This study investigates the stress distribution in premolars and bioimplants under various load conditions to enhance understanding of their mechanical behavior and inform clinical practices in dental implantology. Premolars play a crucial role in dental function, and their interaction with bioimplants during load-bearing activities is vital for ensuring the longevity and success of dental treatments. Finite element analysis (FEA) was employed to model the biomechanical behavior of premolars and bioimplants subjected to different loading scenarios, including axial, oblique, and lateral forces. The results reveal distinct patterns of stress distribution, highlighting how varying load conditions influence the mechanical response of both biological and implant structures. Notably, the study identifies critical stress points that could contribute to potential failure or complications in dental implants. These findings provide valuable insights for dental practitioners, facilitating improved implant design and treatment planning that account for the mechanical interactions between natural teeth and bioimplants. Ultimately, this research contributes to the advancement of dental implant technology and the optimization of patient outcomes in restorative dentistry.
