摘　　要：根管治疗(root canal treatment,RCT)后大面积硬组织缺损后牙修复仍然是一个临床难题。随着材料发展和数字化技术普及,髓腔固位冠(endocrown)结合高强度陶瓷材料,计算机辅助设计与制造(computer-aided design/manufacturing,CAD/CAM)以及可靠的粘接材料,由于其微创、美观、便捷等优点受到患者和修复医生的青睐。本文就后牙髓腔固位冠与桩核冠比较修复材料、对接设计、适合性研究、纤维加强型树脂应用、预后研究等进展作一综述。Restoration of endodontically treated posterior teeth with extensive coronal loss is still a clinical problem.With the development of dentistry material and widely employment of computer-aided design/manufacturing（CAD/CAM）,endocrowns combined with high-strength glass ceramics,CAD/CAM,and reliable adhesive systems are widely accepted by both patients and prosthodontists for their minimal invasion and esthetic characteristics.This paper reviews the research progress on the comparison between endocrowns and conventional restoration,marginal preparation design,adaptation of endocrowns,ceramic materials,application of FRCs,and prognostic evaluation.
