| 内容記述 | As the demand for aesthetic restorations has increased in the past few years, tooth color materials have been used frequently in posterior teeth. Ceramics are widely used as dental restorative materials. The CELAY system that creates a ceramic inlay by a milling technique has been developed and introduced recently. The purpose of this study was to investigate the marginal adaptation and internal fit of ceramic inlays made using the CELAY system. Twenty extracted upper premolars were used. Only one clinician prepared all twenty box-shaped class II (MO) cavities to make the cavities uniform. The fabricated ceramic inlay that each of five ceramic inlays made by four clinicians whose clinical experience period differed was luted in the individual cavity with a dual-cured composite resin cement. Then all of them were cut mesio-distally through the center of the inlay. The cut surface of the specimens were observed under a profile projector. Marginal adaptation and internal fit were defined as inter facial distances between a ceramic inlay and cavity wall, and measured at nine preselected points. The following results were obtained; 1) The average gap width for all measured points was 170.2±111.8μm. 2) Statistical analysis showed that there were no significant differences among the nine preselected points. But there were significant differences (P<0.01) among the operators. 3) The fitness of the ceramic inlay to the cavity wall had decreased in the order of the central cavity wall, the margin of the cavity and line angle of the cavity, when compared with the nine measuring points. It may be concluded that if the operator is greatly experienced in the ways of the CELAY system he can reduce operating time and can improve adaptation. | |||||||
