A dental implant system includes an implant (16) having its external geometry proportioned for securement within a human mandible. A junction between the implant (16) and a complemental abutment (18) of a dental prosthesis includes a journal defined by two bearing surfaces respectively preceding and following a threaded part of the junction. A longitudinal internal bore (22) of the implant (16) begins at a proximal open-end of the implant (16) and extends to a closed distal end. The bore includes the threaded part (25) of the junction and is of substantially uniform diameter and pitch. A distal end (24) of the bore defines one of the bearing surfaces and a proximal end (26) of said bore defines the other bearing surface. The abutment (18) of the dental prosthesis includes a male element (20) which is complemental in all respects to the threaded portion of the bore and the bearing surfaces internal to the bore of the implant. |
