Abstract： 目的 评估计算机辅助设计(computer aided design,CAD)与计算机辅助制作(computer aided manufacture,CAM)后牙全瓷修复体的3年临床使用效果,分析病例失败的原因.方法 使用CAD-CAM系统和可切削瓷块治疗32例后牙大面积牙体缺损患者,共修复14颗前磨牙和18颗磨牙.根据缺损的形态和体积分别制作11个嵌体、10个冠和11个髓腔固位冠,追踪观察3年.结果 28个修复体完好,2个修复体折断(磨牙嵌体和冠各1个)并重新制作,2个修复体边缘破损(磨牙和前磨牙嵌体各1个).结论 在正确选择适应证并严格按要求进行牙体预备的前提下,使用CAD-CAM全瓷修复能满足患者对咀嚼功能和美学的要求.
