Finite element analysis (FEA) has become integral to advancing dental implantology, offering critical insights into the biomechanical behavior of implants and their interaction with surrounding bone. By examining stress distribution and load pathways, FEA enables the optimization of implant geometry, particularly thread shape and depth, to foster favorable bone collagen fiber orientation. These findings underscore the importance of patient-specific designs, which can now be realized through additive manufacturing to accommodate variations in bone quality. Additionally, incorporating physiological loading scenarios in FEA simulations improves the accuracy of stress predictions, helping to mitigate implant failure risks. Recent research has also highlighted the potential of coupling FEA with artificial intelligence (AI), facilitating efficient parameter optimization and multiscale modeling. While these tools have substantially contributed to understanding the bone-implant interface, future work should emphasize in vivo validation. Such collaborative efforts between engineers, clinicians, and researchers will ultimately enhance implant longevity and elevate patient outcomes.
