We present the preliminary results of the treatment of teeth with a deep, non-contained periodontal residual defect, vestibular bone dehiscence, and soft tissue recession, by combining an apical non-incised papilla surgical approach (NIPSA) to the defect and leukocyte platelet-rich fibrin (L-PRF) in the vestibular aspect. Four patients (upper left first premolar, upper left central incisor, upper right central incisor and upper right lateral incisor) have been treated. At one year of follow up, all cases showed a considerable reduction in the periodontal pocket depth, a gain in clinical attachment and no bleeding on probing, as well as an improvement in the marginal soft tissue minimizing soft tissue contraction (recession and/or loss of papilla) and improving soft tissue architecture. NIPSA plus L-PRF seem to improve clinical outcomes in deep non-contained intrabony defects associated with soft tissue recession.
我们展示了通过将根尖非切开乳头手术入路（NIPSA）应用于缺损处并在前庭侧使用富含白细胞血小板纤维蛋白（L-PRF），来治疗存在深部、非局限性牙周残余缺损、前庭骨开裂和软组织退缩的牙齿的初步结果。已对4例患者（左上第一前磨牙、左上中切牙、右上中切牙和右上侧切牙）进行了治疗。在随访一年时，所有病例的牙周袋深度均显著减小，临床附着获得增加，探诊无出血，并且边缘软组织得到改善，使软组织收缩（退缩和/或乳头丧失）最小化并改善了软组织结构。NIPSA联合L-PRF似乎能改善与软组织退缩相关的深部非局限性骨内缺损的临床疗效。
