One of the main objectives of root coverage procedures is complete coverage of the denuded root surface. If this goal is not obtained, retreatment may be considered. This retrospective case series study evaluated the need for surgical retreatment among 105 gingival recessions, in 56 patients. Pre- and postretreatment recession depth (RD), keratinized tissue (KT) width, and attachment loss (AL) were extracted from follow-up registries. A total of 17 recessions (11 Miller Class I-II/RT1 and 6 Miller Class III/RT2) in 13 patients (nine and four, respectively) were retreated surgically. The mean follow-up was 2.2 years (range 1-9). RD and the clinical attachment level gain (CAL gain) improved significantly after retreatment (=0.0017). The linear regression model revealed a significantly higher KT gain (KTG) and reduction in residual RD (RRD), in patients with initial Miller III/RT2 recessions, when followed up for more than 1 year ( < 0.0001). The present results indicate that a root recession retreatment procedure is a viable option with high predictability and long-term stability.
根面覆盖术的主要目标之一是完全覆盖暴露的根面。如果未实现这一目标，则可考虑再次治疗。本回顾性病例系列研究评估了56例患者105处牙龈退缩的手术再次治疗需求。从随访记录中提取治疗前后的退缩深度（RD）、角化组织（KT）宽度和附着丧失（AL）。13例患者（分别为9例和4例）共17处退缩（11处米勒I-II类/RT1和6处米勒III类/RT2）接受了手术再次治疗。平均随访时间为2.2年（范围1-9年）。再次治疗后，RD和临床附着水平增加（CAL增加）有显著改善（=0.0017）。线性回归模型显示，初始为米勒III/RT2类退缩的患者，随访超过1年时，KT增加（KTG）和残余RD减少（RRD）显著更高（<0.0001）。目前的结果表明，根面退缩再次治疗程序是一种具有高可预测性和长期稳定性的可行选择。
