摘要
近二十多年口腔瓷材料的物理机械性能和操作工艺得到了巨大的发展,全瓷修复技术因具有良好的美观效果和生物相容性,正在逐渐取代金瓷修复技术。数码全瓷修复技术是指采用计算机辅助设计和计算机辅助制造(CAD/CAM)技术制作完成全瓷修复体的技术,目前大量的全瓷修复体都是采用数码技术完成的,是近年来研究和临床应用的热点。本文将从数码全瓷技术的必要性、CAD/CAM技术、牙体预备与修复体的设计和制作、材料选择、全瓷粘接技术等方面讨论数码全瓷修复技术的现状和发展。
In recent twenty years,the physical and mechanical properties and the operation process of dental ceramic materials have gotten a huge development.All-ceramic restorations have good esthetics and biocompatibility,so they are replacing porcelain fused metal restoration gradually.Technology of digital all-ceramic restorations use computer aided design and computer aided manufacture(CAD/CAM) to manufacture all-ceramic restorations.At present,a lot of all-ceramic restorations are completed by digital technology which is a hot spot in recent researches and clinical applications.This article will summary and prospect of digital all-ceramic restorations by necessity of digital all-ceramic restorations,CAD/CAM,design and manufacture of restoration,material selection, all-ceramic bonding techniques.
