摘　　要：目的:分析预成型钛网联合胶原膜及富血小板纤维蛋白(Platelet-rich fibrin,PRF)在前牙牙槽嵴严重骨缺损种植中的应用效果。方法:选取2021年1月-2021年12月青岛市市立医院西院区收治的202例前牙牙槽嵴严重骨缺损患者,按随机数字表法分为两组。对照组101例,采用预成型钛网联合胶原膜治疗;观察组101例,采用预成型钛网联合胶原膜及PRF治疗。比较两组治疗后不同时间点牙槽骨形态变化、牙周指标、美学指标及并发症发生情况。结果:治疗后6个月、12个月,观察组牙槽骨量体积增加值、高度增加值及宽度增加值均高于对照组(P<0.05);种植修复后6个月,两组种植体周围菌斑指数(Plaque index,PLI)、牙龈指数(Gingival index,GI)及探诊深度(Probing depth,PD)比较,差异无统计学意义(P>0.05);治疗后6个月,观察组红色美学指数(Pink ethetic score,PES)高于对照组(P<0.05),治疗后12个月,两组PES评分比较差异无统计学意义(P>0.05);两组并发症发生率比较,差异无统计学意义(P>0.05)。结论:预成型钛网联合胶原膜及PRF在前牙牙槽嵴严重骨缺损种植中的应用效果确切,能促进牙槽骨形成,提供稳定的种植体环境,提高美学效果,安全性良好。Objective To evaluate the application effect of preformed titanium mesh combined with collagen membrane and platelet-rich fibrin(PRF)in patients with severe bone defects of anterior alveolar ridge.Methods A total of 202 patients with severe bone defects of anterior alveolar ridge admitted to West Branch of Qingdao Municipal Hospital were enrolled between January and December 2021.According to random number table method,they were divided into control group(101 cases,preformed titanium mesh combined with collagen membrane)and observation group(101 cases,PRF on basis of control group).The morphological changes of alveolar bone after treatment,periodontal indexes,aesthetic indexes and complications were compared between the two groups.Results At 6 and 12 months after treatment,increments of alveolar bone volume,height and width in observation group were greater than those in control group(P<0.05).At 6 months after implant restoration,there was no significant difference in plaque index(PLI),gingival index(GI)or probing depth(PD)between the two groups(P>0.05).At 6 months after treatment,Pink ethetic score(PES)in observation group was higher than that in control group(P<0.05),but there was no significant difference between the two groups at 12 months after treatment(P>0.05).There was no significant difference in incidence of complications between the two groups(P>0.05).Conclusion Application effect of preformed titanium mesh combined with collagen membrane and PRF is significant in patients with severe bone defects of anterior alveolar ridge,which can promote alveolar bone formation,provide a stable implant environment and improve aesthetic effect,with good safety.
