背景：牙龈退缩在其局部或全身的形式是一种不良的条件，导致根暴露。表现出米勒IV级牙龈退缩的部位不适合用外科根面覆盖技术治疗，并且它们的牙龈退缩用当前技术非常差。本病例报告的目的是建立一种新的技术，用于严重牙龈退缩缺陷的根面覆盖（米勒IV类）通过使用带蒂颊脂垫（PBFP）提供具有良好血供的足够组织的新来源。在上第二磨牙水平，通过颊瓣基部的切口移动PBFP，结果：在牙根退缩缺损处，获得了临床上显著量的角化牙龈，覆盖了牙根退缩缺损。6周后颊脂垫上皮化完成，与健康的角质化粘膜的角化gingivalv.Conclusions的解剖部位的形成：PBFP技术是简单，易于处理。它也可以被认为是一种新的应用，对严重牙龈退缩缺陷（米勒IV类）的牙根覆盖具有有希望的结果，可以提供相当数量的角化组织用于上后磨牙的牙根覆盖。
Background: Gingival recession in its localized or generalized form is an undesirable condition resulting in root exposure. Sites exhibiting Miller Class IV gingival recession are not suitable for treatment with surgical root coverage techniques, and their prognoses are very poor with current techniques. The aim of this case report is to establish a new technique for the root coverage of severe gingival recession defects (Miller Class IV) by providing a new source of enough tissue with good blood supply using the pedicled buccal fat pad (PBFP).Methods: The PBFP was mobilized through an incision in the base of the buccal flap at the level of the upper second molar, the vascularized flap was secured to the buccal surface of the upper first molar tooth and premolar teeth and sutured with the wound margins.Results: A clinically significant amount of keratinized gingiva that covered the root recession defect was obtained. Epithelialization of the buccal fat pad was completed after 6 weeks, with formation of healthy-looking keratinized mucosa in the anatomic site of the keratinized gingiva.Conclusions: The PBFP technique is simple and easy to handle. It may also be considered a novel application with promising results for the root coverage of severe gingival recession defects (Miller Class IV) that may provide a considerable amount of keratinized tissue used for root coverage of the upper posterior molar teeth.
