即刻种植在根管治疗失败病例中的应用

The application of immediate implant placement in failure of root canal therapy cases

目的:探讨即刻种植在根管治疗失败病例中的应用。方法:选择2014年1月到2017年12月来就诊的64名患者,根管治疗失败后能够接受种植修复,共植入66枚种植体,其中采用即拔即种方法共32枚种植体,设为实验组;另外拔牙后3个月以上常规植入34枚种植体,设为对照组。比较两组负重1年的存留率;种植体周菌斑指数(PLI)、种植体周改良出血指数(mBI)、探诊深度(PD)。数据用PASW statistic 20.0软件进行统计学分析。结果:两组负重1年存留率为100%;两组种植体周围PLI、mBI、PD比较,无显著性差异。结论:对于根管治疗失败病例,患牙即拔即种是一种可行性高的修复方式。

Objective:To explore the application of immediate implant placement in root canal therapy failure cases.Methods:64 patients who came from January 2014 to December 2017 were selected.After root canal treatment failed,66 implants were implanted.The 32 implants were implanted by immediate implant method,and 34 implants were implanted routinely at least three months after extraction as control group.The 1-year survival rate,peri-implant plaque index(PLI),modified peri-implant hemorrhage index(mBI)and probing depth(PD)of the two groups were compared.The data were analyzed by PASW statistic 20.0 software.Result:The 1-year survival rate of weight-bearing in the two groups was 100%.There was no significant difference in PLI,mBI and PD around implants between the two groups.Conclusion:For root canal treatment failure cases,immediate implant is a feasible way of restoration.
