Customization and numerical simulation of a cranial distractor using computed axial tomography (CAT)

Abstract

The main objective of this research is to obtain a useful computational model to know the mechanical response of a cranial distractor which is widely used in patients who have been affected by osteogenesis in craniosynostosis. As a part of an optimization of this model, the parametric parts and the assembly will be modified in order to adjust the system to the Mexican anthropometry. The research considers the influencing of the osteogenesis and the cranial deformation in childrens and adults, trying to recover the best shape from the cranial affected zone. Therefore, an engineering approach will be applied and the analysis of each one of the assembled parts, considering the specific geometry and mechanical properties of the commercial models. It will be reported in the context of numerical tests. It will allow the evaluation of the structural integrity and the customization. It aims to develop the design and finite element analysis of an adjustable vertical, horizontal, sagittal and occlusal vectors external distractor system. Two proposals that arise design by performing a device made in materials and manufacturing cost economize, but which in turn is reliable and meets the general requirements for patient treatment.
