Abstract

Prosthetic rehabilitation of a severely atrophic anterior maxilla is challenging. To achieve aesthetic and functional outcomes with anterior implant-supported restorations, horizontal or vertical bone augmentation should be performed prior to implant placement. Autogenous block-bone grafting is the gold standard for onlay graft techniques; however, it is associated with problems, such as patient discomfort due to additional surgery at the intra- or extra-oral donor site. Therefore, the allogeneic block-bone graft, which is relatively less traumatic and safer, is used for convenience, and the high success rate in previous studies has proven the reliability of this technique. Herein, we report two cases in which allogeneic block-bone was successfully grafted in single and long-span defects in the maxillary anterior region, with satisfactory aesthetic and functional outcomes that were stable at regular follow-ups after surgery.
