摘要： 目的:观察CAD/CAM玻璃瓷嵌体修复磨牙龋损的临床效果及分析修复失败原因。方法:选择85例患者的102颗磨牙为研究对象,其中Ⅰ类洞30颗,Ⅱ类洞72颗,CAD/CAM嵌体修复后6、12、18个月复诊,参考修正后的美国公共健康(USPHS)标准对其临床效果进行评价并分析修复失败原因。结果:治疗6个月时 CAD/CAM嵌体修复Ⅰ类洞成功率100%,Ⅱ类洞成功率95.8%,1例修复体脱落,1例食物嵌塞,1例术后敏感;治疗12个月时CAD/CAM嵌体修复Ⅰ类洞成功率96.7%,1例嵌体折裂,Ⅱ类洞成功率94.4%,3例嵌体脱落,1例牙髓炎;治疗18个月时CAD/CAM嵌体修复Ⅰ类洞成功率93.3%,2例嵌体折裂,Ⅱ类洞成功率93.1%,5例嵌体脱落。嵌体脱落全部发生在Ⅱ类洞深龋病例。粘接及洞型因素可能与脱落或折裂有关。结论:CAD/CAM玻璃瓷嵌体修复技术可作为磨牙龋损修复的可靠性选择,但应选择合适的适应症,严格遵循全瓷嵌体的制备、粘接原则。

Abstract: Objective: To observe the clinical efficacy and analyze the failure reason of CAD/CAM glass-ceramic inlay in restoration of molar caries. Methods: 85 patients with 102 molar teeth were recruited, including 30 molar teeth with typeⅠcavity and 72 with typeⅡcavity. According to the modified USPHS criteria, clinical efficacy were evaluated 6 months, 12 months, and 18 months after CAD/CAM inlay restoration, and the cause of repair failure was analyzed. Results: After 6 months of treatment, the success rates of type Ⅰ cavity was 100% and type Ⅱcavity was 95.8%; 1 case of inlay was fallen off, 1 case was food impaction, and 1 case was postoperative sensitivity. 12 months after treatment, the success rates of typeⅠcavity was 96.7%, 1 case was broken; the success rates of typeⅡcavity was 94.4%, 3 cases were fallen off, 1 case was secondary pulpitis. 18 months after treatment, the success rates of typeⅠcavity was 93.3%, 2 cases were broken, the success rates of typeⅡcavity was 93.1%, 5 cases were fallen off. All fallen inlay were occurred in typeⅡcavity with deep caries. Conclusion: CAD/CAM glass-ceramic inlay can be used as a reliable choice for the restoration of molar caries. But dentist should select suitable cases for a successful inlay restoration.
