Abstract: Tissue engineering is a multidisciplinary research field that involves cell and molecular biology, material sciences, bioengineering, medicine, among others, that aim to restore or replace tissues. Predominant approaches include the design and procurement of scaffolds that provide adequate structural support for bone tissue. In the present work, an extension of the mathematical model of the reaction-diffusion type proposed by Svetlana V. Komarova et al. in 2003 of autocrine and paracrine interactions between osteoblasts and osteoclasts with biharmonic terms that allow calculating cell dynamics. A detailed study of the dynamics and stability of the population model was carried out, establishing the values of the control parameters of the proposed model, under Turing and Hopf instability. The model is solved using the improved Euler method and finite difference in two and three dimensions. The numerical results of the computational simulation describe the process of bone remodeling from the biological point of view. Subsequently, using the mathematical design process technique and 3D printing-assisted manufacturing (MDP-3DPAM), scaffolds were obtained that show a similarity with human trabecular bone tissue, based on polylactic acid (PLA), which were characterized by mechanical compression tests. We found that the mechanical resistance of our scaffolds has a viscoelastic behavior that does not occur in other scaffolds obtained from the numerical solution of the diffusion-extended Komarova model using the same method.
