Abstract Aim: This RCT is to evaluate the activity of masticatory muscles beside patient satisfaction of implant supported mandibular overdentures using two different types of attachments (ball and socket versus locator) in completely edentulous patients after insertion of attachments by two weeks, three months and six months. Methodology: The proposed number of the patients was 24, 12 per each The patients were divided into two groups: group A: patients receive mandibular overdenture with ball & socket attachments group B: patients receive mandibular overdenture with locator attachments Results: Implant retained mandibular overdentures with locator attachment system provide high muscle activity in comparison with implant retained mandibular overdentures with ball and socket attachment system. Conclusions: The muscle activity of masseter is higher than temporalis muscle and the activity of masseter and temporalis muscles increase with time. Patient satisfaction in the present study with locator attachments system was superior to ball and socket.
