摘　　要：目的:探讨根向复位瓣重建技术对上颌后牙种植牙颊侧角化龈的临床效果,以期为临床提供参考。方法:选取2018年12月-2020年10月本院口腔科收治的30例口腔种植修复治疗的上颌后牙单颗牙种植牙颊侧角化龈宽度<2 mm患者作为研究对象,采用随机数字表分为对照组和观察组,各15例。对照组采用传统的种植修复技术,观察组采用根向复位瓣重建技术。比较两组患者术后1周的疼痛情况,术后6个月的探诊深度及种植体牙周指数,治疗满意度。比较观察组术前,术后3、6个月的角化龈宽度、厚度。结果:术后1周,对照组NRS平均得分(2.93±0.62)分,观察组NRS平均得分(3.17±0.73)分,两组比较差异无统计学意义(P>0.05)。与对照组相比,观察组术后6个月的探诊深度、改良菌斑指数及改良龈沟出血指数都明显较低(P<0.05)。观察组术后3、6个月角化龈厚度、宽度均高于术前(P<0.05),观察组术后3、6个月角化龈厚度、宽度比较差异均无统计学意义(P>0.05)。对照组总满意度为80.00%,观察组总满意度为93.33%,两组比较差异无统计学意义(P>0.05)。结论:上颌后牙种植牙颊侧角化龈修复中应用根向复位瓣重建技术能有效改善探诊深度、改良菌斑指数及改良龈沟出血指数,在重建缺牙区角化牙龈宽度的同时改善美学效果,为种植体提供了良好的、稳定的软组织环境,修复效果良好,可作为临床优选方案。Objective:To explore the clinical effect of the apically repositioned flap reconstruction technique on keratinized gingiva of maxillary posterior implant buccal side,so as to provide reference for clinical.Method:From December 2018 to October 2020,30 patients with buccal keratinized gingival width <2 mm of single maxillary posterior dental implant underwent oral implant repair treatment were selected as the research object,who treated in stomatological department of our hospital,and they were divided into the control group and observation group according to the random number table,with 15 cases in each group.The control group adopted traditional implant repair technology,and the observation group adopted the apically repositioned flap reconstruction technique.The pain 1 week after operation,probing depth,implant periodontal index and treatment satisfaction were compared between the two groups.The width and thickness of keratinized gingival in the observation group were compared before operation and 3,6 months after operation.Result:One week after operation,the average NRS score of the control group was (2.93±0.62) points,and the average NRS score of the observation group was (3.17±0.73) points.There was no significant significance between the two groups (P>0.05).Compared with the control group,the probing depth,modified plaque index and modified gingival sulcus bleeding index were significantly lower in the observation group 6 months after operation (P<0.05).The thickness and width of the keratinized gingival in the observation group at 3 and 6 months after operation were higher than those before operation (P<0.05),and there was no significant significance in the thickness and width of the keratinized gingival in the observation group at 3 and 6 months after operation (P>0.05).The total satisfaction of the control group was 80.00%,and total satisfaction of the observation group was 93.33%,the difference between the two groups was no statistically significant (P>0.05).Conclusion:The apically repositioned flap re
