23 Jul Method for preparing engineering material of bone tissue and application
Abstract
This invention discloses a method for preparing bioactive glass bracket material with controllable degradability. The method comprises: filling calcium-containing glass granules into a mold, sintering at a high temperature to obtain three-dimensionally through connected porous sintered body, and heating the sintered body to the softening point of the glass to performing secondary sintering in the mold; or grinding calcium-containing glass granules to obtain glass powder, adding binder, dispersant and rheological agent to obtain slurry, soaking organic foam into the slurry, dehydrating, drying, heating to remove binder, dispersant and rheological agent, and sintering to obtain three-dimensionally through connected porous bracket with the same structure as the organic foam template. The degradability of the bracket material is controllable by adjusting the composition of the glass. The bracket material can be used as the bracket for cell growth in bone tissue engineering, and is nearer to real bone bracket than other sintered materials.
