Milled Bar-Supported Implant Overdenture After Mandibular Resection: A Case Report
After surgical treatment for oral cancer, patients often are affected by disfigurements, thwarted function, and psychological and social problems. Prosthodontic rehabilitation has the aim of restoring function and esthetics. Implant-supported prosthodontic rehabilitation is useful for patients with compromised residual ridge anatomy, such as patients with oral cancer following treatment. This clinical report describes the rehabilitation of a patient after mandibular resection with a milled bar-supported implant overdenture. Overdenture achieves best hygienic maintenance, easy soft tissue follow-up, and low realization cost. This rehabilitation increased prosthesis retention and stability and improved oral conditions and the patient's quality of life.Abstract
