22 Patients having lower completely edentulous mandible aged 55-60 years were selected from the outpatient dental clinic of the Medical Excellence Centre of the National Research (NRC) Cairo, Egypt. Six dental implants were inserted in the mandible of each patient. The patients were randomly categorized into two groups according to the final restoration.
Group I: received a complete removable mandibular implant supported overdenture. While Group II: received implant supported fixed bridge. Occlusal equilibrations, Muscle activities, and oral health-related quality of life (OHRQoL) were assessed by at the time of prosthesis insertion, after one and three month.
