摘　　要：目的探讨改良翻瓣联合引导性骨再生(GBR)技术对上颌前牙区患者的牙槽骨宽度、软硬组织及美学效果的影响。方法回顾性分析宝鸡市第二人民医院口腔科2017年1月至2019年11月收治的80例上颌前牙区种植患者的临床资料,按照手术方式不同分为观察组和对照组各40例。对照组患者采用常规翻瓣联合GBR技术治疗,观察组患者采用改良翻瓣联合GBR技术治疗。比较两组患者术后即刻、术后1年时牙槽骨宽度、牙槽嵴顶吸收值、龈沟深度、唇侧骨厚度以及术后即刻、术后6个月、术后1年时红色美学评分(PES)的变化。结果术后1年时,观察组患者牙槽骨宽度为(3.66±0.53)mm,明显宽于对照组的(3.21±0.40)mm,牙槽嵴顶吸收值为(0.64±0.10)mm,明显低于对照组的(1.13±0.15)mm,颈部唇侧骨厚度为(4.05±0.79)mm,明显高于对照组的(3.53±0.51)mm,差异均有统计学意义(P<0.05);术后6个月、术后1年时,观察组患者PES评分分别为(11.48±1.26)分、(12.53±1.17)分,明显高于对照组的(10.53±1.22)分、(11.60±1.25)分,差异均有统计学意义(P<0.05)。结论改良翻瓣联合GBR技术在上颌前牙区患者中应用效果显著,其不仅有助于维持牙槽骨宽度,对软硬组织的影响较小,而且可提高美学效果。Objective To study the effect of modified flap operation and guided bone regeneration(GBR)technique on alveolar bone width,soft and hard tissue,and aesthetic effect in maxillary anterior region of patients.Methods The clinical data of 80 patients undergoing dental implantation in maxillary anterior region in Department of Stomatology,the Second People’s Hospital of Baoji City from January 2017 to November 2019 were retrospectively analyzed.According to different surgical methods,they were divided into an observation group and a control group,with40 patients in each group.Patients in the control group were treated with conventional flap turnover combined with GBR technique,and those in the observation group were treated with modified flap operation combined with GBR technology.The changes of alveolar bone width,alveolar crest absorption value,gingival sulcus depth,labial bone thickness at immediately and 6 months after operation,and Red Aesthetic Score(PES)at immediately,6 months and 1 year after operation were compared between the two groups.Results At 1 year after operation,the alveolar bone width in the observation group was(3.66±0.53)mm,which was significantly wider than(3.21±0.40)mm in the control group;the alveolar crest absorption value was(0.64±0.10)mm,which was significantly lower than(1.13±0.15)mm in the control group;the neck labial bone thickness was(4.05±0.79)mm,which was significantly higher than(3.53±0.51)mm in the control group;the differences were statistically significant(P<0.05).At 6 months and 1 year after operation,the PES scores in the observation group were(11.48±1.26)points,(12.53±1.17)points,which were significantly higher than(10.53±1.22)points,(11.60±1.25)points in the control group(P<0.05).Conclusion The improved flap operation combined with GBR technique have a significant effect in maxillary anterior region of patients,which can not only maintain the width of alveolar bone,but also improve the aesthetic effect.
