摘　　要：目的观察树脂充填结合多牙位冠向复位瓣技术(multiple coronally advanced flap,MCAF)治疗伴非龋性牙颈部病变(noncarious cervical lesion,NCCL)合并牙龈退缩的临床疗效.方法选取伴NCCL的多牙位牙龈退缩患者3例,使用树脂充填+MCAF,并结合上皮下结缔组织移植术(subepthelial connective tissue graft,SCTG)进行缺损区域软硬组织的修复.术后随访3年,比较手术前后的探诊深度(probing depth,PD)、出血指数(bleeding index,BI)、菌斑指数(plaque index,PLI)、退缩高度(recession height,RH)、角化龈宽度(keratinized tissue width,KTW)、牙龈厚度(gingiva thickness,GT),并计算根面覆盖美学评分(root coverage esthetic score,RES)评价术后长期随访的美学效果.结果本研究共纳入3例患者,共10个位点.PD由(1.10±0.32)mm至(1.65±0.34)mm,P=0.001;BI由0.10±0.32至0.50±0.53,P=0.037;PLI由0.30±0.48至0.40±0.52,P=0.660;10个位点均获得了100%的根面覆盖率和角化龈宽度、牙龈厚度的增加,P值分别为<0.000、0.003、<0.000.术后3年随访的RES为(9.40±0.95)分.结论树脂充填结合MCAF+SCTG技术可以修复NCCL造成的牙颈部硬组织缺损和牙龈软组织缺损,美学效果良好.Objective To observe the long-term clinical outcome of the resin restoration plus multiple coronally advanced flap technique(MCAF)for the treatment of gingival recession associated with non-carious cervical lesion(NCCL).Methods Three patients with multiple gingiva recession with NCCL were selected,and the resin restoration+MCAF combined with subepithelial connective tissue graft(SCTG)was performed to repair the soft and hard tissue'defects.Pocket depth(PD),bleeding index(BI),plaque index(PLI),recession height(RD),keratinized tissue width(KTW)and gingiva thickness(GT)were measured at baseline and follow-up 3-year after treatment and the root coverage esthetic score(RES)was calculated.Results Totally 3 patients and 10 sites were treated.The mean PD at baseline and follow-up were(1.10±0.32)mm and(1.65±0.34)mm,P=0.001.The mean BI at baseline and followup were(0.10±0.32)and(0.50±0.53)mm,P=0.037.The mean PLI at baseline and follow-up were(0.30±0.48)mm and(0.40±0.52)mm,P=0.660.All sites achieved 100%root coverage and significant augmentation of KTW and GT,and the P value was<0.000,0.003 and<0.000.The mean RES at 3-year follow-up was 9;40±0.95.Conclusion The resin restoration plus MCAF could efficiently repair the soft and hard tissue defects caused by NCCLs,and present a great esthetic outcome.
