目的:观察间接树脂高嵌体修复磨牙大范围缺损的临床效果。方法:选取磨牙大面积缺损患者104例(患牙110颗),随机分成两组,分别采用间接树脂高嵌体修复和光固化树脂高嵌体充填各55颗牙,瞩患者两年复诊,参照USPHS标准进行评估。结果:两年复查时两组修复体的牙体完整性差异无统计学意义(P>0.05);在修复体情况、边缘适合性、表面粗糙度、继发龋、磨耗方面,间接树脂高嵌体组优于高嵌体充填组(P<0.05)。结论:间接树脂高嵌体修复大范围缺损的磨牙能取得很好的临床效果,值得推广。
Objective: To observe the clinical effect of indirect resin inlay restoration of large molar defect. Methods: One hundred and four patients (110 teeth) with large molar defect were selected and randomly divided into two groups. Each group was implanted with 55 indirect implants and 55 light implants respectively. The patients were referred for two years according to USPHS Criteria for evaluation. Results: There was no significant difference in dental integrity between the two groups during the two years (P> 0.05). In terms of prosthesis, marginal fit, surface roughness, secondary caries and abrasion, The body group was better than the high inlay group (P <0.05). Conclusion: Indirect resin inlay restoration of large defects in the molar can achieve good clinical results, it is worth promoting.
