Hydroxyapatite structure. Hydroxyapatite planar view of (001) face (a). There are two positions available for calcium ions as labeled CaI and CaII. Hydroxyapatite calcium channel (b). The CaII cations at the position z = ¼ and ¾ form triangles, these triangles are rotated in each successive mirror plane by 60°, giving rise to calcium channels that are occupied by hydroxyl groups in HAp. Calcium is in green and hydroxyl in pink
