摘　　要：目的观察不同固位方式种植义齿修复后牙缺损对患者种植体周围组织的影响。方法选取行后牙种植单冠修复74例,共102枚种植体,根据固位方式不同将其分为观察组(37例,50枚种植体)与对照组(37例,52枚种植体)两组。观察组采用改良黏接固位种植义齿修复后牙缺损,对照组采用螺丝固位种植义齿修复后牙缺损。比较两组最后1次术后1年骨吸收量以及最后1次术后1年、2年改良菌斑指数(mPLI)分级和改良出血指数(mSBI)分级。结果术后1年,观察组近中及远中骨吸收量均低于对照组,差异有统计学意义(P<0.05)。术后1年,mPLI分级、mSBI分级0级所占比例观察组高于对照组,差异有统计学意义(P<0.05)。术后2年,mPLI分级和mSBI分级0级所占比例两组均较术后1年降低,但差异无统计学意义(P>0.05)。术后2年,mPLI分级、mSBI分级0级和1级所占比例观察组高于对照组,mPLI分级、mSBI分级2级和3级所占比例观察组低于对照组,差异有统计学意义(P<0.05或P<0.01)。结论采用改良黏接固位种植义齿修复后牙缺损效果明显,可稳定种植体骨支持,降低细菌感染,提高种植体周围组织健康程度。Objective To investigate the effect of implant prostheses with different retention methods to repair backteeth defect on the peri-implant tissues of patients. Methods Seventy-four patients(102 implants) with implant prostheses of single crown to repair backeeth defect in our hospital were selected. They were divided into observation group(37 cases, 50 implants) and control group(37 cases, 52 implants) according to different retention methods. The observation group was treated with implant prostheses by modified adhesive fixation to repair backteeth defect, and the control group was treated with implant prostheses by screw fixation to repair backteeth defect. The bone resorption in 1 year after the last operation and the modified plaque index(mPLI) classification and the modified sulcus bleeding index(mSBI) classification in 1 and 2 years after the last operation were compared between the two groups. Results In 1 year after operation, the mesiodistal bone resorption of the observation group was significantly lower than that in the control group(P<0.05). In 1 year after operation, the proportion of mPLI and mSBI grade 0 in the observation group was significantly higher than that in the control group(P<0.05). In 2 years after operation, the proportions of mPLI and mSBI grade 0 in both groups were significantly lower than those at the first year after operation, but the difference was not statistically significant(P>0.05). In 2 years after operation, the proportion of mPLI and mSBI grade 0 and 1 in the observation group was significantly higher than that in the control group, and the proportion of mPLI and mSBI grade 2 and 3 in the observation group was significantly lower than that in the control group(P<0.05 or P<0.01). Conclusion The implant prostheses by modified adhesive fixation to repair backteeth defect is effective, which can effectively stabilize the bone support of the implant, reduce bacterial infection and improve the health of peri-implant tissues.
