1. A kit for creating and implanting a dental implant at an edentulous site in a jaw of a patient, comprising:
- an endosseous implant body having a top surface, a receptacle of said implant body extending downwardly from said top surface, an interior sidewall of said receptacle having screw threads, at least one noncircular receiving surface also formed in said interior sidewall;
a first, screw-threaded abutment having a head and a stem extending downwardly from said head, screw threads formed on said stem to mate with said screw threads of said receptacle in said endosseous implant body; and
a second, integral, press-fit castable and cementable abutment base having a head adaptable to have cast thereto an abutment body, a stem of said second base extending downwardly from said head, said stem cementable into and receivable in said receptacle of said implant body as an alternative to said receptacle receiving said stem of said screw threaded abutment, at least one noncircular locking surface formed on said stem to mate with said at least one noncircular receiving surface on said sidewall of said receptacle, such that when said press-fit abutment base is press-fit into said receptacle of said implant body, said press-fit abutment base will not be able to rotate in respect of said implant body.

Abstract
An endosseous dental implant system includes an endosseous implant body which is adaptable to receive either a screw-threaded abutment or a press-fit abutment base. An endosseous implant body replica and an impression pick-up are used in conjunction with the press-fit abutment base to get an exact translation of reference points of the implanted body from the patient'"'"'s mouth to a model, where a dental prosthesis can be fashioned without prior art alignment problems.
