摘要

本研究旨在介绍一种牙周整形手术方法,用于治疗牙龈凹陷(GRs)和矫正下颌切牙粘龈条件和畸形。对下颌切牙(n = 24颗牙齿)中孤立的深层龈沟(≥ 3毫米)进行了治疗:66.6%的部位为 2 型或 3 型退缩,58.3%的牙齿位置不正。衰退采用游离粘液龈移植物(FMG)进行治疗,这些粘液龈移植物取自被动萌出改变或牙周支持健康的供体牙齿的颊侧,粘结釉交界处与颊侧牙槽嵴之间的距离小于 3 毫米。9 个月后对临床参数(GR、临床附着水平、近侧乳头尖位置、角化组织、前庭深度)和牙根覆盖美学评分进行评估。FMG 能明显降低 GR 值(P < .001),增加角质化组织(P < .001),但前庭深度没有降低(P > .05)。平均牙根覆盖率为 94.37% ± 10.60%,平均残余 GR 为 0.08 ± 0.65 mm,平均牙根覆盖美学评分为 8.9 ± 1.24。退缩类型 2/3 显示出明显的近端间临床附着增量(P < .05)。在乳头缺失的部位,近端间乳头明显增强(P < .001)。供体部位未发现临床附着丧失(P = .346)。这些结果表明,FMG 是一种很有前途的根面覆盖方法,适用于 1、2 和 3 型牙周退缩,可以矫正粘龈条件和畸形,重建近端乳头间。

A Surgical Approach to Root Coverage and Correction of Mucogingival Conditions and Deformities in Mandibular Incisors with Isolated Gingival Recession: Free Mucogingival Graft. A Pilot Prospective Cohort Study.

The aim of this study was to present a periodontal plastic surgery approach to treat gingival recessions (GRs) and correct mandibular incisor mucogingival conditions and deformities. Isolated deep GRs (≥ 3 mm) in the mandibular incisors (n = 24 teeth) were treated: 66.6% of sites were recession types 2 or 3, and 58.3% of teeth were malpositioned. Recessions were treated using free mucogingival grafts (FMGs) harvested from the buccal aspect of donor teeth with altered passive eruption or healthy periodontal support, with < 3 mm between the cementoenamel junction and the buccal alveolar crest. Clinical parameters (GR, clinical attachment level, interproximal papilla tip location, keratinized tissue, vestibule depth) and root coverage esthetic score were evaluated at 9 months. FMG significantly reduced GR (P < .001) and increased keratinized tissue (P < .001) without loss of vestibule depth (P > .05). Mean root coverage was 94.37% ± 10.60%, mean residual GR was 0.08 ± 0.65 mm, and the mean root coverage esthetic score was 8.9 ± 1.24. Recession types 2/3 showed significant interproximal clinical attachment gain (P < .05). The interproximal papilla was significantly augmented at sites with papilla loss (P < .001). No clinical attachment loss (P = .346) was detected at donor sites. These results suggest that FMG is a promising root coverage approach for recession types 1, 2, and 3, correcting mucogingival conditions and deformities and reconstructing the interproximal papilla.

期刊介绍: The International Journal of Periodontics & Restorative Dentistry will publish manuscripts concerned with all aspects of clinical periodontology, restorative dentistry, and implantology. This includes pertinent research as well as clinical methodology (their interdependence and relationship should be addressed where applicable); proceedings of relevant symposia or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published or submitted for publication elsewhere.
