Abstract
|
|
|
|
The tongue, especially its lateral part, is the most common site of oral tumors. Patients who undergo glossectomy for the treatment of tongue cancer may experience difficulty in proper functioning for pronunciation, chewing, swallowing, and oral hygiene maintenance; therefore, a palatal augmentation prosthesis can be used to restore function of the tongue. In this case, an implant overdenture was used in a patient who had residual ridge resorption and obliteration of alveololingual sulcus after undergoing glossectomy for tongue cancer treatment. In addition, a palatal augmentation prosthesis with a metal framework, support, and retention part was fabricated. The palatal vault was reduced, so that even with limited tongue movement, adequate tongue-palate contact could be achieved. After placement of the definitive prostheses, the patient showed improvement in the functions of chewing, swallowing, and pronunciation.
