Abstract

This clinical report details a novel surgical modification at the time of maxillectomy to improve obturator function. A vestibuloplasty and split thickness skin graft of the zygomaticoalveolar crest created a denture-bearing surface that, when engaged, provided support and stability for the obturator prosthesis. This report outlines the surgical and prosthodontic procedures and the results achieved.
