The present invention relates to a method for producing hydroxyapatite-bioglass macroporous material, to said materials, and to medical devices thereof.

The method comprises a step of preparation of an aqueous suspension of hydroxyapatite and bioglass with a porogenic agent, and subsequent sintering to achieve a macroporous biomaterial.

The macroporous structure of these materials enhances blood vessels and bone cells migration, allowing bone growth through the interior of the bone substitute, thereby increasing the rate of formation of new bone at the site of implantation. Therefore, these materials are advantageously used to produce medical devices, such as bone grafts that resemble the mineral phase of natural bone showing improved mechanical strength and osteoconductivity.

The biomaterials of the present invention are applicable in the medical area, in particular in bone regeneration and reparation techniques as bone grafts.
