Abstract

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.

摘要

本研究测量了四种不同设计的桩钉所能承受的最大拉力和扭力。1. 在拉力作用下，螺纹旋入式桩钉的固位力明显高于无螺纹桩钉。2. 在扭力作用下，螺纹旋入式桩钉和锯齿状桩钉的固位力均明显高于光滑面桩钉。
