Abstract
A submergible screw-type implant includes a longitudinal channel which directs bone chips towards the base of a bore in the patient's bone in which the implant is installed. These bone chips promote autogenous rapid regrowth of new bone to securely anchor the implant in place. In order to be able to position the implant at the most advantageous angle at the edentulous sight, angled abutments for supporting an artificial tooth structure or angularly adjustable abutments are provided. The angularly adjustable abutments may be in the form of a ball and socket joint in which the socket includes an inner casing having a peripheral extension that acts to lock the joint at the desired angle. Also, the support for an artificial tooth may include a shock-absorbing cushion to prevent some of the forces of mastication from disturbing the implant.
