目的：本研究利用Cerec3D嵌体冠修复系统修复后牙大面积牙体缺损，并与传统桩冠修复进行临床比较，为今后的临床应用提供研究基础。方法选择行后牙冠修复的患者并随机分为2组。一组采用嵌体冠修复患牙（嵌体冠组），另一组采用桩冠修复患牙（桩冠组），2组进行对比追踪观察，所有入组患者在修复后不同时间点进行改良USPHS检查指标、分级标准和牙龈指数评价。采用SPSS 15.0统计学软件包进行数据统计学分析。结果嵌体冠组53例（63颗患牙），失访4例（5颗患牙）；桩冠组47例（63颗患牙），失访4例（4颗患牙）。2组修复后复查，各项指标各时间段组间及组内比较差异均无统计学意义（P＞0.05）。结论 Cerec3D嵌体冠适用于后牙大面积牙冠缺损的修复治疗，能够正常行使口颌功能。

ObjectiveTo compare the clinical effect of Cerec3D inlay crown with post crown in restoration of extensively damaged molar and provide basis for clinical use in future.MethodsPatients were divided into 2 groups randomly. In group 1, teeth were restored using Cerec 3D inlay crown (inlay crown group). In group 2, teeth were restored using Cerec3D post crown (post crown group). All patients were evaluated based on USPHS measure and gingival index. Statistical analysis with SPSS 15.0 package was carried out.ResultsThere were 53 patients with 63 teeth in inlay crown group, of which 4 patients (5 teeth) were lost. There were 47 patients with 63 teeth in post crown group, of which 4 patients (4 teeth) were lost. No significant differences were observed in the two groups.ConclusionCerec3D inlay crown is suitable for restoring extensively damaged molar, and could perform masticatory function.
