摘要
贴面修复设计磨除牙体组织少、美学效果佳,在前牙美学修复中广泛应用。随着计算机辅助设计(computer aided design, CAD)与计算机辅助制作(computer aided manufacture, CAM)系统的发展,以及可切削瓷材料的不断研发,CAD-CAM工艺制作的瓷贴面在临床应用日益广泛。用于制作贴面的可切削材料主要包括瓷材料和复合材料,不同的材料类型具有各自的化学成分和性能。在CAD-CAM贴面修复体的临床应用中,其边缘适合性、抗折性影响修复的预后;并且,CAD-CAM贴面修复体的美学效果会受到材料的透光性、厚度、基牙及粘接材料颜色等多种因素的影响。本文对CAD-CAM贴面的材料类型、临床评价和预后效果、及数字化技术的应用作如下综述。
The veneer is widely used in aesthetic restoration of anterior teeth because of its greater preservation of tooth structure and better aesthetic outcome.With the development of computer aided design and computer aided manufacture(CAD-CAM),and the improvement of CAD-CAM materials,CAD-CAM veneers are increasingly used in the clinical practice.The CAD-CAM materials used to design the veneer restoration are mainly classified into ceramics and composite materials.The different types of CAD-CAM materials contain different chemical components and physical properties.The marginal adaption and failure load of CAD-CAM veneers affect the clinical outcomes and survival of milling veneers in the clinical applications.Moreover,the aesthetic outcome of CAD-CAM veneers are affected by the thickness and types of CAD-CAM materials,the color of abutment teeth and resin cements.This article reviewed the types of milling materials for CAD-CAM veneers,the clinical application and prognosis of CAD-CAM veneers,and application of digital technology in CAD-CAM veneer treatment.
