A Radiohistographic Analysis of Growth Factor-Mediated Sinus Augmentation in Atrophic Maxillae: A 30-Month Follow-up Study.

A total of 20 atrophic maxillary sinuses were augmented with recombinant human platelet-derived growth factor BB (rhPDGF-BB), alloplast, and bovine xenograft using a direct approach. CBCT imaging was performed at baseline, immediately postoperatively, and at 6 and 30 months postoperatively. A histologic evaluation revealed the bone bridging and bone regenerative efficacy of the graft material.
