Objective: The aim of this study was to radiologically evaluate the bone remodeling of sinus graft performed with autogenic bone from the iliac crest or from the cranial vault. Methods: Radiographs of 24 individuals subjected to maxillary sinus lift were assessed at the following stages: preoperative (T1), immediate postoperative (T2) and late postoperative (T3). Measurements were performed on panoramic radiographs to determine the remaining alveolar bone (T1), from the alveolar ridge bone crest to the maxillary sinus floor, bone height (ridge + graft) after bone graft and implant surgery (T2) and bone height (ridge + graft) one to five years with implants in function (T3). Results: At T2, the average increase of sinus on the right side was 12.60mm (iliac crest bone graft) and 12.44 mm (cranial vault bone graft), while on the left side, it was 11.83mm (iliac crest bone graft) and 11.89mm (cranial vault bone graft). At T3, the average measurement of right maxillary sinus was 10.00mm for the iliac crest bone graft, while for cranial vault bone graft it was 8.56mm. In the left maxillary sinus, the average was 8.83 mm for the iliac crest bone graft and 7.83mm for cranial vault bone graft. It was concluded that there was no statistical difference between the values of bone height of sinus grafts with bone harvested from the iliac crest or from the cranial vault (p < 0.05) at the time of implant placement and after functional load. Conclusion: Therefore, it was concluded that there is no difference, from the point of view of maintenance of the amount of sinus lifting, between autogenous bone graft harvested from the iliac crest and from the cranial vault.
