摘　　要：根管治疗后及时合理的冠部修复是影响患牙保存的重要因素,随着粘接技术、修复材料的不断发展,椅旁计算机辅助设计/计算机辅助制作(CAD/CAM)髓腔固位冠已被越来越多地应用于根管治疗后牙齿的冠部修复。磨牙在口内主要承受压应力,具有相对较厚的颈周牙本质和宽大的髓腔,因此具备髓腔固位冠粘接修复的有利条件。本文针对磨牙根管治疗后椅旁CAD/CAM髓腔固位冠的特点、优势、生物力学变化、临床操作细节以及临床疗效等方面进行综述,为其临床应用提供参考。The timely and reasonable tooth restoration for endodontically treated teeth is significant for the success of root canal treatment.With the development of bonding technology and restoration materials,computer-aided design/computer-aided manufacturing endocrown is increasingly used in the restoration of endodontically treated molars.In particular,molars are characterized by relatively thick cervical dentin,large pulp cavity,and relatively low clinical crown,which provide favorable conditions for the adhesion and retention of the endocrown and can resist lateral forces.This article reviews the characteristics,advantages,mechanical properties,details of clinical operations of the endocrown,and clinical efficacy to provide a reference for clinical application.
