국산 복합레진의 전단결합강도 및 중합수축응력 비교

Abstract

The aim of this study was to evaluate the shear bond strength and shrinkage stress of various domestic composite resins. In this study, nine domestic composite resins from various manufacturers, Any-comTM (Mediclus, Chungju, Korea), Charmfil®Plus (Dentkist, Gunpo, Korea), DenfilTM (Vericom, Anyang, Korea), ESCom 100® (Spident, Incheon, Korea), Hanfil® (Han Dae Chemical, Seoul, Korea), Nexcomp® (Meta® Biomed, Cheongju, Korea), Transcen® (Nexobio, Cheongju, Korea), Xsfil® (B&E Korea, Gwangmyeong, Korea), Zircos-Com® (Bioden, Seoul, Korea) was set as experimental groups and Filtek Z-250TM (3M ESPE, USA) was set as control. As a result, ESCom 100®, Charmfil® Plus and Hanfil® showed shear bond strength similar to Filtek Z-250TM. Other domestic composite resins showed lower shear bond strength than Filtek Z-250TM (p < 0.05). In shrinkage stress, Filtek Z-250TM showed the lowest value compared to other domestic composite resins (p < 0.05).
