Abstract
This study was performed to investigate the color stability and shear bond strength of denture repair resins. The denture base resins used in this study were Premium Super-20(Lang Dental Mfg. Co.,. U. S. A.), as heat curing resin, Triad VLC
Denture Base(Dents-ply/York Division, U. S. A.), Triad Reline Material (Dents-ply/York Division, U. S. A), Repair Acrylic Lang Dental Mfg. Co., Inc.,. U. S. A.), Toughron Rebase (Miki Chemical Product, Kyoto, Japan), and Tokuso Rebase(Tokuyama Soda Co., Ltd., Japan) as denture repair resin. After fabrication of specimens, they stored for 20 months, then color changes and shear bond strength were measured by colorimeter(Model TC-6FX, Tokyo Denshoku Co.) and Instron Universial Test Machine @ES The results were as follows: @EN 1. There were changes of L*, a*, b* and DE* in Triad VLC Denture Base after 20 months. 2. There were changes of a* in Toughron Rebase and Tokuso Rebase, and b* in Tokuso Rebase after 20 months. 3. The shear bond strength of Repair Acrylic and Toughron Rebase were higher than that of Tokuso Rebase and Triad Reline Material.
