松牙内固定远期疗效观察

A Long-term Obstervation of the Curative Effect of Internal Fixation on Loose Teeth.

目的 :重度松动的牙采用根管内—骨内种植术后的远期 (10年 )效果进行总结。方法 :对 35例 46颗因严重牙周炎 ,松动度在三度以上的单根牙行松牙内固定术 (根管内骨内种植术 )分别在 1、5、10年进行临床追踪观察并拍X线片 ,结果按疾病种类分别进行评价比较。结果 :1、5、10年复查的总有效率分别为 84.78%、47.83%、36 .96 %,其中牙周炎的 1、5、10年有效率为 87%、5 4.83%、5 1.6 1%;有牙周牙髓联合病变者分别为 80 %、33.33%、6 .6 7%。结论 :松牙内固定术可使因牙周炎而严重松动的牙恢复稳固和咀嚼功能 ,稳定牙周炎病情 ,远期观察效果良好 ,其中牙髓牙周联合病变因牙体原因远期效果稍差 ,但大多能维持 1～ 5年 ,此术安全有效可以推广。

Objective:To evaluate the long-term curative effect of internal fixation on Aeverely loose teeth.Methods:Thirty-five cases with various periodontitis over Ⅲ mobility of monoradicular teeth (46 teeth) were treated by internal fixation technic (endodontic-endosseus implantation) and reexamined periodicaly (1 year,5 years,10 years).The follow-up data were evaluated and analyged.Results:The generel effective rate of the 46 teeth was 84.78% (for 1 year),47.83%(for 5 years) and 36.96%(for 10 years) respectively,and it was 87% (1 year),54.83%(5 years),51.6%(10 years) for periodontitis teeth (31 teeth),and (15 teeth).Conclusions:The results show that the internal fixationof loose teeth may make the teeth with high grad motility recover stabilization and masticatory function.The long-term effect is good.
