Gingival recession is a common problem that requires periodontal surgery to restore esthetics. The vestibular incision subperiosteal tunnel access (VISTA) technique is a minimally invasive recession coverage method that has gained popularity. This case series reviews the treatment outcomes in 10 patients with a total of 28 Miller Class I or Class II recession defects in the maxillary anterior region. The defects were treated with the VISTA technique alone without any grafting material. The clinical parameters measured at baseline and at 3- and 6-month follow-up examinations were probing depth, clinical attachment level, Gingival Index, width and thickness of attached gingiva, and height of gingival recession. Statistical analysis (repeated-measures analysis of variance with a post hoc Bonferroni test) revealed that all clinical parameters except probing depth and thickness of attached gingiva showed statistically significant improvement from baseline to the follow-up examinations (P < 0.001). A mean root coverage of 78.99% was achieved. Even when performed without any grafting material, the VISTA technique is a reliable method to obtain recession coverage in the maxillary anterior region.
牙龈退缩是一个常见问题,需要进行牙周手术来恢复美观。前庭切口骨膜下隧道入路(VISTA)技术是一种微创的退缩覆盖方法,已受到广泛关注。本病例系列回顾了10例患者上颌前部共28处米勒I类或II类退缩缺损的治疗结果。这些缺损仅采用VISTA技术进行治疗,未使用任何移植材料。在基线以及3个月和6个月随访检查时测量的临床参数包括探诊深度、临床附着水平、牙龈指数、附着龈宽度和厚度以及牙龈退缩高度。统计分析(采用事后Bonferroni检验的重复测量方差分析)显示,除探诊深度和附着龈厚度外,所有临床参数从基线到随访检查均有统计学显著改善(P < 0.001)。平均牙根覆盖率达到78.99%。即使不使用任何移植材料,VISTA技术也是在上颌前部获得退缩覆盖的可靠方法。
