Prosthodontic rehabilitation of hemimandibulectomy with cast partial denture: a case report

Mandibulectomy is a procedure that is used to eradicate disease that involves the lower jaw or mandible. Surgical resection of mandible owing to benign, malignant neoplasm, and osteoradionecrosis is common. The resection can be total or segmental depending on the extend of the lesion. In the case of segmental resection or hemimandibulectomy which is removal of only one side of the mandible, loss of mandibular continuity causes deviation of remaining mandibular segment towards the resected side and rotation inferiorly due to muscle pull and scar contracture affecting mastication and esthetics. Surgical reconstruction may not be always possible. Prosthetic rehabilitation plays an important role in these patients. This case describes the prosthodontic management of hemimandibulectomy with regular cast partial denture. Guiding flange prosthesis was avoided in this case because there was no occlusal deviation. The deviation of the mandible towards the resected side was due to scar contracture only.
