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.
自攻固位钉抗拉伸断裂的阻力主要源于钉植入过程中在牙本质内产生的残余压缩力。对样本的载荷-伸长曲线和显微照片的检查还表明,钉螺纹与牙本质的互锁对峰值固位载荷的贡献很小。
