adjacent the apical end. The dental implant is adapted to engage bone and has an axial length. The dental implant has an internally threaded opening of a predetermined depth accessible from the top end of the dental implant. The system includes an abutment receiving portion adjacent the top end for receiving an abutment. The system also includes an annular shoulder formed between the anchoring portion and the abutment receiving portion. The system also has an implant abutment having a peripheral wall and a central axial bore extending through the abutment.
Claims4
A method of attaching an abutment to a dental implant, comprising the steps of:
- providing an abutment having a peripheral wall and a substantially central axial bore extending through the abutment, the substantially central axial bore having a lower part, a central threaded bore part, and an upper part, the lower part of the substantially central axial bore having a conical interior wall adapted to form a locking taper connection with the abutment receiving portion of the implant;
- providing a dental implant, the dental implant comprising an apical end, a top end, and an anchoring portion adjacent the apical end, the anchoring portion being adapted to engage bone and having an axial length, the dental implant being provided with an internally threaded opening of a predetermined depth accessible from the top end of the dental implant, an abutment receiving portion adjacent the top end of the dental implant for receiving the abutment, the abutment receiving portion being provided with at least one longitudinal groove of a selected shape extending downwardly a predetermined length from the top end of the dental implant, the abutment receiving portion being tapered toward the top end;
- providing an annular shoulder formed between the anchoring portion and the abutment receiving portion;
- providing an insertion tool that engages the internal threaded bore of the implant;
- and
- applying an axial seating force to the abutment with the insertion tool;
- and
- urging the abutment and the implant together to form a locking taper connection;
- wherein the insertion tool is removed upon the formation of the locking taper connection prior to cementation of the crown.
