Our factory developed H-R-A (Height Resistance of Abrasion) power,and applied it to the production of multi-layers synthetic resin teeth.The study for using of organic ontology materials to increase teeth abrasion resistance opened a new road,and this technology is unique in the world.

Product main features:

1.The mechanical property differences between inorganic grits and organic made it difficult to grind and rectify and caused low polishing performance;

2.The interface effect caused low transparency;

3.The discrepancies of hardness and thermal stress in the oral evironment caused dark pigments due to roughness of teeth surface

We adopt internaltional standards to do teeth abrasion test for addition of HRA material or not,addition of HRA materials that abrasion value of synthetic resin teeth is 22.95mg,on the contrary,is 77.75.Through calculation,teeth wear-resisting degree will enhance 3.4 times than before.
