Comparing meshless methods with the finite element method for applica- tion of a bio-inspired remodelling algorithm intended to design bone scaf- fold

Resumo

The design of bone scaffold involves the consideration of stress shielding which occurs when the
Young’s modulus of the implant is higher than the Young’s modulus of the bone it is replacing and therefore, bone
decay occurs in the surrounding tissue. It is therefore very important that the material is adequately adapted to the
properties of the surrounding tissue to allow for appropriate load transfer between the bone and the implant. There
are several studies to evaluate the occurrence of proper bone ingrowth in scaffold using bone remodelling models
and most studies assume an already existing scaffold design.
This work aims at combining meshless methods combined with the bone remodelling algorithm as a way to
develop optimized functional gradients of infill density for bone scaffold with the intent of obtaining mechanical
properties in the scaffold that will be compatible with bone tissue.
