Abstrakt: Maxillectomy defects can result in oroantral communication that causes difficulty in mastication and deglutition, impaired speech, and facial disfigurement. The prosthodontist plays an important role in the rehabilitation of such defects with obturators. This paper describes a clinical report of fabricating a definitive obturator with a cast metal framework using a single flask and one-time processing method for an acquired maxillary defect. A tripodal design was selected for this case. Rest was placed on the premolars and molars of both quadrants of the maxilla. Complete palate as the major connector was designed to ensure maximum distribution of the functional load to the tissue. Indirect retainer was planned on the right first premolar. Direct retention was provided by the I-bar clasp placed on the left first premolar, circumferential clasp on the right first premolar, and embrasure clasp between the right first and second molars. Thus, this definitive prosthesis rehabilitated the patient by providing better masticatory efficiency, improving the clarity of speech and quality of life of the patient.
