The coronally advanced flap has been documented as an effective surgical technique for the treatment of gingival recessions in cases of multiple adjacent recession defects, obtaining stable long-term results after 5 years of follow-up. The aim of the present study was to test the coronally advanced flap, in association with a connective tissue graft, in a case series of 10 patients presenting at least two gingival recessions on adjacent teeth in the posterior mandibular area. Periodontal parameters were recorded on teeth involved in the surgeries at baseline and 1 year. A total of 26 recessions were treated. No significant complication affected the surgeries, and no patient abandoned the study. Recession depth was reduced from 3.40 ± 0.83 mm at baseline to 0.28 ± 0.32 mm at the 1-year control, while differences in pocket depth were not significant. Keratinized tissue increased from 0.57 ± 0.46 mm to 3.05 ± 0.71 mm. Greater reductions in recession depth were observed in cases where the initial conditions were worse. A mean 91.2% ± 4.1% recession coverage was obtained. The coronally advanced flap in association with a connective tissue graft can be proposed as a valid therapeutic approach for multiple recession defects in mandibular posterior areas.
在多相邻退缩缺损病例中，冠向推进瓣已被证明是一种治疗牙龈退缩的有效手术技术，在5年随访后可获得稳定的长期效果。本研究的目的是在一组10例下颌后牙区相邻牙齿至少有两处牙龈退缩的病例系列中，测试冠向推进瓣联合结缔组织移植的效果。在手术涉及的牙齿上，于基线和1年时记录牙周参数。共治疗了26处退缩。手术未出现明显并发症，也没有患者退出研究。退缩深度从基线时的3.40±0.83毫米降至1年复查时的0.28±0.32毫米，而牙周袋深度差异不显著。角化组织从0.57±0.46毫米增加到3.05±0.71毫米。初始情况较差的病例中，退缩深度的减少更为明显。平均退缩覆盖率为91.2%±4.1%。冠向推进瓣联合结缔组织移植可作为下颌后牙区多个退缩缺损的一种有效治疗方法。
