Computational Analysis of the Mechanical Properties of Ta/Cu Nanocomposite Dental Implants: On the Role of Incoherent Interfaces

Abstract In recent years, tantalum (Ta)-based nanostructured dental implants have been widely utilized considering their exceptional biocompatibility, bioactivity, and biomechanical properties. Despite advantages, the mechanical properties of Ta are higher than those adjacent jawbone, weakening bone structure. It has demonstrated that soft antibacterial additives such as copper (Cu) nanoparticles can tune features Ta-based to be similar bone. However, a noticeable gap in this research area is lack computational model explore interfacial load transfer through curved interfaces Ta/Cu nanocomposites. Accordingly, series molecular dynamics simulations employed survey microstructural evolution nanocomposites subjected uniaxial tensile loading condition at body temperature. Additionally, provide complete picture contribution Cu results, mechanisms governing plastic deformation nanocomposite models with fine-grained coarse-grained matrix systematically examined during process. summary, work provides comprehensive simulation role dislocation networks, twin formation, mutual interactions on extent zone various models.
