摘要
目的 ：探讨Benex微创拔牙技术在前牙不翻瓣即刻种植中的技术要点,并评价其临床效果。方法 ：25例无法保留、需要拔除并具备即刻种植适应证的上前牙残根患者,接受Benex微创拔牙不翻瓣即刻种植。种植体植入同期安装愈合基台,4~6个月后行纵向螺钉固定,暂时冠修复,进行软组织塑形,3个月后完成永久修复。记录拔牙所需时间并应用视觉模拟评估量表（VAS）评估该方法的难易程度。影像学检查评估种植术后即刻及种植修复后1年种植体骨结合及边缘骨吸收。根据改良软组织美学指数（PES）评价拔牙术前及修复1年后的牙龈美学效果。采用SPSS13.0软件包对数据进行统计学分析。结果：25颗种植体均获得良好的骨结合,随访期间无种植体脱落,修复后1年种植体边缘骨吸收（0.21±0.23）mm。拔牙后PES为8.8±1.19,与拔牙前相比,差异无显著性（P〉0.05）。拔牙平均需时6.87 min,操作相对简便,VAS值为3.32。所有患者对拔牙过程及修复效果满意。结论：Benex微创拔牙技术操作简单,适用于上颌前牙不翻瓣即刻种植,对软、硬组织无损伤,患者对治疗过程及种植修复效果满意。
PURPOSE： To evaluate the feasibility and clinical outcomes of an atraumatic extraction technique using Benex Extraction System in flapless immediate implant placement in anterior teeth. METHODS： Twenty-five patients with single hopeless anterior maxillary teeth were enrolled in the study. The involved teeth were extracted using Benex Extraction System and implants were immediately placed in a flapless way. Healing abutments were connected immediately. After 4-6 months of healing, screw-retained implant temporary crowns were used to reshape the peri-implant gingiva. Permanent restorations were delivered 3 months later. Extraction time was recorded and the technique feasibility was evaluated using visual analogue scale（VAS）. Peri-implant marginal bone resorption was measured in X- ray films after loading for 1 year later. Pink esthetic score（PES） was checked to evaluate the gingival esthetics. Questionnaire was delivered and collected to assess patients＇ satisfaction on surgical experience and esthetic outcomes. SPSS 13.0 software package was used for statistical analysis. RESULTS： Twenty-five implants osseointegrated successfully. The marginal bone resorption was（0.21±0.23） mm and PES was 8.8±1.19 after loading for 1 year. The mean extraction time was 6.87 minutes and the VAS was 3.32. All patients were satisfied with the final esthetic outcomes and felt comfort during surgery.CONCLUSIONS： According to the limited data in the study, Benex extraction System is a convenient, atraumatic and predictable technique during flapless immediate implant placement in anterior teeth.
