The invention discloses a preparation method of a novel bionic supporting material in
bone tissue engineering, belonging to the field of the
bone tissue engineering. The preparation method comprises the following steps of: using a natural
plant tissue as a template and preparing a
bioceramic or
bioactive glass porous bracket material with a bionic structure through processes of
carbonization, vacuum / pressure impregnation of an inorganic
sol, template removal by oxidation in the air, high temperature
sintering and the like. The porous bracket material prepared by the invention has favorable physicochemical and biological properties, particularly has a
plant tissue porous structure obviously characterized by tubular holes, wherein the structure is extremely similar to a
cancellous bone and has a
porosity of 70-95% and aperture range of 10-28 mu m. The unique porous structure of the porous bracket material can quicken the substance exchange speed outside and inside the bracket, is in favor of controlling the degradation speed of the bracket material and promoting the growth of new bones. The preparation method of the bionic bracket material of the
bone tissue engineering has wide application potential in the generation and repair fields of hard tissues of the orthopaedics, the
dentistry, the maxillofacial
surgery and the like.
