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.

혀는 구강 내에서 가장 흔하게 종양이 발생하는 부위이며, 특히 측면에서 호발한다. 설암으로 인해 혀의 절제를 시행한 환자의 경우 발음, 저작, 연하 그리고 구강 위생을 위해 적절한 움직임 등의 기능에 장애를 갖게 되므로 적절한 혀의 기능을 회복하기 위해 구개 증대 보철물을 이용할 수 있다. 본 증례는 설암으로 인해 혀의 절제를 시행한 환자에서 치조설열구 및 치조제 소실 등의 불리한 조건을 임플란트를 이용한 피개의치를 이용하여 개선하였다. 또한 금속 하부구조와 지지 및 유지부를 갖는 형태의 구개 증대 보철물을 제작하여 구개 높이를 낮추어 줌으로써 제한된 혀의 운동으로도 적절한 혀구개 접촉을 얻을 수 있었다. 최종보철물 장착 후 안정적인 저작기능을 회복하였고 연하 및 발음의 문제가 개선되어 이를 보고하고자 한다.
