Abstract
A restricted mouth opening in hemimaxillectomy patients can create a significant problem with insertion and removal of the obturator prosthesis. A two-piece obturator is an alternative management for such patients. The treatment of a patient with a hemimaxillectomy due to squamous cell carcinoma is presented in this clinical report. A sectional obturator prosthesis retained by magnets was fabricated to deal with trismus, fibrosis, and microstomia. The patient's esthetic and functional expectations were satisfied. The new generation of magnets with improved technology provides sufficient denture retention for clinical application. However, further follow-up may be necessary to ascertain the long-term usefulness of the magnet-retained obturator prosthesis, because of corrosion and further loss of magnetism.
