This review assessed the available evidence on the performance of CAD/CAM monolithic implant-supported restorations bonded to titanium (Ti) inserts and bases, which has become a popular concept.
An electronic and manual search of PubMed databases was conducted to identify studies published in English between 2000 and 2016 on the performance of monolithic ceramic implant restorations with Ti inserts.
The initial search revealed 505 titles. Full-text screening was carried out for 70 studies, yielding 25 articles that met the inclusion criteria. No clinical studies could be identified regarding the performance of monolithic ceramic restorations bonded to Ti inserts. Laboratory studies on selected aspects and studies on similar prosthetic designs indicate that Ti inserts improve the overall fracture strength of ceramic abutments and crowns, protect the implant connection from wear, and offer a better marginal fit when compared with all-ceramic abutments.
While laboratory studies and evaluations of similar designs indicated promising outcomes, clinical studies that evaluate the performance of CAD/CAM monolithic implant-supported restorations bonded to Ti inserts and bases are needed.
本综述评估了关于粘结到钛（Ti）植入体和基底上的CAD/CAM整体式种植体支持修复体性能的现有证据，这已成为一个流行的概念。
对PubMed数据库进行电子和人工检索，以识别2000年至2016年间以英文发表的关于带有Ti植入体的整体式陶瓷种植修复体性能的研究。
初步检索显示有505个标题。对70项研究进行了全文筛选，产生了25篇符合纳入标准的文章。未找到关于粘结到Ti植入体上的整体式陶瓷修复体性能的临床研究。对选定方面的实验室研究以及对类似修复设计的研究表明，与全陶瓷基台相比，Ti植入体可提高陶瓷基台和牙冠的整体断裂强度，保护种植体连接免受磨损，并提供更好的边缘适合性。
虽然实验室研究和对类似设计的评估显示出有前景的结果，但仍需要临床研究来评估粘结到Ti植入体和基底上的CAD/CAM整体式种植体支持修复体的性能。
