二甲双胍对有运动习惯的T2DM患者种植体边缘骨吸收的影响

The impact of metformin on marginal bone loss at the edge of implants in patients with type 2 diabetes mellitus and exercise habit

目的:回顾性研究二甲双胍对有运动习惯的2型糖尿病(T2DM)患者种植体的边缘骨吸收的影响。方法:纳入行下颌第一磨牙区不植骨手术的病例63例,种植73枚。种植修复完成后6月、1年和2年复诊检查,比较正常血糖对照组(N组41例47枚种植体)、2型糖尿病服用二甲双胍无运动习惯(M组10例13枚种植体)、2型糖尿病服用二甲双胍有运动习惯(MR组12例12枚种植体)3组间的边缘骨吸收(MBL)、种植体成功率和种植体周围炎发病率。结果:N组和MR组的远期骨水平种植体近中边缘骨吸收显著低于M组(分别为P=0.001,P=0.0005);N组、MR组与M组的种植体成功率分别为95.74%、100%、76.92%;种植体周围炎发病率分别为2.13%、0和15.38%。结论:在下颌第一磨牙区不植骨的种植手术中,2型糖尿病有运动习惯的患者服用二甲双胍可改善其种植体的远期边缘骨吸收,提高种植体成功率,降低种植体周围炎发病率,预后优于无运动习惯者。

Objective:To study the effects of metformin on marginal bone resorption of implants in patients with type 2 diabetes mellitus(T2DM)and exercise habit.Methods:63 cases with 73 implants were included.Among them,there were 41 cases(47 implants)without T2DM in group N,10 cases(13 implants)with T2DM and without exercise habit in group M,12 cases(12 implants)with T2DM and exercise habit in the MR group.The patients were followed up at 6 months,1 and 2 years after implantation.The marginal bone loss(MBL).Implantation success rate and peri-implantitis incidence rate were compared among the groups.Results:The bone resorption of the proximal and median margins of the long-term bone level of the implants in the N and MR groups were significantly lower than that in the M group(P=0.001 and P=0.0005,respectively).The implant success rates of group N,MR and M were 95.74%,100%and 76.92%,respectively.The incidence of peri-implantitis of the three groups was 2.13%,0 and 15.38%,respectively.Conclusion:Metformin is more effective in the improvement of the long-term marginal bone resorption of implants,increase the success rate of implants,and reduce the incidence of peri-implantitis in patients with T2DM and exercise habit in the mandibular first molar area.
