dc.description.abstract | Tissue engineering has recently gained popularity as an alternative to autografts to stimulate bone tissue
regeneration through structures called scaffolds. Most of the in vivo experiments on long-bony defects use
internally-stabilized generic scaffolds. Despite the wide variety of computational methods, a standardized protocol is required to optimize ceramic scaffolds for load-bearing bony defects stabilized with flexible fixations. An
optimization problem was defined for applications to sheep metatarsus defects. It covers biological parameters
(porosity, pore size, and the specific surface area) and mechanical constraints based on in vivo and in vitro results
reported in the literature. The optimized parameters (59.30% of porosity, 5768.91 m− 1 of specific surface area,
and 360.80 μm of pore size) and the compressive strength of the selected structure were validated in vitro by
means of tomographic images and compression tests of six 3D-printed samples. Divergences between the design
and measured values of the optimized parameters, mainly due to manufacturing defects, are consistent with the
previous studies. Using the mixed experimental-mathematical scaffold-design procedure described, they could be
implanted in vivo with instrumented external fixators, therefore facilitating biomechanical monitoring of the
regeneration process. | es |
