Purpose: The current "gold standard" in alveolar ridge augmentation is autogenous bone grafting. Autologous cortical onlay grafts provide predictable increases in bone volume when used for alveolar ridge augmentation; however, rigid fixation of the graft to the recipient site is essential. Titanium screws are commonly used to provide rigid fixation for Way grafting but have potential drawbacks including the need for a second surgery for removal before implant placement and screw fracture during removal. The present study investigated the efficacy of resorbable fixation screws to secure autologous cortical onlay grafts to the maxilla or mandible to augment alveolar bone height and/or width before implant placement.
