摘　　要：牙列缺损微创固定咬合重建是以微创修复理念为导向,以咬合重建为目标,涉及余留天然牙的微创修复、牙列缺隙区的种植修复以及咬合改变从可逆到不可逆的序列重建过程。牙体修复和种植修复共同完成咬合重建可借助数字化技术实现,口内扫描、锥形束CT、电子面弓、虚拟[牙合]架及计算机辅助设计与辅助制作等数字化技术可用于修复各阶段,如修复前的整体记录和评估、功能性修复空间的确定、过渡修复与正式修复过程中兼顾美学与功能的天然牙微创修复体和种植冠桥修复体的同期精准设计与制作,以及修复后随访记录和评估等循证医学资料的保存等。数字化技术的整合应用不仅可优化修复流程,还有利于提高修复的精准性。本文简要阐述牙列缺损微创固定咬合重建理念及修复过程中天然牙与种植体同期修复的数字化整合策略。The minimally invasive fixed occlusal reconstruction of dentition defect is a sequential reconstruction process involving the minimally invasive restoration of the remaining natural teeth,the implant restoration of edentulous areas and the occlusal change from reversible to non-reversible.The simultaneous completion of minimally invasive natural teeth restorations and implant-supported crowns or bridges in an ideal occlusal design shows the obvious advantages of digital integration.The use of digital technologies such as intraoral scanning,kinematic face bow,virtual articulator and computer aided design and computer aided manufacturing(CAD/CAM),could be integrated in each stage of occlusal reconstruction,including the overall documentations and assessments before the restoration,the determination of the functional restoration space,the precise design and fabrication of the provisional and final restorations taking into account both esthetics and function and the preservation of the follow-up documentations and assessments after the restoration.The integration process can optimize clinical process and improve restoration accuracy.This article briefly describes the concept of minimally invasive occlusal reconstruction of dentition defects and the integration strategy of digital sequential restoration.
