摘　　要：介绍牙体聚合度与洞型外展度测量两用卡尺的设计思想、基本结构、设计原理及使用方法。根据几何原理,设计制作出牙体聚合度与洞型外展度测量两用卡尺,既能测量全冠牙体预备后的牙体牙合面聚合度,又能测量嵌体牙体预备后的牙合向外展度。牙体聚合度与洞型外展度测量两用卡尺的设计科学合理,一尺两用,为口腔修复学教学和临床提供了一种方便、直接的测量工具。The design,basic structure and application method of a caliper for measuring convergence angle and abduction degree of dental cavity of teeth body are introduced. It can be used to measure the occlusal convergence angles of prepared teeth as well as the cavern-type abduction degree of prepared teeth. With scientific and reasonable design,this dual-usage caliper provides a convenient and direct measuring tool for prosthodontic teaching and clinical work.
