Abstract
The causes for defects in the maxilla can be congenital, acquired, developmental, traumatic or surgical involving the oral cavity and contiguous anatomic structures. Absence or loss of some or all of the soft palate and / or hard palate results in insufficient structure or altered function/aesthetic , disruption of articulation and airflow during speech production and also nasal reflux during deglutition. Patients after surgical resection have altered hard/soft tissue anatomy due to scaring, tissue contracture, lack of adequate bony support and tissue edema. Such patients have problem of regurgitation of water and food through nose and difficulty in speech. Rehabilitation of such patients requires the fabrication of obturator prosthesis and also sometimes repeated prosthesis adjustments to conform to the soft tissue changes. In such a situation an obturator is designed in such a fashion to take the maximum advantage of remaining hard and soft tissue /anatomical favourable sites.
Key Words- cast metal framework., Obturator, Squamous cell carcinoma.
