Prosthodontic Management of an Irradiated Edentulous Hemi-Mandibulectomy Patient by Providing A Twin Occlusion and Salivary Reservoir – A Clinical Report.

Abstract

The prosthodontic rehabilitation of edentulous patients with acquired mandibular defects is one of the most challenging procedures confronting the prosthodontist. Tumors in and around the mandible usually require surgical removal and extensive resection of the bone. Loss of continuity of the mandible destroys the balance of the lower face leading to altered mandibular movements, decreased masticatory function and deviation of the residual segment toward the surgical site and loss of occlusion on the unresected side. The abnormal profile and position of the mandible may prevent ideal placement of the denture teeth.

Since many patients would have received radiation therapy either prior to or after surgery, xerostomia is one of the major complications in these patients causing chronic oral discomfort and functional problems. Together these conditions can impair the physiological and psychological well-being of the patient.

This clinical report describes the prosthodontic rehabilitation of an irradiated edentulous hemi-mandibulectomy patient, who had a history of carcinoma in the left side of the mandible, using two rows of non-anatomic teeth on the unresected side in monoplane occlusion, providing a broader occlusal table and improved masticatory efficiency, along with a salivary reservoir incorporated into the maxillary denture.
