[Clinical study of the two-stage hollow prosthesis on restoring unilateral maxillary defect with restricting mouth opening: a case report].

A case of a patient with a unilateral maxillary defect and restricted mouth opening was presented. The two-stage hollow maxillofacial prosthesis can be used to restore the above defect, thus promoting mastication, speaking, swallowing, and sucking, as well as improving the patient's appearance. Satisfactory results were achieved.
