This study investigates the effect of a zirconia reinforcement bar on the strength of a three-unit ceramic dental bridge. The use of ceramic bridges in dentistry is considered an optimal solution, offering a chewing experience close to natural teeth and good aesthetic outcomes. Therefore, the study simulates the mechanical behavior of a ceramic bridge with an integrated internal reinforcement bar using the finite element method (FEM) through ANSYS software, aiming to identify the locations of maximum stress concentration that may lead to fracture under chewing forces. The results presented in this paper include the identification of areas most susceptible to damage and comparing load-bearing capacity between a model without reinforcement and models with T cross-section and I cross-section reinforcement bars. Based on the simulation results, the study evaluates the stress-reduction effectiveness of different reinforcement designs and proposes shape optimizations to enhance the durability of ceramic bridges.
