Evaluation of strontium-containing hydroxyapatite as bone substitute in sheep tibiae. [PDF]

open access: yes, 2019
With the advancement of research in biomaterials, it has been suggested that the best osteoconductivity of hydroxyapatite would be achieved if its crystal were closer to the structure, size and morphology of biological apatite, that is why nano ...
