Abstract: This study presents an advanced finite element analysis (FEA) of a polylactic acid (PLA)-based dental implant reinforced with bio mineral additives, aiming to optimize its structural integrity, vibrational response, and biomechanical performance. The implant undergoes static structural, modal, and harmonic response analyses to evaluate stress distribution, deformation characteristics, and resonance susceptibility under physiological loading conditions. The results indicate minimal deformation, well-distributed stress concentrations, and a stable vibrational profile, highlighting the implant’s suitability for long-term dental applications. By integrating sustainable biomaterials with computational modeling, this research contributes to the development of next-generation dental implants that ensure mechanical reliability and environmental responsibility.
