A case of fabrication obturator prosthesis for bilateral maxillary defects using magnetic attachments

Abstract

Patient: A 71-year-old male who underwent bilateral maxillectomy and mandibulectomy due to florid cement-osseous dysplasia was referred to our maxillofacial prosthetic clinic. Palatal side of tissue undercuts in the defect were planned to be engaged for gaining stability of the prosthesis. The magnetic attachments were used on the right side in which a hollow shape obturator was divided into two segments in order to engage the undercut in function and to remove from the mouth independently. The left side obturator was also fabricated into a hollow shape but united to the palatal base of the prosthesis. Assessments for masticatory function after installation of the prosthesis revealed favorable results and the patient was satisfied. Therefore, this dento-maxillary prosthesis with bilateral obturators was successful even though relatively complicated laboratory steps were required.
