Bone and soft tissue loss are common problems after lose of tooth and that can lead to excessive length of clinical crowns. In large amount of bone loss, a number of graft materials have been used in vertical and horizontal ridge augmentation to enable implantplacement in optimal positions. Autogenous block grafts from intraoral or extraoral regions have been used with positive results. Allograft blocks with cortical bone are also used for ridge augmentation. In this case report a 21-year-old male patient with maxillary and mandibular bone loss due to traffic accident was rehabilated. An allograft block was used for horizontal and vertical augmentation of the maxilla and mandibula. The observed increase in ridge width allowed subsequent implant placement after a 5 month healing period. After 4 months from placement of the implants, implant-retained fixed prosthesis was performed
