About Dental Sand A1-A2
Not everyone knows why our material Dental Sand A1-A2 Resin has that name. You probably don't need to explain to dentists what the Vita scale is, but why A1-A2? Someone might think that there is a shade spread or the color of the material corresponds to the interval between A1 and A2, but this is not the case. In fact our material may look like A1 or A2 depending on the post processing protocol that you choose! This depends on the power of the UV illumination lamp and time of illumination. For example, on our Wanhao Boxman-1 UV camera 250W shade A1 is achieved at 20 minutes of illumination, and shade A2 at 40 minutes. This allows the dentists or dental technicians to achieve exactly the shade that they need in a particular case, using the same material!
