ABSTRACT:
A dental implant system includes an implant having its external geometry proportioned for securement within a human mandible. A junction between the implant and a complemental abutment of a dental prosthesis includes a journal that is defined by two bearing surfaces respectively preceding and following a threaded part of the junction. A longitudinal internal bore of the implant begins at a proximal open end of the implant and extends to a closed distal end, the bore includes the threaded part of the junction and is of substantially uniform diameter and pitch. A distal end of the bore defines one of the bearing surfaces and a proximal end of said bore defines the other bearing surface. The abutment of the dental prosthesis includes a male element which is complemental in all respects to the threaded portion of the bore and the bearing surfaces internal to the bore of the implant.
