Aim: Compare the prosthetic maintenance between two different framework materials for full arch mandibular fixed prostheses (zirconia over titanium bar and full arch zirconia) during a one-year follow-up. Materials and Methods: Fourteen completely edentulous participants were selected. For each patient, six implants were installed in the mandible using a surgical guide. Participants were randomly divided into two groups. Group A: Mandibular fixed implant -supported prosthesis was constructed using zirconia over titanium bar framework and Group B: Mandibular fixed implant-supported prosthesis was constructed using full arch zirconia. The prosthetic complications were recorded from the time of prosthesis insertion for one year. Results: It was found that there was no significant difference between both groups regarding the incidence of different prosthetic complications. Conclusion: Within the limitation of this study, the type of prosthesis material either full-arch zirconia or zirconia over a titanium bar has relatively similar impact on the frequency of maintenance of prosthetic components.
