ABSTRACT:
A dental implant, placed into a socket formed in the jaw bone, is held in position by screws that pass through the jaw bone from the buccal cortical surface to the lingual cortical surface, and through the implant that is located between the cortical surfaces. Threads on the screw shank form and engage threads in the cortex on opposite sides of the jaw bone. The implant, when inserted in the socket and anchored by the screws, is immediately strongly held to the jaw's bony structure. Stresses applied to a prosthetic device, e.g., a tooth crown that is attached to the implant, are substantially borne by the cortex by way of the screws.
