Despite advances in preventive dentistry in Brazil, the number of edentulous individuals is still great. Many patients present difficulty when using conventional dentures, especially towards the mandibular one. A treatment option for these situations is the installation of implant-retained prostheses. Although this treatment is well established in the literature, there are no studies comparing what happens to muscles and quality of life of patients during the treatment. We selected 12 completely edentulous patients, according to pre-established inclusion and exclusion criteria, to rehabilitate with mandibular overdentures retained by two dental implants and a complete denture as antagonists. We evaluated the efficacy of the treatment and its evolution in five distinct steps, initially with the old complete dentures (I) after the implants placement with the mandibular prosthesis relined (II) after the placement on of the healing abutments (III), after the installation and adaptation of new prostheses (IV) and after three months of its use (V). At each stage, we evaluated patients through the temporal and masseter electromyography (EMG), bite force and the questionnaire OHIP Edent to assess the quality of life of these patients. The results for EMG found a decrease in muscle activity during the mastication of raisins, rest and lateral movements, while the bite force and the quality of life of patients gradually improved during the study (p ˂ 0.05). Proving that this rehabilitation should become standard for edentulous individuals and that the benefits of treatment are observed even before its completion.
