ABSTRACT:
An endosseous dental implant system includes a dental implant having a multi-sided projection at its top end and an internally threaded or unthreaded passage extending into the body of the implant through an opening in the projection at the top of the implant, and an abutment having an internal passage for receiving a fastener that passes through the internal passage of the abutment, and threads into the internal passage inside the implant. The abutment has a multi-sided internal cavity at its bottom end with each of the cavity sides perpendicular to the longitudinal axis of the abutment so that the cavity, when seated over the projection at the top of the implant, forms an anti-rotational, interlocking junction with the implant.
