This prospective cohort study is designed to gather preliminary data on the improvement of patient satisfaction and oral function for individuals wearing distal extension partial dentures that are supported by smaller length dental implants. Thirty healthy male and female participants aged 18 to 65 will be treated at the University of Minnesota Dental School, in the Clinical Research Center. A lower partial denture will be fabricated using routine prosthodontic techniques. The participants will receive a 7 mm X 3.75 mm or a 8.5 mm X 4.1 mm tapered implant, A Locator Abutment will be used to connect the denture to the implant to improve the retention and stability of the partial denture. The chewing ability and chewing pattern will be evaluated with a jaw-tracking device and the masticatory muscle activity will be evaluated with surface Electromyography (EMG). OHRQoL, chewing function, and patient satisfaction will be measured at the 1, 2, 6, and 12-month recall appointments.
