摘　　要：目的:评价重度牙周炎磨牙进行微创拔牙和微翻瓣位点保存术后植体负重1年的效果。方法:纳入2015年1月~2017年1月于牙周科就诊的18名患者共20颗磨牙,种植修复后负重1个月(基线)和12个月对种植牙进行临床检查,记录菌斑指数(silness&leo plaque index,PLI)、植体周软组织探诊深度(peri-implant probing depth,PPD)、出血指数(mazza bleeding index,BI)、颊侧角化组织宽度(width of keratinized tissue,KTW);基线和负重1年拍摄平行投照根尖片测量边缘骨丧失(marginal bone loss,MBL)。结果:20颗种植修复体负重1年后存留率和成功率为100%。负重即刻和负重1年PLI、PPD、BI、KTW变化均无统计学差异(P>0.05),MBL为(0.12±0.24)mm。结论:微翻瓣位点保存术后种植修复负重1年获得了良好的临床效果。Objective:To evaluate the effects of implants following minimally invasive extraction and minimal flap in ridge preservation at molar extraction sockets with severe periodontitis after 1 year load.Methods:Eighteen patients with a total of 20 molar extraction sockets were recruited in the study from January 2015 to January 2017.At 1-month(baseline)and 1-year post-load,each implant was examined with the following parameters:plaque index(Silness&Leo Plaque Index,PLI),peri-implant probing depth(PPD),bleeding index(Mazza,BI),and width of keratinized tissue(KTW).Parallel periapical radiographs were taken at baseline and 1-year post-load to evaluate the peri-implant marginal bone loss(MBL).Results:The survival rate and success rate were 100%for 20 implants.There were no statistically significant differences in the PLI,PPD,BI,and KTW between baseline and 1-year post-load(P>0.05).MBL was(0.12±0.24)mm(P>0.05).Conclusion:The clinical outcomes of implant restoration were favorable following minimal flap and ridge preservation at molar extraction sockets with severe periodontitis after 1-year load.
