摘要
目的探讨帐篷钉技术在前牙美学区连续缺失种植修复中的临床应用效果。方法选取2019年12月至2023年12月于杭州口腔医院城西分院种植中心接受治疗的86例前牙美学区连续缺失种植患者,根据骨增量术式及种植时机的不同分为试验组(帐篷钉技术+延期种植)和对照组(常规引导骨再生+即刻种植),每组43例。收集患者骨增量前、骨增量后6个月和12个月、种植体植入后及最终修复后1~12个月的锥形束计算机体层成像(CBCT)影像资料。对比2组种植体留存率;基于CBCT影像,测量2组患者骨增量后6个月和12个月时牙槽嵴顶处的牙槽骨宽度;并参考红色美学评分(PES),评估患者修复即刻、最终修复后6个月和12个月种植修复体的美学状况,比较2组差异。结果对照组种植体留存率为98.21%,试验组为100.00%。试验组在骨增量后6个月和12个月时牙槽嵴顶处的牙槽骨宽度分别为(7.69±0.42)mm和(7.22±0.40)mm,均高于对照组的(6.53±0.39)mm和(6.20±0.43)mm(P=0.001)。试验组在最终修复后6个月和12个月时的PES分别为(10.72±1.42)分和(9.95±1.34)分,均高于对照组的(7.52±1.20)分和(7.01±1.15)分(P=0.001)。结论帐篷钉技术在前牙美学区连续缺失种植修复中能有效保障种植体的留存率,其效果与引导骨再生相当。在前牙美学区连续缺失种植修复病例中,帐篷钉技术可实现更佳的骨增量效果和美学修复效果。
Objective To use a retrospective clinical approach to analyze the clinical treatment effects of screw tenting technology in implant restoration of consecutively missing teeth in the anterior esthetic zone.Methods A total of 86 patients with consecutive anterior teeth esthetic area defects who were treated at the Implant Center of the West City Branch of Hangzhou Stomatology Hospital from December 2019 to December 2023 were included.They were divided into the experimental group(tenting screw technique+delayed implantation)and the control group(conventional guided bone regeneration technique+immediate implantation),with 43 cases in each group.Cone beam computed tomography(CBCT)imaging data of patients were collected at the following time points:before bone augmentation,6 months,and 12 months after bone augmentation,after implant placement,and 1 to 12 months after final restoration.The implant survival rate of the two groups was compared.Based on CBCT digital imaging data,the alveolar bone width at the alveolar ridge crest of the two groups of patients 6 months and 12 months after bone augmentation was measured respectively.Meanwhile,the esthetic status of the implant restorations immediately after restoration,6 months after restoration,and 12 months after restoration was evaluated using the pink esthetic score,and the differences between the two groups were compared.Results The implant survival rate was 98.21%in the control group and 100.00%in the experimental group.The alveolar bone width at the alveolar ridge crest in the experimental group was higher than that in the control group at 6 months and 12 months after bone augmentation,with values of(7.69±0.42)mm and(7.22±0.40)mm in the experimental group,and(6.53±0.39)mm and(6.20±0.43)mm in the control group(P=0.001).The pink esthetic score(PES)of the experimental group was higher than that of the control group at 6 months and 12 months after the final restoration,with scores of(10.72±1.42)and(9.95±1.34)in the experimental group,and(7.52±1.20)and(7.01±1.15)in the control group(P=0.001).Conclusion The tenting screw technique can effectively ensure the survival rate of implants in the implant restoration of consecutive anterior teeth esthetic area defects.Its implantation effect is comparable to that of the guided bone regeneration(GBR)technique.In the implant restoration cases of consecutive anterior teeth esthetic area defects,the tenting screw technique can achieve better bone augmentation and restoration effects.
