To compare the percentage of mean root coverage (MRC%) obtained in the treatment of multiple Miller class III/RT2 gingival recessions using the modified VISTA (m-VISTA) technique versus the coronally advanced flap (CAF) technique, using a connective tissue graft (CTG) in both cases.
Twenty-four patients were randomly treated with m-VISTA (test group (TG) = 12) or CAF (control group (CG) = 12). A calibrated, experienced, and blinded examiner collected data related to multiple periodontal clinical variables, especially the recession (REC) in order to calculate the MRC% at 6 and 12 months, which was the primary outcome of the study. Also, the radiological bone level, the characteristics of the CTG, and postsurgical incidences were assessed. Finally, a descriptive and an analytical statistical analysis of the variables and their associations was performed.
The recessions (n = 84) were located mainly in the mandible (n = 65) and in posterior sectors (premolars: n = 35; molars: n = 8). At 6 months, the MRC% was 61% (2 mm) for both study groups, and at 12 months, it increased to 73.26% (2.11 mm) in the TG and decreased to 56.49% (1.78 mm) in the CG.
When approaching multiple Miller class III/RT2 recessions, there were no statistically significant differences in the MRC% at 6 and 12 months between the group treated with the m-VISTA technique and the group treated with the CAF.
The characteristics of the m-VISTA technique, such as the closed approach, the mobilization of the papilla, and the coronal stabilization of the CTG, could facilitate the maturation of the tissues in the treatment of Miller class III/RT2 recessions. This would favor better root coverage.

比较改良 VISTA（m-VISTA）技术与冠向推进瓣（CAF）技术联合使用结缔组织移植物（CTG）治疗多发性 Miller Ⅲ类/RT2 牙龈退缩时的平均根面覆盖率（MRC%）百分比，在两种情况下均使用 CAF。
24 名患者被随机分为 m-VISTA 组（试验组（TG）=12 例）或 CAF 组（对照组（CG）=12 例）。一位经过校准、有经验且盲法的检查者收集了与多项牙周临床变量相关的数据，特别是为了计算 6 个月和 12 个月时的 MRC%而进行的退缩（REC），这是该研究的主要结果。此外，还评估了影像学骨水平、CTG 的特征和术后并发症。最后，对变量及其相关性进行了描述性和分析性统计分析。
84 个退缩（n=84）主要位于下颌（n=65）和后牙区（前磨牙：n=35；磨牙：n=8）。6 个月时，两组的 MRC%均为 61%（2mm），12 个月时，TG 增加至 73.26%（2.11mm），CG 则减少至 56.49%（1.78mm）。
在治疗多发性 Miller Ⅲ类/RT2 退缩时，m-VISTA 技术组与 CAF 技术组在 6 个月和 12 个月时的 MRC%无统计学差异。
m-VISTA 技术的特点，如封闭方法、乳头移动和 CTG 的冠向稳定，可能有助于 III 类/RT2 退缩的组织成熟，从而更好地实现根面覆盖。
