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.

Abstract: A dental implant system has an implant member, an abutment member and a transfer key with cooperatively engaging structures for aligning and orienting an abutment assembled on the implant member and for preparing a dental impression and mold which represents the implantation site and its relationship to adjacent teeth structures. The dental implant system includes an O-ring type abutment assembly with a reduced footprint, a surgical screw and bone screw insertion tool, a healing abutment that need not be removed during an impression taking procedure, and an implant coding system for selecting and identifying dental implants and implant analogs.

Abstract: A dental implant abutment arrangement for use with a dental implant has an abutment with a proximal retaining member and an axial bore. The retaining member is rotationally asymmetrical and has a transverse area that is large enough to resist rotation and axial motion of the abutment in a dental impression material. The axial bore has a tapered distal bore portion with an inner taper for matching an outer taper of an abutment receiving portion of an implant, a cylindrical proximal bore portion and an intermediate threaded portion having a small diameter than the distal and proximal bore portions and a larger diameter than an internal thread of the implant. The axial bore has distal and proximal steps between the distal bore portion and a distal end of the threaded portion and between the proximal bore portion and a proximal end of the threaded portion.

Abstract: A dental implant system comprising an implant member, an abutment member and a transfer key with cooperatively engaging structures for ensuring proper alignment and orientation of an abutment assembled on the implant member and for preparing an accurate dental impression and mold which represents the implantation site and its relationship to adjacent teeth structures. The abutment has the advantage of being easily removed for maintenance, repair or replacement with minimal or no discomfort to the patient.

The abutment has the advantage of being easily removed for maintenance, repair or replacement with minimal or no discomfort to the patient. The invention also includes a dental implant with an improved bone-engaging structure for enhancing implant stability and fixation as well as an O-ring type abutment assembly with a reduced footprint in its assembled state when compared with similar conventional systems. Further, dental reconstruction and abutment installation methods utilizing the dental implant system and instruments of the invention are disclosed.
