Abstract
Described herein is a method that comprises: —placing a bone material, containing hydroxyapatite and organic substances, in contact with an extraction liquid that gives rise to a first liquid phase, containing the organic substances and possibly impurities extracted from the bone material, and a second solid hydroxyapatite phase, containing the hydroxyapatite; and —separating the liquid phase and the solid hydroxyapatite phase. The extraction liquid is an aqueous extraction solution brought to a temperature between 150° C. and 300° C. and a pressure between 150 kPa and 350 kPa.

A method to manufacture a bone regeneration material, comprising:
- contacting a bone material containing hydroxyapatite and organic substances with an extraction liquid giving rise to a first liquid phase containing said organic substances and optionally impurities extracted from said bone material, and to a second solid hydroxyapatite phase containing said hydroxyapatite;
- and
- separating said liquid phase from said solid hydroxyapatite phase,
- wherein said extraction liquid is an aqueous extraction solution brought to a temperature between 150° C. and 300° C. at a pressure of between 1500 kPa and 3500 kPa, and wherein said separated solid hydroxyapatite phase forms said bone regeneration material.
