摘要目的 分析不翻瓣技术在前牙美观区即刻种植修复中的应用价值.方法 选择嘉兴市第一医院口腔科2016 年3 月至2017 年9 月行前牙即刻种植修复的患者104 例,采用随机数字表法分为观察组53例、对照组51例.对照组采用常规翻瓣即刻种植术,观察组采用不翻瓣即刻种植术,比较两组修复后红色美学指数(EPS)、牙槽骨吸收量及患者满意度.结果 修复后3个月、6个月、12个月,观察组PES评分分别为(6.17 ± 1.21)分、(5.94 ± 1.03)分、(5.12 ± 0.85)分,均高于对照组的(5.38 ± 0.96)分、(4.79 ± 0.76)分、(4.05 ± 0.70)分(t=3.679、6.459、6.993,均P<0.05).修复后3个月、6个月、12个月,观察组牙槽骨吸收量分别为(0.29 ± 0.04)mm、(0.63 ± 0.12)mm、(1.07 ± 0.17)mm,均低于对照组的(0.36 ± 0.07)mm、(0.95 ± 0.24)mm、(1.28 ± 0.26)mm(t=6.291、8.649、4.893,均P<0.05).修复后12 个月,观察组患者满意度为98.11％(52/53),显著高于对照组的84.31％(43/51)(χ2 =4.637,P<0.05).结论 不翻瓣技术在前牙美观区即刻种植修复中应用效果良好,可获得更佳的美学效果,减少牙槽骨吸收,提高患者对修复的满意度.

abstractsObjective To explore the application value of non－flapping technique in immediate implant prosthesis in aesthetic area of anterior teeth.Methods From March 2016 to September 2017,104 patients who received immediate implant restoration of anterior teeth in the First Hospital of Jiaxing were divided into observation group(53 cases)and control group(51 cases)according to random number table method.The control group was treated with conventional flap immediate implantation,while the observation group was treated with non－flap immediate implantation.The red aesthetic index(EPS),alveolar bone resorption and patients' satisfaction were compared between the two groups.Results The PES scores of the observation group were(6.17 ± 1.21)points,(5.94 ± 1.03)points and(5.12 ± 0.85)points,respectively after repair 3 months,6 months and 12 months,which were signif-icantly higher than those of the control group [(5.38 ± 0.96)points,(4.79 ± 0.76)points,(4.05 ± 0.70)points](t=3.679,6.459,6.993,all P<0.05).At 3 months,6 months and 12 months after restoration,the alveolar bone resorption in the observation group was(0.29 ± 0.04)mm,(0.63 ± 0.12)mm,(1.07 ± 0.17)mm,respectively,which was significantly lower than that in the control group [(0.36 ± 0.07)mm,(0.95 ± 0.24)mm,(1.28 ± 0.26)mm](t=6.291,8.649,4.893,all P<0.05).At 12 months after repair,the satisfaction rate of patients in the observation group was 98.11％(52/53),which was significantly higher than 84.31％(43/51)in the control group(χ2 =4.637,P<0.05).Conclusion The application of non－flapping technique in immediate implant prostheses in aesthetic area of anterior teeth has good effect,which can obtain better aesthetic effect,reduce alveolar bone absorption and improve patients'satisfaction with prostheses.However,in clinical work,it is necessary to strengthen preoperative examination and measurement of patients,accurately grasp the direction of implants and avoid the occurrence of bone wall perforation during operation.
