A new mucogingival surgical technique for root coverage is proposed. Two kinds of flaps were obtained from the tissue surrounding the recession: the first, a partial thickness-epithelial connective flap, was designed to cover the second flap, which was a connective double-papilla flap positioned directly on the root surface. This technique was used to treat 11 cases of gingival recession ranging from 3 to 5 mm. After a period of 12 months, the mean root coverage was 84% with an average recession reduction of 2.7 mm, and the keratinized gingiva obtained was adequate in width and in thickness. The advantages of the suggested surgical technique are: (1) a single-step procedure is used, (2) there is no need for a second donor site, and (3) the achievement of a good final esthetic result with uniformity in the color and morphology of the flap relative to the surrounding tissues.
本文提出了一种用于牙根覆盖的新型膜龈外科技术。从牙龈退缩周围的组织获取两种瓣:第一种是部分厚度的上皮结缔组织瓣,设计用于覆盖第二种瓣,即直接位于牙根表面的结缔组织双乳头瓣。该技术用于治疗11例牙龈退缩3至5毫米的病例。12个月后,平均牙根覆盖率为84%,平均退缩减少2.7毫米,获得的角化龈在宽度和厚度上均足够。所建议的外科技术的优点是:(1)采用单步手术;(2)无需第二个供区;(3)最终获得良好的美学效果,瓣与周围组织在颜色和形态上具有一致性。
