Maxillary Prosthetic Management after Maxillary Antrostomy

—A Case Report—

Abstract

After maxillary antrostomy in a 72-year-old male, a defect in the maxillae remained without any prosthetic treatment for two years. A tampon prosthesis was very useful for the patient temporarily. A temporary obturator prosthesis was fabricated to restore function. After removing the fixed prosthesis in the right（defective bone side） upper molar region and extracting abutment teeth, a dento-maxillary prosthesis was fabricated. Rhinorrhea of saliva disturbed the patient while eating, because the prosthesis covered the parotid duct orifice which had moved upward due to the operation.
To solve this problem, we fabricated a definitive dento-maxillary prosthesis with a funnel-shaped obturator and a channel on the buccal surface of the prosthesis. The patient was satisfied with this dento-maxillary prosthesis functionally.
