Bone grafts and titanium implants are normally employed for surgical/prosthetic treatment of the atrophic edentulous maxilla. The aspects that have an impact on bone graft recovery and implant integration aren’t adequately understood. The purpose of this dissertation ended up being to assess autogenous bone grafting and deferred placement of titanium endosteal implants for reconstruction of the atrophic maxilla, including the effects of various patient factors on bone graft healing and integration of titanium implants into grafted bone. A total of Forty six individuals with severe maxillary atrophy received onlay- (n=35) or interpositional bone grafts (n=11) and 6 mo. later received 341 titanium endosteal implants…….
