Prosthetic rehabilitation of the atrophic maxilla is complex due to bone resorption and sinus pneumatization. This study evaluated stress distribution in All-on-6 implant-supported prostheses using Co-Cr and PEEK frameworks. 3D-printed skull-based models received implants in the incisor, premolar, and pterygoid regions. Strain gauges were attached to prostheses fabricated with Co-Cr and PEEK. Results showed lower stress in the pterygoid region. Co-Cr exhibited overall lower stress, while PEEK effectively reduced strain on tilted premolar implants by dissipating forces to the terminal pterygoid implant.
