The introduction and evolution of CAD/CAM technology into complete dentures fabrication brought high expectations in improving disadvantages associated with conventional methods.
The purpose of this review was to analyse the existing literature on computer-engineered complete dentures and to determine their advantages over the conventional dentures.
An electronic search of the English literature from January 1994 to March 2018 was performed in PubMed/MEDLINE, using the following keywords: CAD/CAM complete dentures, computer-engineered complete dentures, complete digital dentures, complete milled dentures, and rapid prototyping dentures.
A total of 179 English language titles were obtained from the database, and 14 were relevant to fulfil the purpose of this review. A review of 7 articles is summarized in 2 tables for presenting a comparison between CAD/CAM and conventional dentures in clinical and laboratory studies.
Following the review of articles that discussed the comparison between CAD/CAM and conventional complete dentures in clinical studies, it can be concluded that the main advantages of CAD/CAM dentures are the reduced clinical chair time and the number of visits, digital archiving, significantly higher retention, and more favorable clinical and patient-centered outcomes. As a result of the review of laboratory studies, superior mechanical and physical properties in CAD/CAM dentures were revealed, concerning enhanced accuracy of fit of milled denture bases, less denture tooth movement and increased toughness, ultimate flexural strength, and higher elastic modulus.
CAD/CAM技术引入全口义齿制作并不断发展，在改善传统方法相关缺点方面带来了很高期望。
本综述的目的是分析有关计算机辅助设计与制造的全口义齿的现有文献，并确定其相对于传统义齿的优势。
于2019年1月至2018年3月在PubMed/MEDLINE中对英文文献进行电子检索，使用以下关键词：CAD/CAM全口义齿、计算机辅助设计与制造的全口义齿、全数字化义齿、全铣削义齿和快速成型义齿。
从数据库中总共获得179个英文标题，其中14个与本综述目的相关。对7篇文章的综述总结在2个表格中，用于呈现CAD/CAM义齿与传统义齿在临床和实验室研究中的比较。
在回顾了讨论CAD/CAM与传统全口义齿在临床研究中比较的文章后，可以得出结论，CAD/CAM义齿的主要优点是减少临床椅旁时间和就诊次数、数字存档、固位力显著更高以及更有利的临床和以患者为中心的结果。通过对实验室研究的回顾，发现CAD/CAM义齿具有优越的机械和物理性能，包括铣削义齿基托贴合度提高、义齿牙齿移动减少以及韧性、极限抗弯强度和弹性模量增加。
