In the mandibular anterior area, gingival recession can be associated with a minimal amount or lack of attached gingiva, a shallow vestibule, and high frenum insertion. These anatomical features may preclude the use of traditional root coverage procedures. This case series describes a a bilaminar technique with flap incision in the fornix for the treatment of adjacent gingival recession defects in patients with a shallow vestibule. It achieved high predictability in complete root coverage without decreasing the vestibular depth. At 24 months, the treatment resulted in 90.6% ±16.8% root coverage, and 11 of the 15 treated teeth (73.3%) were completely covered.
在下颌前部区域，牙龈退缩可能与附着龈量极少或缺乏、前庭浅以及系带附着位置高有关。这些解剖特征可能使传统的牙根覆盖手术无法实施。本病例系列描述了一种在穹窿处进行瓣切口的双层技术，用于治疗前庭浅的患者相邻牙龈退缩缺损。该技术在完全牙根覆盖方面具有很高的可预测性，且不会减小前庭深度。在24个月时，治疗实现了90.6%±16.8%的牙根覆盖，15颗治疗牙中有11颗（73.3%）完全被覆盖。
