牙齿磨耗的测量方法

Methods of measuring wear of teeth

牙齿磨耗常见于牙病诊疗中,是上下牙齿相互作用的结果,可导致由牙本质暴露引起的局部不适和牙冠变短引起的美观问题,甚至危及口腔功能。若不加以控制,磨耗可能导致咀嚼肌功能失调且伴随生活质量的下降和健康系统的恶化。寻找测量磨耗的最佳方法是研究牙齿磨耗的关键,本文就牙齿磨耗的指数分级测量法和牙齿磨耗定量测量法中的牙尖高度测量、二维测量、三维测量法及其在口腔正畸、口腔修复和口腔颌面外科中的应用进行综述。

Tooth wear is frequently seen in dental practice. It is an important consequence of occlusal interactions. This can result in discomfort when areas of dentine become exposed, and lead to unacceptable aesthetic changes associated with reduced crown height and, in some cases, compromised function. If not controlled, wear could lead to poor mastieatory function with a concomitant reduction in quality of life and possible deterioration of systemic health. Therefore, when considering how to control wear, the best method of measuring wear must be found. This review focused on some universally used methods of measuring wear, such as the indexes for measuring the wear of tooth, the cusp height measurement method, two-dimensional digital measurement method and three-dimensional digital measurement method and application in orthodontics, prosthodontics and oral and maxillofacial surgeons.
