CALCIUM PHOSPHATE/BIODEGRADABLE POLYMER HYBRID MATERIAL, METHOD FOR PRODUCING SAME, AND IMPLANT USING THE HYBRID MATERIAL

摘要

PROBLEM TO BE SOLVED: To solve problems of a calcium phosphate/biodegradable polymer hybrid material that introduced polylactic acid is dissolved and the three-point flexural strength deteriorates within a short period of 28 days in a solubility test under a pseudo living body fluid environment and the preparation period for the enzyme polymerization method is long considering that it takes 6 months in the generation of new bone.

SOLUTION: The calcium phosphate/biodegradable polymer hybrid material is prepared by immersing a calcium phosphate porous material into solution including a biodegradable polymer, performing an ultrasonic treatment or a suction treatment, and annealing. The material is increased in strength and its preparing period can be shortened to solve problems of known enzyme polymerization method.
