摘　　要：背景:有研究将富血小板纤维蛋白与自体骨联合应用于牙周骨缺损治疗取得了良好效果,但二者联合治疗牙槽骨重度缺损的研究目前较为匮乏。目的:观察自体骨移植与富血小板纤维蛋白联合修复牙槽骨重度缺损的效果。方法:选择2022年4月至2023年2月衡水市人民医院收治的102例牙槽骨重度缺损患者,采取随机数字表法分为对照组(n=51)与观察组(n=51),两组患者均进行引导性组织再生手术,对照组术中采用自体骨填充骨缺损,观察组术中采用自体富血小板纤维蛋白与自体骨填充骨缺损。观察两组临床疗效、手术前后牙齿松动度、牙周微生态环境(探诊深度、临床附着丧失、出血指数)、牙槽骨高度及密度、龈沟液指标(转化生长因子β、丝氨酸蛋白酶抑制剂、基质金属蛋白酶3)变化及不良反应情况。结果与结论:术后6个月,两组治疗有效率比较差异无显著性意义(P> 0.05);观察组患者术后3,6个月的牙齿松动度及牙周探诊深度、临床附着丧失、出血指数均低于对照组(P <0.05),术后6个月的牙槽骨高度高于对照组(P <0.05),术后3,6个月的龈沟液转化生长因子β水平高于对照组(P <0.05),术后3,6个月的龈沟液丝氨酸蛋白酶抑制剂、基质金属蛋白酶3水平均低于对照组(P <0.05)。结果提示:在引导性组织再生手术中,采用自体富血小板纤维蛋白与自体骨联合填充可改善牙槽骨重度缺损患者的牙周微生态环境、减轻牙龈组织炎症、促进牙槽骨组织再生与修复、降低牙齿松动度。BACKGROUND:The combination of platelet-rich fibrin and autogenous bone has achieved good results in the treatment of periodontal bone defects,but the study of the combination of the two in the treatment of severe alveolar bone defects is scarce.OBJECTIVE:To observe the effect of autologous bone transplantation plus platelet-rich fibrin on the repair of severe alveolar bone defects.METHODS:A total of 102 patients with severe alveolar bone defects in Hengshui People’s Hospital from April 2022 to February 2023 were selected and divided into control and observation groups(n=51 per group)by random number table method.Guided tissue regeneration was performed in both groups.The bone defect was filled with autogenous bone in the control group,and the observation group underwent platelet-rich fibrin+autogenous bone filling for bone defects during the operation.The clinical efficacy,changes in tooth mobility,periodontal microecological environment(probing depth,clinical attachment loss,and bleeding index),height and density of alveolar bone,gingival crevicular fluid indicators(transforming growth factor-β,serine protease inhibitor,and matrix metalloproteinase-3)before and after surgery,as well as adverse reactions were observed between the two groups.RESULTS AND CONCLUSION:Six months after operation,there was no significant difference in treatment efficacy rate between the two groups(P>0.05).At 3 and 6 months after surgery,the levels of tooth mobility,probing depth,clinical attachment loss,and bleeding index in the observation group were lower than those in the control group(P<0.05).At 6 months after surgery,the height of alveolar bone in the observation group was higher than that in the control group(P<0.05).At 3 and 6 months after surgery,the levels of transforming growth factor-βin gingival crevicular fluid in the observation group were higher than those in the control group(P<0.05).At 3 and 6 months after surgery,the levels of serine protease inhibitor and matrix metalloproteinase-3 in the observation group were lo
