Abstract

Patients with maxillectomy defects predisposed to not only difficulty in deglutition, mastication, speech but also psychological depression from impaired facial esthetics that affect life quality. Obturator prostheses play a important role in restoring the lost form, function and the quality of life for patients with maxillectomy defects. This clinical report presents the simplified approach to predict the degree of adequate facial support by Artificial palate which reflected from a maxillary interim obturator during the stabilization period after maxillectomy.
