Abstract
The biomechanical behavior of fixed prosthodontic restorations under occlusal loading is critical for long-term success, structural integrity, and patient comfort. This study investigates occlusal load distribution patterns in various fixed prosthetic designs, including single crowns, multi-unit bridges, and implant-supported prostheses, using finite element analysis, strain gauge measurements, and clinical evaluation. Emphasis is placed on the effects of restoration material, marginal design, connector dimensions, cantilever length, and occlusal scheme on stress distribution within the prosthesis and supporting structures. Findings indicate that optimal load distribution reduces the risk of mechanical complications, including fracture, debonding, and connector failure, while maintaining periodontal stability and minimizing bone resorption. Both clinical and computational results underscore the necessity of customized occlusal design and precise prosthesis fabrication to achieve favorable biomechanical performance. The study also highlights the importance of integrating digital planning and material selection to enhance the longevity and predictability of fixed restorations. Evidence-based strategies for occlusal load management are critical to achieving functional efficiency, patient satisfaction, and preservation of supporting tissues.
