Ball and Socket Versus Locator Attachment Retained Implant Overdentures

Comparison of Muscle Activity and Patients Satisfaction on Implants Supported Overdenture Using Ball and Socket Versus Locator Attachment

Will the use of locator attachment influence the muscle efficacy when compared to ball and socket attachment in mandibular implant overdenture? '

In this study we will use a two different types of attachments in implants overdenture in mandibular completely edentulous patients to increase the retention and stability of the denture and this can be recognized by record the masticatory function of the muscles of the mandibular jaw.
