Mandibular deviation is multifactorial defect and its severity is based on the extent of osseous and soft tissue involvement, degree of tongue impaired, the loss of sensory and motor innervations, the type of wound closure, the presence of remaining natural teeth and finally the first initiation of prosthetic treatment. We describe a case of prosthetic management of a maxillary partially edentulous patient with hemimandibulectomy who reported after 4 years of postsurgical cancer therapy. A simple maxillary guided hollow inclined plane with twin occlusion acrylic prosthesis was fabricated as a functional training device to correct mandibular deviation, restore maxillomandibular relation and occlusal approximation. The patient was able to functionally achieve good maxillomandibular occlusal approximation with guidance therapy combined with physiotherapy in 2 weeks. A 6 months follow-up revealed patient satisfactory appreciation by understanding the limitations of overall prosthetic rehabilitation.
