Finite Element Analysis of the Bionic Tissue Engineering Scaffold for the Defect Cranium
The relationship between the porosity and the mechanical property was still a bottle-neck in bone tissue engineering scaffold.Porosity increasing may reduce the scaffold strength.In order to solve the contradiction,the idea of enhancing the mechanical properties by controlling the scaffold porosity was proposed in this paper.Using reverse engineering technology,5 different porosity cranium scaffolds were first established.Their FE models were built through FE surface preprocessing and volume fitted meshing.According to results of static analysis,the displacements and stresses of the 5 porosity scaffolds were compared and discussed and it indicated that the 36%porosity bionic scaffold have good porous level and mechanical properties.
