A modified technique using a submarginal free mucosal graft has been developed to aid in root coverage. The gingival collar of keratinized tissue is relaxed via a horizontal or semilunar incision and coronally placed. The periosteum is retained on the osseous structures of the recipient site. A free mucosal graft from the palate is sutured submarginally, while the dentist places tension on the gingival collar in an incisal direction. This method has been found, in 8 years of study, to be a predictable way for the periodontist to cover receded gingival tissue where esthetics or root sensitivity is a factor.
一种使用边缘下游离黏膜移植的改良技术已被开发出来，以帮助实现牙根覆盖。通过水平或半月形切口使角化组织的牙龈颈松弛并向冠方移位。骨膜保留在受植区的骨结构上。将取自腭部的游离黏膜移植片缝合在边缘下，同时牙医在切向方向对牙龈颈施加张力。经过8年的研究发现，对于牙周病医生而言，在美观或牙根敏感是一个影响因素的情况下，这种方法是覆盖退缩牙龈组织的一种可预测的方式。
