Abstract

Constructive features of tissue engineering scaffold with defect bone are defined. And based on the definitions and medical image 3D reconstructions as well as CAD technology, the constructing method for macrostructure of its interior features of tissue engineering scaffold with defect bone is presented, which is based on parametric expressions. And demonstrations of two constructing methods are given. Finally from calculations of the porosity, the structures of interior features are proven to meet the demand of porosity of tissue engineering scaffold with defect bone.
