Five patients with buccal gingival recession (4 to 6 mm) underwent surgical treatment consisting of a guided tissue regeneration procedure associated with a free gingival graft. The graft was used to cover the newly formed tissue on the root surface at the reentry. Root coverage was complete in three patients, while 1 mm of recession remained in the other two patients. The free gingival graft reconstructed the keratinized tissue, which had been lost because of recession. Moreover, it allowed the mucogingival junction, which had been displaced coronally during the first surgery, to be realigned, therefore preventing a shallowing of the vestibule.
5例颊侧牙龈退缩（4至6毫米）患者接受了手术治疗，该手术包括引导组织再生程序联合游离龈瓣移植术。移植瓣用于在再次翻开时覆盖根面上新形成的组织。3例患者实现了完全的牙根覆盖，另外2例患者仍有1毫米的退缩。游离龈瓣重建了因退缩而丧失的角化组织。此外，它还使在首次手术时向冠方移位的膜龈联合得以重新对齐，从而防止前庭变浅。
