作者介绍了一种采用结缔组织和非全厚双蒂瓣使暴露牙根获得覆盖的方法。选择18～41岁20名患者(男19女1)的30处病损进行手术。术前记录牙周袋深度,牙龈退缩的高度和宽度,龈组织的角化程度,龈上菌斑数,探诊出血区等项指标,并进行洁治、根面平整等基础治疗。手术在局麻下进行,首先在受累牙的釉牙骨质界水平分别向近远中各作一水平切口,其末端距邻牙龈缘不少于0.5mm,于近远中水平切口末端向牙槽粘膜各作一垂直切口并使切口连成角形。翻起非全厚双蒂 The authors describe a method of covering the exposed root using connective tissue and non-full-thickness, dual-pedicle flap. Thirty lesions between 20 and 18 years old (19 male and 1 female) were selected for surgery. Preoperative records of the depth of the periodontal pocket, the height and width of the gingival recession, the degree of gingival tissue, the number of supragingival plaque, bleeding and other indicators of exploration, and clean treatment, root formation and other basic treatment. Surgery under local anesthesia, first in the affected tooth glaze cementum level respectively to the near and far for a horizontal incision, its end away from the gingival margin of not less than 0.5mm, in the near and far horizontal incision to the teeth Trench mucosa for a vertical incision and the incision even into an angle.
