Method for preparing a biomaterial based on hydroxyapatite, resulting biomaterial and surgical or dental use

摘要

A solid powder product with a Ca/P ratio of between 1.40 and 1.90 is prepared from tricalcium phosphate and tetracalcium phosphate. An aqueous solution containing calcium ions and phosphate ions with a Ca/P ratio higher than 0.20 and lower than 0.50 is prepared. The aqueous solution and the solid powder product and optionally water are mixed to obtain a mixture with a liquid/solid weight ratio of between 0.30 and 0.65 and a resulting paste with a Ca/P ratio of between 1.50 and 1.67.
