摘　　要：目的分析探究3D打印个性化钛网(3D-printing individualized titanium mesh,3D-PITM)用于修复严重牙槽骨缺损的有效性及短期临床效果。方法回顾性分析2020年12月以来于广州医科大学附属口腔医院种植科接受3D-PITM联合引导骨再生(guided bone regeneration,GBR)进行牙槽骨缺损修复的15例患者为临床研究对象,观察患者术后感染、钛网暴露及主观满意度情况,同时通过数字化技术比较术后短期骨增量效果。结果15例患者均顺利完成手术,术后无出现感染,1例出现钛网暴露,钛网暴露率为6.0%。患者对手术过程、术后反应、术后复查等总体满意度(8.32±0.79)分。术后3个月平均水平骨增量为(3.02±1.52)mm,最高可到7.53 mm,平均垂直骨增量为(3.71±1.82)mm,最高可达7.30 mm。结论3D打印个性化钛网用于修复严重牙槽骨缺损,术后感染率及钛网暴露率低,患者主观满意度高,具有良好的短期临床效果,其长期稳定性有待进一步随访观察。Objective To investigate the short-term clinical effect of 3D-PITM in the restoration of severe alveolar bone defects.Methods Retrospective analysis of 15 objects who underwent the restoration of alveolar bone defeat by utilization of 3D-printing individualized titanium mesh(3D-PITM)combined with guided bone regeneration(GBR)in the Department of dental implantology of Affiliated Stomatology Hospital of Guangzhou Medical University since December 2020.Postoperative infection,3D-PITM exposure,and patient satisfaction were evaluated and short-term bone augmentation was measured by digital technique.Results A total of 15 patients was included in the current study,none of them had a postoperative infection,only one of them had 3D-PITM exposure(6.0%).Patient satisfaction on the surgery process,postoperative reaction,and follow-up was evaluated to be 8.32±0.79.In 3 months,the average acquired horizontal bone augmentation was(3.02±1.52)mm(maximum at 7.53 mm),and average acquired vertical bone augmentation was(3.71±1.82)mm(maximum at 7.30 mm).Conclusion Utilization of 3D-PITM in the restoration of severe alveolar bone defeat was promising in short-term observations with low infection and exposure rate,and high patient satisfaction outcomes.However,long-term study on bone stability by 3D-PITM is also required.
