摘要
对暴露的牙根表面的治疗可用于牙龈萎缩的美学改善。手术技术取决于退退的类型、退退后顶端或侧面角质化牙龈的质量和数量。本研究的目的是评估获得牙根覆盖所需的角质化牙龈的最小数量。采用冠状复位皮瓣治疗10例上颌尖凹陷。从牙根的顶端到暴露的牙根表面有不到3毫米的角化龈。所有患者均接受口腔卫生指导、菌斑控制、洗牙和牙根刨平。在手术时和术后3个月测量牙龈退缩、角化牙龈宽度和附着丧失。治疗前平均退行5.20 mm (+/- SE = 0.36), T0时角化牙龈高1.70 mm(+/- 0.16)。术后3个月,牙根覆盖平均增加3.43 mm(+/- 0.29)。术后第0个月和第3个月,衰退测量显示统计学差异,证实了该技术的有效性。角化龈初始高度与覆盖结果无相关性(r = 0.05),说明角化龈初始宽度不影响覆盖结果。
[Treatment of gingival recession with a coronally repositioned flap].
The treatment of an exposed root surface may be indicated for an aesthetic improvement of a gingival recession. The surgical technic depends on the type of the recession, the quality and the quantity of the keratinized gingiva apically or laterally from the recession. The purpose of this study is to evaluate the minimal quantity of keratinized gingiva necessary to obtain a root coverage. 10 recessions on maxillary cuspids were treated with coronally repositioned flap. Less than 3 mm of keratinized gingiva was present apically to the exposed root surface. All patients received oral hygiene instructions, plaque control and scaling and root planing. Gingival recession, width of keratinized gingiva and loss of attachment were measured at the time of surgery and three months postoperatively. The mean recession was 5.20 mm (+/- SE = 0.36) prior to treatment and the keratinized gingiva was 1.70 mm (+/- 0.16) high at T0. The mean gain of root coverage was 3.43 mm (+/- 0.29) at three months post-operatively. At T0 and 3 months post-operatively, the measures of recessions showed a statistically difference confirming the validity of the technic. The absence of correlation between initial height of keratinized gingiva and the coverage result (r = 0.05) indicates that initial width of keratinized gingiva does not affect the coverage results.
