Background: In sinus augmentation procedure, graft resorption remains a major dilemma of various graft materials. Objective: To estimate the graft volume changes following lateral sinus augmentation utilizing cone beam computed tomography. Methods: A total of 34 lateral sinus augmentation operations were performed and 50 dental implants were concomitantly inserted. The sinus augmentation cases were distributed randomly into 3 groups according to graft material: Group A comprised utilizing deproteinized bovine bone alone, group B using deproteinized bovine bone mixed with leukocyte and platelet-rich fibrin, and group C employing deproteinized bovine bone mixed with advanced platelet-rich fibrin. Cone-beam computed tomography was obtained 2 weeks (baseline record) and 24 weeks postoperatively for the measurement of the graft volume changes.
