Computer-aided design/computer-aided manufacture (CAD/CAM), as embodied in the CEREC system, enables the fabrication of high-quality esthetic ceramic restorations chairside. Resin cements are used to complete the clinical process, providing a high-strength, stress-free adhesive assembly. The current generation of CEREC technology can be used to create restorations with a repeatable 50-micron adhesive interface width. Systematic analysis of the literature on clinical trials of CEREC restorations indicates a high level of clinical success. CEREC technology is compatible with contemporary, conservative cavity preparation design and limits pulpal trauma by completing complex restorations in a single visit. The occlusal form of CEREC restorations can be machined with full regard to the patient's occlusion, using functionally generated pathway recordings.
以CEREC系统为代表的计算机辅助设计/计算机辅助制造（CAD/CAM）技术，能够在椅旁制作出高质量的美观陶瓷修复体。树脂粘结剂用于完成临床操作过程，可提供高强度、无应力的粘结修复体。新一代的CEREC技术可用于制作粘结界面宽度为50微米且具有可重复性的修复体。对CEREC修复体临床试验文献的系统分析表明其临床成功率很高。CEREC技术与当代保守的窝洞预备设计相兼容，并且通过一次就诊完成复杂修复体制作，从而减少了对牙髓的创伤。CEREC修复体的咬合形态可通过功能性运动轨迹记录，充分考虑患者的咬合情况进行加工制作。
