ABSTRACT:
A dental implant for maintaining a dental prosthetic device in a fixed relation with respect to a jaw bone includes a support post in the form of an internally threaded hollow cylindrical sleeve. The support post is introduced into a complementay cavity formed in the region of the crest of the jaw bone. The support post is provided with at least partially threaded apertures which are spaced from each other along and angularly displaced from each other about the periphery of the support post. Self-tapping anchoring screws extend through preformed blind holes drilled in the jaw bone with the assistance of a jig forming part of the present invention. The preformed holes extend in a direction substantially normal to the support post and are aligned with the apertures in the latter. The anchoring screws threadedly engage the bone and the threaded portions of the support post without extending beyond the preformed blind holes. In this manner, the anchoring screws anchor and stabilize the support post in the jaw bone. The support post has a free end externally accessible in the region of the crest of the jaw bone for mounting a prosthetic device thereon. A jig and method of mounting the implant in the jaw bone is also described.
