palatal augmentation prosthesis

Definition from Glossary

A removable maxillofacial prosthesis which alters the hard and/or soft palate's topographical form adjacent to the tongue. It allows reshaping of the hard palate to improve tongue/palate contact during speech and swallowing due to impaired tongue mobility as a result of surgery, trauma, or neurological/motor deficits
