For the edentulous patients who underwent mandibulectomy because of the treatment of malignant tumor, it is difficult to apply a usual denture in the cause of occlusal disorder. In this report, two edentulous cases after hemimandibulectomy reconstructed by only myocutaneous flap, who recovered from a masticatory dysfunction by implant-supported dento-maxillary prosthesis are presented. The mandible of these cases were left to be cut, therefore the residual mandible showed instability in jaw opening and closing, and implant placement areas were limited within the non-resected side. However, devised abutments and jaw movement training achieved complete stable prostheses which improved the mastication and the quality of patients’ life.
