"Maxillofacial prosthodontics" is the branch of prosthodontics concerned with the restoration and / or replacement of the stomatognathic and craniofacial structures with prostheses that may or may not be removed on a regular or elective basis. Maxillary resection has a high level of morbidity, with significant psychological and functional implications for the patients. To restore function, it is essential that the surgical defect be obturated adequately to prevent escape of air, fluid and food between the oral and nasal cavities. In larger resection cases the obturator may also need to provide support for the overlying facial tissues.
