Rehabilitation of Hemi-Mandibulectomy Patient with Twin Occlusion Prosthesis

Abstract

The mandible is a single bone that makes the lower third of the face and forms peripheral boundaries of floor of the mouth. Surgical resection of mandible owing to benign, malignant neoplasm, osteoradionecrosis is common. Loss of mandibular continuity causes deviation and rotation inferiorly due to muscle pull and scar contracture affecting mandibular movements, mastication, speech and aesthetics. Case Report: This case report describes prosthetic rehabilitation of a patient with post hemi-mandibulectomy residual defect. Patient underwent surgical resection of mandible right side distal to canine resulted in deviation and rotation of mandible towards the defect side. Because of restricted manipulation of mandible towards non-resected side, dual occlusion prosthesis in maxillary arch was planned to improve masticatory efficiency. Conclusion: Patients with excessive scar contracture limits mandibular manipulation towards normal side to achieve occlusion. These patients are rehabilitated with dual occlusion prosthesis to restore function.
