The resistance of self-threading retentive pins to failure in tension is due primarily to residual compressive forces in dentin generated during pin insertion. Examination of load-elongation curves and photomicrographs of samples also indicated that the interlocking of pin threads with dentin provides only a minor contribution to the peak retentive load.
