| Outline of Final Research Achievements |
The aim of this study was to develop a novel polymer-infiltrated ceramic network (PICN) material for mimicking tooth wear characteristics. The PICN was fabricated d by polymer-infiltration and its polymerization. The wear properties of the PICN was evaluated in a two-body wear testing machine. The wear volume of the PICN was higher than that of commercially available PICN and lower than that of zirconia ceramic. These results suggested that the PICN may be relatively similar to the wear properties of enamel.
