摘　　要：前牙美学作为颜面部美学的重要组成部分,前牙颜色是影响前牙美学的主要因素之一,变色牙可通过漂白或修复治疗恢复牙齿正常颜色,但牙齿漂白技术治疗变色牙适应证较有限、远期效果维持欠佳,变色牙往往需要进行修复治疗。随着患者微创意识的提升,患者对于全冠修复接受率降低,贴面成为患者前牙美学修复的优先考虑方案。传统树脂贴面易着色,机械性能较差,现已少用于临床,瓷贴面性能稳定、半透性及机械性能佳,瓷贴面作为微创美学常规手段被用来修复变色牙,瓷贴面修复变色牙需要考虑基牙变色程度,其遮色能力不及全瓷冠。瓷贴面修复变色牙的遮色效果主要受瓷贴面材质、粘接剂及基牙三种因素的影响,此外义齿加工、邻牙颜色、口内环境等亦可造成瓷贴面修复体最终颜色的变化。通过阅读相关国内外文献,本文对影响瓷贴面遮色的三种主要因素综述,瓷贴面修复变色牙时可供临床医生参考。Anterior teeth esthetics is an important part of facial esthetics,and the color of anterior teeth is one of the main factors affecting the esthetics of anterior teeth.Discolored teeth can usually be restored to normal color by bleaching or restoration treatment.With the increase of patients'awareness of minimally invasive surgery,the acceptance rate of full crown restoration decreases,and veneer becomes the priority of patients'anterior esthetic restoration.Traditional resin veneers are easy to stain and have poor mechanical properties,which are rarely used in clinical practice.Porcelain veneers have good stability,translucency and mechanical properties.As a minimally invasive aesthetic routine method,porcelain veneers are used to restore discolored teeth.The restoration of discolored teeth with porcelain veneers requires consideration of the degree of discoloration of the abutment teeth,and its color blocking ability is not as good as that of all ceramic crowns.The opaque effect of porcelain veneers on discolored teeth is mainly affected by the material of porcelain veneers,cement and abutments.In addition,denture processing,color of adjacent teeth,and intraoral environment can also cause the final color change of porcelain veneers.This article reviews three main factors affecting the masking ability of porcelain veneers by referring relevant domestic and foreign literature,which can be used as a reference for clinicians when porcelain veneers are used to restore discolored teeth.
