چکیده مقاله :
In recent years, dental materials and implantology advancements have significantly improved the field. Precisely, focus has been placed on optimizing implant design, surface characteristics, and the implant-abutment connection. These enhancements aim to achieve better biocompatibility, improved biomechanics, increased bone-implant contact surface area, and enhanced immunological response. This study aimed to investigate the influence of crown dimensions on stress distribution in the abutment screw during loading, utilizing finite element analysis (FEA). A comparative analysis of different dental implants from the same manufacturer was conducted to evaluate their biomechanical properties. The Von Mises analysis provided insights into the biomechanical behavior of these implants. The results indicate that an increase in both horizontal and vertical cantilever lengths can potentially elevate the risk of screw loosening and fatigue fracture. This can be attributed to the heightened stress values observed in the screw or other components, such as the abutment and fixture, respectively. These findings emphasize the importance of considering crown dimensions and their impact on stress distribution during implant design and placement to ensure optimal clinical outcomes and long-term stability.
