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 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.
