(author), Weinans, Harrie (author), Jahr, H. (author), Zadpoor, A.A. (author)An ideal bone substituting material should be bone-mimicking in terms of mechanical properties, present a precisely controlled and fully interconnected porous structure, and degrade in the human body to allow for full regeneration of large bony defects. However, simultaneously satisfying all these three requirements has so far been highly...journal article 2017
