The surgical and prosthetic rehabilitation of the patient with maxillary defects has as an objective to close the defect after the surgery through a prosthesis (surgical obturator) and to separate the oral cavity of the nasal cavity during its postoperative recovery, favoring thus to that the psychological and physical impact of the patient be smaller and can be incorporated to its social milieu. The obturator design will be successful when this it functionally recovers the patient, in where the surplus of the anatomical structures is used to maximize the support, the stability and the retention of the obturator. The prosthesis rehabilitation can be underprivileged when the defect is very ample (bilateral maxillectomy) because the support, the stability and retention of the prosthesis is diminished on the defect; giving rise to the flowed air flight and through the nasal cavity reason why its suitable function is committed. The surgical procedures help to preserve and to improve or to make worse the areas of support of the maxillectomy for the prosthesis rehabilitation. In this work two clinical cases are presented of patients with maxillectomies for discollapse the facial medium third, to which was placed them a surgical obturator with screen vestibular, to avoid the retraction of the weavings of the medium third of the face and to maximize the support, the stability and retention of the surgical obturator and with it to improve the functionality, esthetics and quality of life of the patients.
