Abstract

Computer-aided design-computer-aided manufacturing (CAD-CAM) systems have been widely used as a fabrication method for restorations because of their high efficiency and accuracy, which significantly reduces fabrication time. However, molars with insufficient clearance or short clinical crown lengths require retention holes or grooves on the preparation, making it difficult to replicate the shapes with the CAM milling system. In these cases, restorations using the lost-wax method are selected. This article focuses on one-piece endodontic crowns (endocrowns) fabricated with a CAD-CAM system (CAD-CAM endocrowns), in which their posts and crowns are integrated. Articles from July 2012 to August 2023 were searched in PubMed with the keyword "endocrown". This review discusses the application of CAD-CAM endocrowns to molars from the viewpoint of model experiment (fracture resistance, adaptation) and clinical research. This technique, which allows margins and internal gaps to be set within the clinically acceptable range, is reported to be an effective way of restoring molars with high survival rates in clinical research.

使用 CAD-CAM 系统制作的一体式牙髓牙冠在磨牙上的应用

计算机辅助设计-计算机辅助制造（CAD-CAM）系统因其高效率和高精度而被广泛用作修复体的制造方法，大大缩短了制造时间。然而，对于间隙不足或临床牙冠长度较短的臼齿，需要在预备体上设置固位孔或凹槽，这使得 CAM 铣削系统难以复制其形状。在这种情况下，可选择使用失蜡法进行修复。本文主要介绍使用 CAD-CAM 系统（CAD-CAM 内冠）制作的一体式牙髓冠（内冠），其中的柱和冠是一体的。以 "内冠 "为关键词在 PubMed 上检索了 2012 年 7 月至 2023 年 8 月的文章。这篇综述从模型实验（抗折性、适应性）和临床研究的角度讨论了CAD-CAM内冠在磨牙上的应用。据报道，在临床研究中，这种可将边缘和内部间隙设置在临床可接受范围内的技术是一种修复磨牙的有效方法，其存活率很高。

期刊介绍： The Japanese Dental Science Review is published by the Japanese Association for Dental Science aiming to introduce the modern aspects of the dental basic and clinical sciences in Japan, and to share and discuss the update information with foreign researchers and dentists for further development of dentistry. In principle, papers are written and submitted on the invitation of one of the Editors, although the Editors would be glad to receive suggestions. Proposals for review articles should be sent by the authors to one of the Editors by e-mail. All submitted papers are subject to the peer- refereeing process.
