Prosthodontic Rehabilitation of a Hemimandibulectomy Patient with Twin Occlusion Complete Denture

Hemimandibulectomy often results in significant functional and esthetic impairment due to loss of mandibular continuity, deviation of the residual segment, and compromised occlusal contacts. Prosthetic rehabilitation in completely edentulous patients presents a considerable challenge owing to the absence of proprioceptive feedback and altered mandibular dynamics. This case report describes the prosthodontic management of a 69-year-old completely edentulous female patient with a history of right-sided hemimandibulectomy. The patient was rehabilitated using a conventional mandibular complete denture and a maxillary complete denture incorporating twin occlusion on the non-resected side. This arrangement aided in guiding mandibular closure, restoring function, and improving facial esthetics. The twin occlusion setup in the maxillary prosthesis proved to be a functionally effective and economical approach for managing mandibular deviation in hemimandibulectomy patients. With appropriate training and neuromuscular adaptation, this technique significantly improved masticatory efficiency and overall quality of life.
