铸造纯钛环修复龈下残根的临床疗效评价

Evaluation of clinical efficacy of casting pure titanium ring on reparation of subgingival residual root

目的:探讨铸造纯钛环对龈下残根修复的治疗方案和疗效。方法:选择2008—2010在我科收冶的32例经过完善根管治疗后龈下残根的病例,采用铸造纯钛环+玻璃纤维桩+全瓷冠修复,于修复前和修复后12个月及24个月分别进行常规牙龈指数检查、龈沟液量检测,采用SPSS 17.0软件包对数据进行配对t检验。结果:患者的牙龈指数、龈沟液量在修复前、修复后12个月和24个月均无显著变化(P>0.05)。结论:在合适的病例中,采用铸造纯钛环修复龈下残根,大多数患牙仍能发挥良好功能。

PURPOSE： To explore treatment regime and curative effect of the casting pure titanium ring on reparation of subgingival residual root. METHODS： Thirty-two teeth were selected for reparation of subgingival residual root after root canal therapy in our department during 2008-2010. The teeth were restored with casting pure titanium ring, glass fiber post and all-ceramic crown. The patients were recalled 12 and 24 months after placement of the pure titanium ring. Gingival crevicular fluid（GCF）samples were collected by filter paper strips . Then the weight of GCF was detected and the gingival index was recorded. The data was analyzed for paired samples t test by SPSS17.0 software package. RESULTS： There was no significant difference in the weight of GCF and the gingival index before and after placement of pure titanium ring （P〉0.05）. CONCLUSIONS： By using pure titanium ring, most subgingival residual root after root canal therapy can be rehabilitated and function well for long time.
