Maxillofacial defects may be congenital or acquired and may be caused by surgical interventions for neoplasms. Because of the localisations of these defects, aesthetic problems may occur so it becomes impossible for the patients to continue their daily lives. Losing a part of the face or having a congenital defect may play a negative effect on the social life and psychology of the patient. It also affects the function adversely. Maxillofacial prostheses aim is to maintain the health of the hard and soft tissues and to improve the aesthetics of patients.
