To evaluate toothbrush abrasion of high filler containing resin for crown and bridge, water absorption, volume of abrasion, abrasion resistance and surface roughness were determined. The results were as follows:
1. In water, absorption was increased in the order of Estenia enamel (EE), Estenia dentin (ED), Herculite XRV enamel (XE), Herculite XRV dentin (XD), ArtGlass enamel (AE) and ArtGlass dentin (AD).
2. The amount of abrasion was increased in the order of EE, AE and XE (Enamel Body), ED, XD and AD (Dentin Body).
3. In evaluation, abrasion resistance was increased in the order of EE, ED, AE, XD, XE and AD.
4. The surface roughness at the end of the experiment was increased in the order of XE, XD, ED, AD, EE and AE.
