Hemi-mandibulectomy causes the remaining segment of the mandible to deviate towards the resected side, this is due to the loss of soft and hard tissues on the resected side. Immediate surgical reconstruction will improve the prognosis of the rehabilitation procedures. This case report presents a patient with hemimandibulectomy defect on the left side was discussed. The patient was able to bring the mandible in proper occlusal relationship with the maxilla but was not able to maintain it for masticatory purposes. Therefore he was rehabilitated by a mandibular guide flange. Rehabilitation of the defect by mandibular guide flange will help in maintaining a proper occlusal relationship of the mandible for improved vertical stroke and chewing efficacy.

Maxillofacial defects not only create esthetic and functional problems for the patient but also have psychological and social impact on the patient. The present clinical report describes the management of a patient who had undergone partial maxillectomy, hemimandibulectomy, and partial resection of the lip on the left side. Rehabilitation of this patient was done using silicone lip prosthesis and maxillary obturator. These prostheses improve the esthetics, function, and provide confidence to the patient, hence improving his social life. The lip prosthesis was retained by two magnets that were attached to the denture cum obturator to provide good retention and stability to the lip prosthesis.
