Abstract Background Implant rehabilitation following post-traumatic dentoalveolar defects can be challenging due to irregular bone loss and insufficient ridge volume that compromise dental implant placement and prosthetic rehabilitation. Aim of the study To evaluate implant rehabilitation following reconstruction of delayed post-traumatic maxillary and mandibular dentoalveolar defects using iliac crest bone grafts in terms of implant stability (primary outcome), marginal bone loss, graft success
