Free gingival grafts were placed in the lower anterior vestibular region of 30 patients each of whom had a gingival recession. According to the width of the recession and to the surgical procedure, the patients were divided into four groups. Group 1 showed a "narrow" (less than 3 mm) type of recession, while Group 2 had a "wide" type. In both of these groups the graft was placed over the denuded root. In Group 3 (narrow recession) and Group 4 (wide), a collar of vestibular gingiva was left in place on the lower margin of the denuded root at the moment of grafting. Measurements and photographs taken before and 1 month after surgery, 6 months and 2 years postoperatively, showed varying degrees of root covering by the phenomenon of creeping attachment. An optimal recovery of the gingival profile was obtained in the three patients of Group 1. In the other categories of patients the creeping of the attachment apparatus was relatively small (between 0 and 33%) within the 2 years of observation. The factors which seem to have a definite influence upon the phenomenon of creeping attachment are the following: width of the recession, position of the graft, bone resorption, position of the tooth and hygiene of the patient.
对30例存在牙龈退缩的患者，在其下前牙前庭区植入游离龈瓣。根据牙龈退缩的宽度和手术操作，将患者分为四组。第1组表现为“窄型”（小于3mm）退缩，第2组为“宽型”。这两组均将龈瓣置于暴露的牙根上。第3组（窄型退缩）和第4组（宽型）在植入龈瓣时，在暴露牙根的下缘保留一圈前庭龈。术前、术后1个月、术后6个月及2年进行测量和拍照，结果显示通过上皮附着迁移现象，牙根覆盖程度不同。第1组的3例患者牙龈外形得到了最佳恢复。在其他类别患者中，在2年观察期内附着装置的迁移相对较小（0%至33%）。似乎对上皮附着迁移现象有明确影响的因素如下：退缩宽度、龈瓣位置、骨吸收、牙齿位置及患者口腔卫生状况。
