Patent Actimins Nano-sized Bio-active glass, The diamater of bio-active mineral powder reaches 200-800nm, smaller than the near crown diameter of dentin tubule, so it can come deep into the dentin tubule quickly. And with specific surface area, it can react quickly and continuously, releases mineral bio-active component, and therefore remineralize the teeth and closure effectively. 

1. Actimins reacts with saliva, Na ions release, elevating pH into the range of 8-8.5, which is essential for hydroxyapatite(HAp) formation.

2. Si irons is released and one silicon-rich layer was formed, which attracts Ca ions and P ions.

3. New HAp crystal layer is formed to remineralize and repair the defect, even deep inside the dentinal tubules.
