Area of Science:

  • Biomaterials Engineering
  • Dental Implantology
  • Materials Science

Background:

  • Increasing lifespan necessitates advanced biomaterials for implants.
  • Current artificial implants lack biomechanical equivalence to natural tissues.
  • Titanium and hydroxyapatite are common dental implant materials with complementary properties.

Purpose of the Study:

  • To design a functionally graded material (FGM) dental implant for improved integration and stress distribution.
  • To optimize implant design to minimize stress in both the implant and surrounding bone.
  • To enhance dental implant longevity and prevent bone resorption.

Main Methods:

  • Utilized the finite element method for implant design.
  • Employed optimization techniques to determine optimal material composition.

  • Investigated the biomechanical performance of a hydroxyapatite/titanium FGM implant.

    • Main Results:

    • Identified hydroxyapatite/titanium as the optimal material combination for FGM dental implants.
    • Demonstrated a significant reduction in maximum bone stress with the FGM implant.
    • Achieved approximately 22% and 28% stress reduction compared to titanium and stainless steel implants, respectively.

    Conclusions:

    • Functionally graded materials offer a promising approach for next-generation dental implants.
    • Hydroxyapatite/titanium FGM dental implants significantly improve stress distribution and bone integration.
    • This design advancement leads to enhanced implant performance and reduced risk of bone resorption.
