The aim of the present case report was to illustrate how to obtain an ideal alveolar ridge contour by means of peri-implant soft-tissue management combined with the prosthetic approach of the biologically oriented preparation technique (BOPT). A patient presenting a moderate vertical and horizontal bone loss in the posterior maxilla was treated with sinus floor elevation and simultaneous implant placement. During the reentry procedure, the horizontal defect was corrected with an apically repositioned flap combined with a connective tissue graft. To increase the volume of the interimplant papillae, a pedunculated flap originating from the primary flap was turned within the interimplant space. BOPT one-time abutments have been employed to maximize the space available for the papilla-like tissues. A focused and combined surgical and prosthetic procedure has permitted enhancement of both peri-implant esthetics and function without the need for further invasive and costly bone regeneration techniques.
本病例报告的目的是说明如何通过种植体周围软组织管理结合生物导向制备技术（BOPT）的修复方法来获得理想的牙槽嵴轮廓。一名上颌后部出现中度垂直和水平骨丢失的患者接受了上颌窦底提升术并同期植入种植体。在再次切开手术过程中，采用根尖向复位瓣联合结缔组织移植来纠正水平缺损。为增加种植体间乳头的体积，将源自初始瓣的带蒂瓣在种植体间间隙内翻转。采用BOPT一次性基台以最大化乳头样组织可用空间。聚焦且联合的手术和修复程序在无需进一步侵入性且昂贵的骨再生技术的情况下，实现了种植体周围美学和功能的提升。
