ABSTRACT:
A screw-typed dental implant is featured having rounded threads for providing a controlled radial osteocompressive force against the threaded wall of bone tissue that was previously drilled and tapped. The thread profile provided by the tap is undercut below the external thread surface of the implant causing a compressive force to be exerted against the bone wall. The taps are designed to provide a given thread surface by varying the pitch angle. In this fashion, a greater undercut is provided for mandibular bone tissue as compared to maxillary bone tissue.
