실라노 펜의 적용이 장석계 도재 및 지르코니아와 레진의 전단결합강도에 미치는 영향 = The effect of Silano-pen on the shear bond strength of resin to feldspathic porcelain and zirconia

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study is to evaluate the effect of applying Silano-pen to feldspathic porcelain and zirconia on shear bond strength with composite resin. Materials and methods: Feldspathic porcelain and zirconia specimens were produced into 30 per each 2 mm thick and 12 mm in diameter and their surface was made smooth and even and then embedded in acrylic resin. The specimens were divided into each Group F (Feldspathic porcelain) and Group Z (Zirconia), (1) Hydrofluoric acid etching and silane (F1 & Z1), (2) Silano-pen and silane (F2 & Z2), (3) Hydrofluoric acid etching and Silano-pen, silane (F3 & Z3). After surface conditioning, substrate surfaces of the specimen were examined by SEM. Composite resin cylinders (2 mm high, 3 mm in diameter)were bonded to specimen and shear bond strength between ceramic and composite resin was measured by using universal testing machine. The measured values were statistically analyzed by using two way ANOVA and Tukey's multiple comparison test (${\alpha}=.05$). Results: In the scanning electron micrograph of the treated ceramic surface, Group F2 and F3 appeared the high roughness and Group Z3 appeared the highest density of silica particle. In Feldspathic porcelain, the result of measuring shear bond strength showed that Group F3 was measured to be highest and Group F1 was measured to be lowest but there was no statistical significance among Groups. In zirconia, Group Z3 was measured to be highest and Group Z1 was measured to be lowest and there was statistical significance among Groups (P<.05). Conclusion: In zirconia, applying hydrofluoric acid etching and then Silano-pen and silane is effective for composite resin adhesion.

연구 목적: 본 연구의 목적은 장석형 도재와 지르코니아에 Silano-pen의 적용이 복합레진과의 전단결합강도에 미치는 영향을 알아보고자 하는 것이다. 연구 재료 및 방법: 장석형 도재와 지르코니아를 지름 12 mm, 두께 2 mm 크기로 각각 30개씩 제작하여 표면을 고르고 평활하게 한 후 아크릴 레진에 포매 하였다. 각각 Group F와 Group Z로 나눈 후, (1) Group F1과 Z1은 불산 에칭과 실레인, (2) Group F2와 Z2는 Silano-pen과 실레인, (3) Group F3와 Z3는 불산 에칭과 Silano-pen, 실레인을 적용시켰다. 표면 처리 후, 각각의 시편의 표면을 주사전자현미경으로 관찰하였다. 높이 2 mm, 직경 3 mm의 복합레진을 붙여 광중합 하고 만능시험기를 이용하여 세라믹과 복합레진간의 전단결합강도를 측정하였다. 측정값을 Two way ANOVA와 Tukey's multiple comparison test을 사용하여 통계 분석 하였다(${\alpha}=.05$). 결과: 주사전자현미경의 관찰에서 Group F2와 F3에서 가장 거친 표면을 볼 수 있었으며, Group Z3에서 실리카 입자의 분포밀도가 가장 높았다. 장석형 도재에서는 전단결합강도 측정 결과 Group F3가 가장 높게 측정되었고 Group F1이 가장 낮게 측정되었지만, Group간에 통계학적 유의성은 없었다. 지르코니아에서는 Group Z3가 가장 높게 측정되었고 Group Z1이 가장 낮게 측정되었으며, Group간에 모두 통계학적 유의성이 있었다. 결론: 지르코니아에서는 불산 에칭의 적용 후 Silano-pen과 실레인의 적용이 복합레진 접착에 효과적이다.
