| Outline of Final Research Achievements |
As a result of the chewing simulation test in three different contact states in the ceramics versus the enamel abrasion examination, the amount of wear of opposing tooth enamel versus the glass ceramics and zirconia was influenced by the surface roughness in the reciprocating sliding motion. In addition, the amount of wear of enamel versus the glass ceramics and zirconia showed the possibility of wearing the pairing teeth rather than the enamel, regardless of the surface roughness in the repetitive collision motion. On the other hand, in order to investigate the degree of abrasion and surface roughness of materials and antagonist teeth before and after treatment depending on the presence or absence of bruxism during sleep, it was not possible to obtain statistical analysis results sufficiently from the lack of the number of subjects.
