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。
Objective: To investigate the treatment and efficacy of casting pure titanium rings for the repair of subgingival residual roots. Methods: The cases of subgingival root remnant after perfecting root canal treatment of 32 cases received in our department from 2008 to 2010 were selected. The specimens were cast with pure titanium ring and fiberglass piles + all-ceramic crowns. Before and after repair, 12 Month and 24 months, respectively, the conventional gingival index test, gingival crevicular fluid test, the data using SPSS 17.0 package paired t test. Results: There was no significant change in gingival index and gingival crevicular fluid volume between 12 and 24 months after repair in both groups (P> 0.05). CONCLUSIONS: In appropriate cases, a cast titanium ring is used to repair subgingival residual roots, and most of the affected teeth still perform well.
