Root-form, endosseous Dental implants for insertion into an opening in the jawbone of a patient include a body portion, a neck and/or neck/abutment portion above the body portion, and an internally-threaded shaft; a separate optional implant extender for placement atop the implant with a top surface that mimics the top surface of the implant, and includes a longitudinal passage that receives a healing screw, and a healing screw with a threaded distal end portion to pass through the longitudinal passage, engage the internal threads of the implant and hold the extender to the implant, or to cover the opening to the internally-threaded shaft of the implant where the optional extender is omitted.
A Dental implant system includes an implant body, for example, a screw anchor having external threads or a blade, which is implanted into a pre-formed cavity in a human jaw bone. The implant body has a vertically aligned bore having an axis, a conical top face, and at least three sockets radially spaced on the top face. A post having a conical bottom face, a single protruding pin, a bore and a wall at an angle of preferably 10-30 degrees from the axis of the pin, is fastened to the implant body by a screw. The post is eccentric to the implant body and its direction is determined by which of the socket holes the dentist inserts the pin of the post.
