Posterior maxillary atrophy: Surgical Treatment Modalities
The partial edentulous posterior maxilla often requires bone reconstructive surgery for implants placement. Alveolar atrophy is a pathological condition characterized by moderate or severe resorption of alveolar bone due to teeth loss. Alveolar bone resorption and the location of the maxillary sinus, make the posterior regions of the maxilla challenging to treat while using dental implants. This lecture focuses on augmentation procedures with natural tissues, and biomaterials for vertical and horizontal bone augmentation to restore edentulous ridges with implant-supported prostheses successfully. Bone-augmentation techniques proposed to increase bone volume in the posterior regions of the maxilla will be presented, including ridge preservation covered with membrane, sinus augmentation procedure, and guided bone regeneration (GBR), onlay autologous block bone grafts (AOBG) for horizontal and vertical augmentation.
