摘要: Abstract The work proposes the development of heterogeneous bio-implants with aim to minimize stress shielding effect and enhance bone ingrowth. Stress in implant can be minimized by reducing overall stiffness implant, which is achieved here varying material based on distribution across prosthesis. To increase stability simultaneous enhancing osseointegration shielding, design prosthesis graded porosity having radial, axial mixed (simultaneous radial axial) variations. Static analysis for variation models consolidation are performed. After comparisons results among different models, model was observed deliver results.
