个性化钛网联合屏障膜对上前牙骨缺损患者GBR修复效果及PES评分的影响

The Effect of Personalized Titanium Mesh Combined with Barrier Membrane in GBRRepair for Patients with Upper Anterior Teeth Bone Defects and Its Impact on PESScore

目的:探讨个性化钛网联合屏障膜对上前牙骨缺损患者引导骨再生(Guided bone regeneration,GBR)修复效果及红色美学指数(Pink esthetic score,PES)评分的影响。方法:回顾性分析2020年12月-2022年5月笔者医院就诊的208例上前牙牙槽骨缺损患者病例资料,患者均行GBR术,根据术中应用膜材料的不同分成屏障膜组(103例)和复合组(105例)。屏障膜组术中使用屏障膜,复合组在屏障膜组基础上联合个性化钛网。了解患者牙槽骨宽度及高度变化,评定患者PES评分,同时观察并发症发生情况。结果:术后当日、6个月,两组牙槽骨宽度及高度均大于术前(P<0.05),两组术后6个月牙槽骨宽度及高度均较术后当日有所减小(P<0.05),复合组术后6个月牙槽骨宽度及高度均大于屏障膜组(P<0.05);术后3个月、6个月,两组PES评分均低于术后当日(P<0.05),两组术后6个月PES评分均较术后3个月降低(P<0.05),但复合组术后6个月PES评分高于屏障膜组(P<0.05);复合组并发症发生率(3.81%)和屏障膜组(5.83%)比较差异无统计学意义(P>0.05)。结论:在上前牙骨缺损患者GBR术中使用个性化钛网联合屏障膜,对骨缺损的修复效果较好,有利于提高牙龈美观效果,且安全性高。

Objective To explore the effect of personalized titanium mesh combined with barrier membrane in guided bone regeneration(GBR)repair for patients with upper anterior teeth bone defects,and its impact on the Pink Esthetic Score(PES)score.Methods A retrospective analysis was conducted on the data of 208 patients with alveolar bone defects in the upper anterior teeth selected by the author's hospital from December 2020 to May 2022.All patients underwent GBR surgery and were grouped into a barrier membrane group(103 cases)and a composite group(105 cases)based on the different membrane materials used during the surgery.The barrier membrane group used a barrier membrane during surgery,while the composite group used a personalized titanium mesh on the basis of the barrier membrane group.The width and height changes of the patient's alveolar bone were understood,the PES score was evaluated,and the occurrence of complications was observed.Results On the day and 6 months after surgery,the width and height of alveolar bone in both groups were greater than before surgery(P<0.05),the width and height of alveolar bone in both groups decreased at 6 months after surgery compared to the day after surgery(P<0.05),while the width and height of alveolar bone in the composite group were greater than those in the barrier membrane group at 6 months after surgery(P<0.05).At 3 and 6 months after surgery,the PES score of both groups was lower than the day after surgery(P<0.05),the PES score of both groups at 6 months after surgery was lower than that at 3 months after surgery(P<0.05),the PES score of the composite group at 6 months after surgery was higher than that of the barrier membrane group(P<0.05).There was no statistically obvious difference in the incidence of complications between the composite group(3.81%)and the barrier membrane group(5.83%)(P>0.05).Conclusion The use of personalized titanium mesh combined with barrier membrane in GBR surgery for patients with upper anterior tooth bone defects has a good repair effect on bone defects,is beneficial for improving gingival aesthetics,and has high safety.
