摘　　要：目的评估Er:YAG激光(erbium-doped:yttrium aluminium garnet)联合引导骨组织再生术(guided bone regeneration,GBR)治疗种植体周围炎骨缺损的临床效果。方法选择形成环形牙槽骨吸收的种植体周围牙周炎患者15例,共26颗患牙,按照随机照原则分为2组,试验组(14颗)采用Er:YAG激光联合GBR的方式治疗种植体周围骨缺损;对照组(12颗)采用机械刮治联合GBR治疗牙槽骨的缺损。在基线和6个月时进行临床牙周指标的检查测定,包括菌斑指数(plaque index,PI)、龈沟出血指数(sulcus bleeding index,SBI)、牙周探诊深度(probing depth,PD)及临床附着丧失(clinical attachment lost,CAL),并进行比较。结果 2组术后PI、SBI、PD及CAL均较术前有明显改善(P<0.05)。术后2组PI均值都维持在一个较低的水平,差异无统计学意义(P>0.05);试验组与对照组的SBI分别为(0.8±0.2)、(1.1±0.2);PD分别为(5.8±0.8)mm、(6.2±0.6)mm;CAL分别为(2.3±0.7)mm、(3.6±0.6)mm。组间比较差异均有统计学意义(P<0.05)。结论 Er:YAG激光联合GBR在治疗种植体周炎骨缺损具有较好的临床效果。Objective To evaluate the therapeutic effects of erbiumdoped:yttrium aluminium garnet laser(Er:YAG laser)combined with guided bone regeneration(GBR)in the treatment of periimplantitis bone defect.MethodsA total of26implants in15patients with periimplantitis were selected and divided into experimental group(14implants)and control group(12implants)randomly.The experimental group was treated with Er:YAG laser combinedwith GBR,and the control group was treated with mechanical curettage with GBR.Clinical periodontal index test including plaque index(PI),sulcus bleeding index(SBI),probing depth(PD)and clinical attachment level(CAL)werechecked at baseline,3months and6months.All the above data were statistically analyzed.Results All of the clinicalperiodontal index were improved after surgery.SBI,PD and CAL of the experimental group was0.8±0.2mm,5.8±0.8mm,and2.3±0.7mm,while they were1.1±0.2mm,6.2±0.6mm,and3.6±0.6mm in the control group.The experimental group showed better results than the control group(P<0.05),while PI showed no difference between the2groups(P>0.05).Conclusion The combined application of Er:YAG laser and GBR in the treatment of bone defectin peri-implantitis has good clinical effects.
