There is a paucity of data on the coverage of multiple recessions. The aim of this study was to compare clinical results of connective tissue graft (CTG) combined with tunnel surgical techniques in the treatment of multiple adjacent gingival recessions.
The treatment outcome of 28 recessions of Miller Class I and 20 recessions of Miller Class II in 18 patients was compared. Clinical evaluation, taken before the surgery as well as 6 and 12 months afterwards, included recession height, recession width, keratinized tissue width, and probing depth.
No differences of recession coverage comparing recession class I and recession class II were found (mean coverage 99.1% and 98.9%, respectively). Twelve months after surgery, 79.2% of recession class I and 72.2% of recession class II were entirely covered.
Surgical treatment of multiple recessions using CTG in combination with the tunnel technique resulted in significant root coverage of both class I and class II recessions, and increased keratinized gingival width.
关于多次牙龈退缩覆盖情况的数据较少。本研究的目的是比较结缔组织移植(CTG)联合隧道手术技术治疗多个相邻牙龈退缩的临床效果。
比较了18例患者中28处米勒I类退缩和20处米勒II类退缩的治疗结果。术前以及术后6个月和12个月进行的临床评估包括退缩高度、退缩宽度、角化组织宽度和探诊深度。
未发现I类退缩和II类退缩在退缩覆盖方面存在差异(平均覆盖率分别为99.1%和98.9%)。术后12个月,79.2%的I类退缩和72.2%的II类退缩完全被覆盖。
使用CTG联合隧道技术对多次牙龈退缩进行手术治疗,可使I类和II类退缩均获得显著的牙根覆盖,并增加角化牙龈宽度。
