Several approaches for horizontal ridge augmentation have been proposed, including guided bone regeneration (GBR), ridge split, and block grafts. Minimally invasive techniques for horizontal GBR have been introduced to reestablish an adequate bone volume, minimizing tissue trauma and patient morbidity. The present article describes a tunnel technique with a subperiosteal bag for horizontal GBR. A collagen membrane is partially perforated, folded, and sutured to form a bag that is filled with xenogeneic bone graft. The filled bag is inserted into a subperiosteal tunnel such that the perforated side faces the alveolar ridge and the nonperforated side faces the tunnel flap. The main advantage of this approach is the preservation of the periosteum and the enhanced blood supply to the flap, which may contribute to increased favorable wound healing and a reduced risk of flap dehiscence and membrane exposure. This novel tunnel approach for horizontal GBR using a customized bag made from a collagen membrane, specifically adapted and filled with deproteinized bovine bone, resulted in a significant ridge volume gain that allowed implant placement.
已经提出了几种水平牙槽嵴增高的方法，包括引导骨再生（GBR）、牙槽嵴劈开和块状移植。已经引入了用于水平GBR的微创技术来重建足够的骨量，将组织创伤和患者发病率降至最低。本文描述了一种用于水平GBR的带骨膜下袋的隧道技术。将胶原膜部分穿孔、折叠并缝合以形成一个袋，该袋填充异种骨移植材料。将填充好的袋子插入骨膜下隧道，使穿孔面朝向牙槽嵴，未穿孔面朝向隧道瓣。这种方法的主要优点是保留了骨膜并增强了瓣的血液供应，这可能有助于促进伤口愈合，降低瓣裂开和膜暴露的风险。这种使用由胶原膜制成的定制袋、专门适配并填充脱蛋白牛骨的用于水平GBR的新型隧道方法，导致牙槽嵴体积显著增加，从而允许植入种植体。
