Regenerating a periodontium that has been lost because of disease has been made possible by the use of demineralized freeze-dried bone allografts (DFDBA), guided tissue regeneration with e-PTFE membranes, and combination therapies involving DFDBA covered by either an e-PTFE membrane or calcium sulfate. During regenerative therapy, problems may arise because of an adverse mucogingival condition, loss of a papilla, or significant exposure of the membrane from soft-tissue recession, slough, or fenestration leading to direct exposure of the site to the oral environment. Pedicle procedures can be used to cover these regenerative sites while providing mucogingival repair.
通过使用脱矿冻干异体骨（DFDBA）、e-PTFE 膜引导组织再生以及涉及用 e-PTFE 膜或硫酸钙覆盖的 DFDBA 的联合疗法，已能够再生因疾病而丧失的牙周组织。在再生治疗期间，可能会因不良的龈黏膜状况、乳头丧失或膜因软组织退缩、脱落或开窗而显著暴露，导致该部位直接暴露于口腔环境而出现问题。带蒂手术可用于覆盖这些再生部位，同时进行龈黏膜修复。
