Bilaminar procedures represent an evolution in the treatment of marginal tissue recessions. A connective tissue graft removed from the palate and over which a pedicle flap is sutured, is used in these procedures. The advantages of these new procedures are: 1) sure predictability of graft survival to which a double-blood supply is guaranteed; 2) primary intention healing at the donor site, with minimum post-operative discomfort; 3) excellent esthetic results consisting of better color blending between graft and adjacent tissues and absence of keloid- like scars, very common after free gingival grafts.
双层手术代表了边缘组织退缩治疗方法的一种演进。在这些手术中，使用从腭部取下的结缔组织移植物，并在其上缝合带蒂瓣。这些新手术的优点包括：1）移植物存活具有可靠的可预测性，因为有双重血液供应保证；2）供区一期愈合，术后不适最小；3）美学效果极佳，移植物与相邻组织之间颜色融合更好，且没有游离龈移植后非常常见的瘢痕疙瘩样瘢痕。
