Treatments with prostheses on implants must be very well planned and executed, in order to have adequate maintenance and longevity. Thus, the present work demonstrates, through a clinical case report, the making of an overdenture prosthesis on two implants previously installed in the mandible and a conventional complete denture in the upper arch, considering the biopsychosocial principles of the patient. Male patient, 74-year-old, who underwent radiotherapy treatment, attended the Oral Oncology Center – FOA UNESP, for oral rehabilitation, after treatment of squamous cell carcinoma, complaining mainly of masticatory inefficiency due to edentulism. Intraoral clinical examination revealed a healthy gingiva in its entirety. In the maxillary ridge, an adequate bone height of the ridge was observed, however, with a failure in the posterior region on the left side due to surgery performed in the previous oncological treatment. In the lower arch, it was possible to observe bone resorption of the ridges and two implants (S.I.N. Implant System) already installed, parallel and stabilized (monitored by a device named Osstell) in the anterior region of the mandible. The treatment plan was defined by the elaboration of two prostheses, making an upper conventional complete denture and a lower overdenture-type prosthesis, taking advantage of the two implants previously installed in the radiotherapy sessions. After the installation of the prostheses, it was possible to diagnose greater masticatory comfort, improvement in aesthetics and self-esteem, managing to promote quality and longevity in the treatment according to the patient’s needs and age, restoring oral health and him.
