Purpose: This study was conducted to examine the color stability of temporary prosthetic materials for dental CADCAM. Method: 2 kinds of existing acrylic resin temporary filling materials and 2 kinds of polymer prosthetic materials for dental CAD-CAM were used for testing, and five specimens respectively were absorbed in soy sauce, red pepper paste, and coffee. A Chroma Meter was used as analysis equipment. The color change of the specimens was observed to calculate ΔE value throughout 2 days, 3 days, 4 days, and 5 days and this was analyzed and the following result was obtained. Results: Snap’s ΔE value was bigger than Vipi block(p<0.05). Red pepper paste had the largest impact on the color change of resin(ΔE), followed by soy sauce and coffee(p<0.000). With the passage of time, ΔE value was inversely(-) related and decreased somewhat(p<0.000).
