Abstract
|
|
|
|
Congenital or traumatic loss on the oral and maxillary area or the loss of jaws due to the surgical excision of a tumor causes functional problems, such as masticatory and swallowing disorders, phonetic problems and psychological disorders in patients. In most cases, a prosthetic restoration is needed to resolve these problems and restore the damaged tissue and function. When loss occurs on the maxilla, foods and liquids leak into the nasal cavity, and a nasal sound can be heard due to air leakage into the removed area. In these cases, the palatal obturator can be used to improve the esthetic and functional aspects because it restores the removed area of the maxilla and closes the opened route between the oral cavity and maxillary sinus or nasal cavity. In this case report, a palatal obturator was applied to patients who had a hemimaxillectomy due to the occurrence of squamous cell carcinoma on the right maxillary area. Therefore, fundamental functions, such as phonetic and swallowing functions were restored, and the esthetic aspects of the facial profile were improved.
