An anchoring implant to be screwed into a hole and self-lock therein with secure stability. The implant, which may be used in dental, orthopedic or any of several non-medical applications, has a conically tapered profile with an aggressively-threaded, self-tapping apical end. A central region of the implant is formed with a plurality of burnishing edges each configured to apply a circumferentially sweeping compressive strain to the interior surface of the hole with a burnishing action while the implant is being screwed into position. A coronal end of the implant includes a corking feature to avert mushrooming around the perimeter of the hole. A central thread profile may extend through and intersect the burnishing edges to provide either enhanced self-tapping or enhanced corking functionality. The extreme coronal end comprises a platform for receiving an abutment or other fastening element via an internal connect feature.
