ABSTRACT
Implant reconstruction of the severely resorbed edentulous maxilla frequently requires autogenous block bone graft reconstruction. Advanced maxillary bone graft reconstruction requires autogenous corticocancellous block onlay, inlay or interpositional bone grafting. Each type has indications and can be either one or two staged. Bone graft reconstruction of small- to medium-sized congenital alveolar–palatal defects requires cortico-cancellous block bone grafts to completely restore the nasal floor, palate and piriform rim to achieve the most ideal nasal and dental implant aesthetic result. The reconstructive surgeon, prosthodontist and patient need to decide whether to replace lost anatomy or obturate lost anatomy in early planning of corrective surgery for large postsurgical or post-traumatic maxillary defects. Endosseous implant reconstruction of advanced bone resorption of the edentulous mandible can be achieved with a minimum of 5 mm of bone height and 6 mm of bone width. Bone regeneration of severely resorbed mandibular body occurs following functional loading of osseointegrated endosseous dental implants placed in the mandibular symphysis region.
