This case report describes the clinical and laboratory procedures used in the rehabilitation of a patient treated for oral cancer with surgery and radiation therapy. During surgery, a large portion of the mandible was removed and reconstructed with a bone graft. Following therapy, the patient was left with poor esthetics and difficulties with mastication and speech. The goal of prosthodontic treatment was to improve esthetics and restore function. This was successfully achieved through the placement of dental implants and the construction of an implant retained overdenture. A bar was employed to split the implants together and an O-ring system was chosen for retention. The decision to use this type of prosthesis and attachment selection was based on the patient's dental history, esthetic demands, and the need for stress distribution.
