前牙磨耗牙色修复材料的选择
Selection of tooth-colored restorative material for worn anterior teeth

摘要： 牙齿磨耗是一种不同于龋病、外伤或发育性异常所导致的牙齿硬组织表面缺损,其发生率较高。前牙磨耗主要影响美观及发音,前牙磨耗修复是常见的临床问题,若以美观为导向,常运用复合树脂及陶瓷等牙色材料进行修复。由于磨耗牙自身化学成分、微观形貌的改变及牙色修复材料性能的差异等诸多因素的影响,前牙磨耗牙色修复材料的具体选择是口腔修复学领域研究的热点之一,至今仍在不断研究探索,现就前牙磨耗复合树脂及陶瓷牙色修复材料的选择作一综述。
Abstract: Tooth wear is a common type of tooth surface loss distinguished from dental caries, trauma, or developmental abnormalities. Worn anterior teeth mainly influence the appearance and pronunciation of an individual. Restoration of worn anterior teeth is a common clinical problem. In consideration of aesthetic effects, worn anterior teeth are often restored using tooth-colored restorative materials, mainly composite resins and ceramics. During the restoration of worn anterior teeth, factors such as changes in chemical compositions, structures of worn anterior teeth, and various properties of tooth-colored restorative materials should be considered. Thus, the selection of tooth-colored restorative materials remains a controversial research hotspot in prosthodontics. This review systematically elaborates the selection of tooth-colored restorative materials, including composite resins and ceramics, for worn anterior teeth.
