Numerical Investigation on Performance of FGM Dental Implant

The primary aim of this work is to reduce stress within the implant-bone interface by using a unique class of inhomogeneous materials known as functional gradient materials (FGM). To achieve this objective, we have developed a comprehensive three-dimensional model encompassing a dental implant and its surrounding tissue (cortical and cancellous bones). Our study involves an extensive analysis of dental implants constructed from various materials, including both homogenous and FGM substances, using the finite element method. The material properties of the FGM dental implant are precisely defined based on coordinate points within a user-defined material subroutine (UMAT) integrated into the widely-used commercial software ABAQUS/Standard. This approach allows for tailored characterization of FGMs, offering a promising avenue for improving the durability and performance of implant-bone systems. In summary, this research endeavors to enhance the reliability and longevity of dental implants through the innovative application of functional gradient materials and advanced computational techniques.
