An anchor to be screwed into a hole with high primary stability and eventually even higher secondary stability. A right hand thread form winds with continuous turns along the body of the anchor. A trailing flank of the thread form is back-angled. The central region includes an array of flutes having left-hand helical twist. Each flute is composed of distinct flute segments. A condensing ramp is formed along the crest of the thread form between two circumferentially-adjacent flute segments. Each condensing ramp is pitched about 20° so as to apply a localized compressive strain to the interior surface of the host bone with a densifying action when the anchor is screwed into the prepared hole. The condensing ramps create induced stress and super-activated zones in the bone directly adjacent to healing chambers formed by the flute segments. The healing chambers draw bone to naturally encourage and promote healing.
