The scaffold composition for regeneration of hard tissue having magnesium phosphate, scaffold for regeneration of hard tissue comprising the same and preparation methods thereof

摘要

The present invention relates to a regenerating hard tissue-regenerating support composition including magnesium phosphate, a hard tissue-regenerating support including the same, and a method for producing the same. The support according to the present invention is produced through a new process of producing a hard tissue-regenerating support by producing a three-dimensional molded body from paste consisting of a magnesium source and a viscosity increasing agent to be deposited in a hardening liquid and made into cement so that a cement reaction of magnesium phosphate-based powder having excellent biocompatibility and mechanical properties can be applied to a lamination molding technology. Accordingly, sufficient time for controlling a three-dimensional shape and a pore structure can be ensured so that the structure thereof can be precisely controlled, and a high temperature sintering process is not performed so that sufficient mechanical strength can be ensured. Moreover, the same has excellent bioactivity and biocompatibility. Consequently, a structural disadvantage of an existing hard tissue-regenerating ceramic support can be remarkably overcome, and basic conditions required for the support can be satisfied, so that the support can be functionalized and production costs can be reduced through the simplification of a process and the application of a heatless process.
