Title:
BONE REGENERATION MATERIAL KIT, PASTE-LIKE BONE REGENERATION MATERIAL, BONE REGENERATION MATERIAL, AND BONE BONDING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/020192
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a bone regeneration material kit, paste-like bone regeneration material, bone regeneration material, and bone bonding material containing microparticles that comprise a bioabsorbable polymer, and making it possible to promote the regeneration of a patient's own bone over the long term and to actualize a non-disintegrating property such that disintegration does not occur even upon contact with water in blood, body fluids, and the like after filling, together with making it possible to ensure the mechanical strength of the bone by compensating for bone defects or damage over the short term. The present invention is a bone regeneration material kit containing microparticles that comprise a calcium salt having inositol phosphate or a salt thereof adsorbed to the surface, microparticles that comprise a bioabsorbable polymer, and an aqueous medium.
