Abstract

Rehabilitation of maxillectomy patients is challenging. The maxillary defects need to functional restoration because of mastication, speech, swallowing problems. The goal of making obturator is to restore maxillary defects and give patients comfortable, esthetic prosthesis. This case report presents acquired masticatory and esthetic results and improved retention resulting from the pharyngeal obturator prosthesis using implant.
