Abstract

The bond strength of denture base resin and resin teeth, is an important factor in the long term prognosis of dentures. The purpose of this study is to find an appropriate combination of commercial denture base resin and artificial resin teeth according to shear bond strength. In this study, the shear bond strength of various denture base resins (Vertex RS(Dentimax Ziest, Holland), PERform(Hedent GmbH., Germany), SR IVOCAP(Ivoclar AG, Schaan, Liechtenstein)) and resin teeth (SR Orthosit PE(Ivoclar AG, Schaan, Liechtenstein), Trubyte Biotone(Dentsply, U.S.A.)) was evaluated. 1. In comparison of denture resin, the shear bond strength increased in the order of IVOCAP, PERform, Vertex RS. 2. In resin teeth, Trubyte Biotone showed higher strength, but there was no statistical difference between the groups. 3. According to loading direction, the lingual showed higher strength, but there was no statistical difference. 4. When using SR Orthosit PE, SR  IVOCAP showed significantly higher shear bond strength(p<0.05). 5. Fracture tendancy showed more cohesive fractures(59) than adhesive failures(13). IVOCAP showed the most superior results statistically. TrubyteBiotone showed the highest shear bond strength. When using the SR Orthosit PE, it is thought that IVOCAP would present the most superior results.
