|
The purpose of this study is to compare the effect of two types of polyetherketoneketone, press type and milling type, on the color change after layering step. The specimens without any treatment as the control group, experimental groups were divided into rocatec treated specimens for the silica coating on the surface, the opaque coated specimens after rocatec treated, the resin coated specimens after rocatec treated, the opaque coated specimens after rocatec treated and then resin coated specimen. The CIE L*, a* and b* values was measured using VITA Easyshade advance 4.0 and analyzed by one way ANOVA. There was a significant difference in color stability between press type and milling type polyetherketoneketone due to layering step. The L* values and b* values were increased by layering step, and color stability was better when resin was applied after rocatec treatment. It is considered that it is the best combination to proceed to a step of applying a resin included in a clinically acceptable range.
