Abstract

Hemi maxillectomy is often secondary to malignancies and results in significant anatomical and functional deficits that profoundly impact a patient’s quality of life. Prosthetic management, specifically the use of a definitive obturator, plays a crucial role in restoring oral and nasal functionality, speech, mastication, and facial aesthetics in these patients. Patients with Armany Class 1 defects, characterized by unilateral maxillary resection, face unique challenges that necessitate specialized prosthetic intervention. This article describes prosthetic rehabilitation of hemi maxillectomy patient, focusing on the design, fabrication, and fitting of cast partial denture with closed hollow bulb obturator. Precision attachment adds the benefit of improved esthetics and better distribution of stresses to the remaining natural teeth.
