Abstract

A technique is described in which a standardized post system is used as a cross pin. The pin is partially embedded in the mesial or distal aspect of the abutment tooth and the remainder of the pin diameter is incorporated in the metallic substructure of the fixed partial denture. The cemented pin will add retention and resistance to the fixed partial denture. The differences between threaded and smooth cross pins are discussed.

摘要

本文描述了一种技术，其中使用标准化的桩系统作为交叉桩。该桩部分嵌入基牙的近中或远中面，桩直径的其余部分并入固定局部义齿的金属亚结构中。粘结的桩将增加固定局部义齿的固位力和抗力。文中讨论了螺纹交叉桩和平滑交叉桩之间的差异。
