摘要
目的 探讨游离龈移植和根向复位瓣术重建下颌后牙种植区角化龈的临床效果.方法 选取2015年6月~2017年12月就诊于江门市口腔医院修复科和种植科门诊的患者共计60例.采用随机数字表法将患者分为APF组和FGG组,各30例.FGG组患者给予游离龈移植术,APF组患者给予根向复位瓣术.重建角化龈.观察重建术后2个月戴牙时角化龈宽度和修复完成1年后的角化龈宽度、厚度及种植体周围垂直向骨吸收情况.结果 两组手术均获得成功,伤口正常愈合,组织瓣均存活.重建术后2、14个月的角化龈宽度、术后14个月角化龈厚度APF组分别为(3.73±0.48)mm、(3.16±0.37)mm、(1.93±0.26)mm,均低于FGG组(8.52±1.50)mm、(5.89±0.89)mm、(3.30±0.28)mm,骨吸收量APF组高于FGG组,差异均有统计学意义(P<0.05).治疗14个月后FGG组患者组织瓣水平向宽度、垂直向宽度以及表面积均低于APF组,差异有统计学意义(P<0.05).结论 根向复位瓣术和游离龈移植术可使角化龈有效增量,而游离龈移植术能够更好的恢复角化龈宽度和厚度,减少骨吸收,具有重要的临床应用价值.
Objective To explore the clinical effect of free gingival grafting(FGG)and apically repositioned flap(ARF)surgery on peri-implant keratinized gingival augmentation in posterior mandibular area.Methods A total of 60 patients treated in the outpatient department of repair and planting of Jiangmen Stomatological Hospital from June 2015 to December 2017 were selected.The patients were divided into APF group and FGG group using the random number method,with 30 cases in each group.The FGG group was given FGG,and the APF group was given ARF surgery.The keratinized gingiva was reconstructed.The keratinized gingival width when wearing teeth 2 months after reconstruction and the keratinized gingival width,thickness and vertical bone resorption around the implant one year after the restoration were observed.Results The operations in both groups were successful,the wounds healed normally,and the tissue flaps survived.The keratinized gingival width at 2 and 14 months after reconstruction and the keratinized gingival thickness at 14 months after operation in the APF group were(3.73±0.48)mm,(3.16±0.37)mm and(1.93±0.26)mm,respectively,which were lower than(8.52±1.50)mm,(5.89±0.89)mm,and(3.30±0.28)mm in the FGG group,and the bone resorption amount in the APF group was higher than that in the FGG group,and the differences were statistically significant(P<0.05).After 14 months of treatment,the horizontal width,vertical width,and surface area of the tissue flaps in the FGG group were lower than those in the APF group,and the differences were statistically significant(P<0.05).Conclusion Both ARF and FGG surgery can effectively increase the keratinized gingiva,while FGG can better restore the width and thickness of keratinized gingiva and reduce bone resorption.It is worthy of clinical application.
