The two-in-one, self-threading, self-shearing pin: efficacy of insertion techniques.
An in vitro study has shown that the TMS minim two-in-one, self-shearing pin reaches maximum depth in a 2-mm pin channel before shearing off with insertion by a hand-turned wrench. The self-shearing, two-in-one pin did not achieve the full channel depth of 2 mm with insertion by an Auto Klutch handpiece.
