摘要 目的观察后牙CAD-CAM瓷嵌体的临床疗效。方法将我院门诊前磨牙及磨牙1类洞患者125例,随机分为两组:CAD-CAM瓷嵌体组(60例),复合树脂嵌体组(65例)。随访两年后,从边缘着色、边缘密合度、解剖形态、基牙继发龋、修复体折裂、颜色匹配等方面进行比较,并进行统计学分析。结果 CAD-CAM瓷嵌体组共随访59例,复合树脂嵌体组共随访63例。其中,CAD-CAM瓷嵌体组边缘着色A级57例,边缘密合度A级54例,外形A级55例,基牙继发龋B级1例,修复体折裂B级2例,颜色匹配A级56例。复合树脂嵌体组边缘着色A级53例,边缘密合度A级50例,基牙继发龋B级6例,修复体折裂B级2例,颜色匹配A级55例。CAD-CAM瓷嵌体组在边缘着色、边缘密合度、外形、基牙继发龋、颜色匹配等方面明显优于复合树脂嵌体组(P<0.05)。结论 CAD-CAM瓷嵌体是一种嵌入牙体内部以恢复缺损牙体形态和功能的瓷修复体具有较多优点,远期疗效好。
