Ideally bone graft substitutes should be made of hydroxyapatite in its purest form, as this prevents trace elements from having a negative effect on bone ingrowth. Ossifi is produced from calcium phosphate in its purest possible form.
Unlike most other biphasic calcium phosphates, Ossifi is not just a mixture of hydroxyapatite and ß-tricalcium phosphate. Ordinary mixtures do not guarantee the exact distribution of elements. Ossifi is synthesized through a combination of hydroxyapatite and ß-tricalcium phosphate creating a new molecule. This composition has the advantage that the two elements are equally distributed over Ossifi without clustering, thereby reducing the risk of cavitation or fibrous ingrowth to almost zero.
