Abstract

Autogenous bone is the gold standard for bone regeneration, despite limitations such donor site morbidity and a lack of supply. This study reports a case of a 72-year-old male requiring implants in the left posterior mandible with severe bone deficiency due to prior peri-implantitis. For primary bone augmentation of such mandibular area, redundant alveolar bone was harvested in the block-form from the right maxillary area along with simultaneous implant placement in that area. The harvested block was fixed in a press-fit manner. Subsequently, the remaining defect was grafted with a synthetic bone substitute material. The grafted area was covered with a collagen membrane, followed by primary flap closure. Six months later, implant placement was performed, and the bone block was well integrated to the recipient site without mobility or fibrotic union. One year after the final prosthesis delivery, stable marginal bone level and favorable bone block integration were noted. Within the limitation of this case report, the redundant alveolar ridge can be considered as an alternative donor site for primary bone augmentation.
