The maxillary tumors include various histological entities which are the subject of a very particular treatment. Clinical, radiological and anatomopathological criteria are used to determine the diagnosis. In spite of the evolution of reconstructive surgical techniques and the development of microsurgery, the conventional obturator prosthesis is still in use nowadays. In this context, it must restore the main functions of chewing, phonation and deglutition and give the patient a satisfactory aesthetic appearance.

The direct effects of cancer and the therapeutic sequelae have a profound impact on the patients' quality of life. The resultant loss of maxillary substance is accompanied by serious functional, aesthetic, psychological and social problems. The maxillofacial obturating prosthesis remains as a therapeutic tool that improves aesthetics and restores the various functions of chewing, swallowing and phonation. A tight collaboration between the maxillo-facial surgeon and the dentist is essential to obtain an optimal prosthesis both functionally and aesthetically, thus allowing a socio-professional reintegration of the patient.
