Retention of dowels subjected to tensile and torsional forces.
This investigation measured the maximal tensile and torsional forces sustained by four different designs of dowels. 1. Under tensile force, the threaded screw-in dowels were significantly more retentive than the unthreaded dowels. 2. Under torque, both the threaded screw-in and serrated dowels were significantly more retentive than the smooth-sided dowels.
