초록

목적: 본 연구에서는 치과용 CAD-CAM (computer aided design-computer aided manufacturing) hybrid 수복재료인 LAVA Ultimate와 VITA ENAMIC을 광중합 복합레진을 사용하여 수리할 때 표면처리방법(grinding, air abrasion with aluminum oxide, HF acid)과 접착재료(Adper Single Bond 2, Single Bond Universal)의 종류가 두 재료 사이의 전단결합강도에 어떠한 영향을 미치는지 알아보고자 하였다. 재료 및 방법: LAVA Ultimate와 VITA ENAMIC 시편을 30일간 $37^{\circ}C$의 인공타액(Xerova solution)에 보관하여 시효처리를 실시한 후 각각 SiC paper grinding한 것, grinding 후 air abrasion처리를 추가한 것, grinding 후 HF 처리한 것으로 분류하고 각각 no bonding, Adper Single Bond 2, 또는, Single Bond Universal 도포로 세분하여 9개의 group, 총 18개의 subgroup으로 나누어 실험을 실시하였다(N=10). HF 처리group에서는 도재시편을 대조군으로 추가하였다(N=10). 표면 처리 후 광중합 복합레진(Filtek Z250)을 각각의 시편에 부착하고 이를 1주일간 실온의 물에 침적시켰고 이후 전단결합강도를 측정하고 파절양상 및 표면처리 효과를 SEM으로 확인하였다. One-way ANOVA를 이용하여 group 간의 유의성을 분석하였고 사후 분석으로 Scheffe test를 실시하였다(${\alpha}=.05$). 결과: 실험 결과 접착재료 처리를 한 group들이 접착재료 처리를 하지 않은 group에 비해 모든 표면처리에서 더 높은 전단결합력을 나타내었으며, 표면처리만 시행한 group에서는 aluminum oxide air abrasion이 전단결합력의 증가에 약간의 영향을 미치는 것으로 나타났으나 통계적 유의성은 보이지 않았다. 결론: LAVA Ultimate와 VITA ENAMIC의 두 재료를 광중합 복합레진을 이용하여 수리를 실시할 경우 각각의 재료에 적합한 표면처리방법과 접착재료의 선택에 대한 연구가 더 필요할 것으로 사료된다. 특히 LAVA Ultimate의 경우 접착재료의 사용은 추천된다고 사료되었다.

Purpose: This study was performed in order to assess the effect of the surface treatment methods and the use of bonding agent on the shear bond strength (SBS) between the aged CAD-CAM (computer aided design-computer aided manufacturing) hybrid materials and added composite resin. Materials and methods: LAVA Ultimate (LU) and VITA ENAMIC (VE) specimens were age treated by submerging in a $37^{\circ}C$ water bath filled with artificial saliva (Xerova solution) for 30 days. The surface was ground with #220 SiC paper then the specimens were divided into 9 groups according to the combination of the surface treatment (no treatment, grinding, air abrasion with aluminum oxide, HF acid) and bonding agents (no bonding, Adper Single Bond 2, Single Bond Universal). Each group had 10 specimens. Specimens were repaired (added) using composite resin (Filtek Z250), then all the specimens were stored for 7 days in room temperature distilled water. SBS was measured and the fractured surfaces were observed with a scanning electron microscope (SEM). One-way ANOVA and Scheffe test were used for statistical analysis (${\alpha}=.05$). Results: Mostly groups with bonding agent treatment showed higher SBS than groups without bonding agent. Among the groups without bonding agent the groups with aluminum oxide treatment showed higher SBS. However there was no significant difference between groups except two subgroups within LU group, which revealed a significant increase of SBS when Single Bond Universal was used on the ground LU specimen. Conclusion: The use of bonding agent when repairing an aged LAVA Ultimate restoration is recommended.
