Abstract
In the case of congenital malformation, acquired trauma, or maxillectomy by neoplasm, the defect in maxilla is combined with nasal cavity, maxillary sinus and oral cavity. This results in abnormal function in pronunciation, mastication, and swallowing. In this situation, the purposes of prosthodontics are also applied. The purposes of obturator for acquired maxillary deficiency patients are restoring pronunciation, mastication, and swallowing, and make patients comfortable and esthetic satisfaction. Reducing weight of the obturator makes edentulous ridge heathy and functional. It also improves patients' comfort. Hollow obturator also reduces unnecessary stress because improves physiologic function, as it weights less than 6.55-33.06% compare to usual one. This case presents the double-processing method for maxillary obturator in the patient treated hemi-maxillectomy due to malignancy neoplasm. We report this case because the patient acquired functional and esthetic satisfaction from double-processing obturator.
