The purpose of the present review was to survey the available literature on computer-aided design/computer-aided manufacturing (CAD/CAM)-produced resin composite materials to provide clinicians with a current overview of the key components necessary for daily clinical use. An electronic search was conducted in the PubMed database. Peer-reviewed articles in English language on the use of resin composites in CAD/CAM dental crowns were included. A total of 122 full-text articles were identified, 15 of which were selected during the initial review. Two additional articles were also discovered through a manual search, to obtain a final total of 17 articles included in the present review. Of these, 16 were to studies, and one was an study. Findings from the studies indicate that resin composite block materials for CAD/CAM applications demonstrate excellent physical properties and are appropriate for the clinical restoration of premolars and molars. However, the study reported a low 3-year success rate, but high survival rate for resin composite CAD/CAM crowns placed in the premolar region. The key to ensuring the successful prognosis of a resin composite CAD/CAM crown is to ensure that all steps-such as proper case selection, abutment tooth preparation, occlusal adjustment, and bonding-are accurately performed.
本综述的目的是调查有关计算机辅助设计/计算机辅助制造（CAD/CAM）生产的树脂复合材料的现有文献，以便为临床医生提供日常临床使用所需关键成分的最新概述。在PubMed数据库中进行了电子检索。纳入了关于树脂复合材料在CAD/CAM牙冠中应用的英文同行评审文章。共识别出122篇全文文章，其中15篇在初步评审中被选中。通过手工检索又发现了另外两篇文章，最终本综述共纳入17篇文章。其中，16篇是观察性研究，1篇是病例系列研究。观察性研究的结果表明，用于CAD/CAM应用的树脂复合嵌体材料具有优异的物理性能，适用于前磨牙和磨牙的临床修复。然而，病例系列研究报告树脂复合CAD/CAM牙冠在前磨牙区域放置时3年成功率较低，但生存率较高。确保树脂复合CAD/CAM牙冠预后成功的关键是确保准确执行所有步骤，如正确的病例选择、基牙预备、咬合调整和粘结。
