Published on: October 17, 2016

  • 27 microscopic models with varying particle gradients (30-70μm) were analyzed.
  • Response Surface Method (RSM) and multiobjective optimization were utilized.

    • Main Results:

    • The 50-30-30μm particle gradient configuration showed a 20% increase in bone-implant contact (BIC) ratio and reduced peak Tresca shear stress (PTS).
    • Optimal gradients were identified for maximizing BIC ratio (30.0-30.0-32.1μm) and minimizing PTS (70-45.4-40.8μm).
    • A Pareto front demonstrated the trade-off between maximizing BIC and minimizing PTS, with a gradient of 37.1-70.0-67.7μm as an optimal solution.

    Conclusions:

    • A novel graded surface configuration can significantly enhance osseointegration.
    • Multiscale modeling provides a robust framework for optimizing implant surface design.
    • This approach enables patient-specific optimization for improved biomechanical environments and implant outcomes.
