Title: ABSORBABLE BONE IMPLANT MATERIAL AND METHOD FOR PRODUCING THE SAME
Abstract:
The invention relates to absorbable bone implant material produced from a powder component containing hydroxylapatite; and a liquid. Said powder component of the implant material essentially consists of a mixture of hydroxylapatite powder and calcium sulphate powder. The hydroxylapatite powder consists of synthetically produced, precipitated, highly pure crystalline nano-particles with a crystal size of 10-20 nm in width and 50-60 nm in length. The specific absorbent BET surface area of the nano-crystals is preferably 100-150m2/g.
