Reconstruction of the severely atrophic maxilla with autogenous iliac bone graft and hydroxylapatite/decalcified freeze-dried bone allograft in the same patient: a preliminary report.

Procedures to augment the severely atrophic maxilla using sinus lift techniques have been increasingly used for endosseous implant placement. A case report is presented in which a patient had a severely resorbed maxilla bilaterally. A situation developed during the course of treatment which created a unique opportunity to compare an autogenous iliac graft on one side with a hydroxylapatite/freeze-dried bone allograft on the other.
