天然牙齿在咀嚼过程中产生磨耗,过度的磨耗造成咀嚼系统的功能紊乱和美学缺陷。通过体外实验的方法可以研究磨耗的病因和过程,评价某种口腔修复材料的磨耗性能。本文回顾总结了修复体、牙体组织体外磨耗实验的相关影响因素,为模拟牙体组织的磨耗过程、合理设计体外磨耗实验装置提供参考依据。 Natural teeth produce wear during mastication, excessive wear resulting in maladjusted system disorders and aesthetic defects. By in vitro experiments can study the etiology and process of wear, evaluate the wear properties of a certain oral prosthetic material. This article reviews and summarizes the related factors that affect the wear test of prosthesis and tooth tissue in vitro and provides a reference for simulating the wear process of tooth tissue and rationally designing the experimental device for in vitro wear.
