Abstract

Purpose: Many studies have shown that airborne-particle abrasion of fiber post can improve the bonding strength to resin cement. But, airborne-particle abrasion may influence the property of fiber post. The purpose of this study is to evaluate the influence of airborne-particle abrasion on flexural strength of fiber post. Materials and Methods: Two fiber-reinforced posts; DT Light Post Size 2 (1.8 mm diameter, Bisco Inc) and RelyX Fiber Post Size 3 (1.9 mm diameter, 3M ESPE); were used in this study. Each group was divided into 3 subgroups according to different surface treatments; without pretreatment: $50{\mu}m$ aluminum oxide (Cobra$^{(R)}$, Renfert): and $30{\mu}m$ aluminum oxide modified with silica (Rocatec Soft$^{(R)}$, 3M ESPE). After airborne-particle abrasion procedure, three-point bending test was done to determine the flexural strength and flexural modulus. The diameter of each posts was measured to an accuracy of 0.01 mm using a digital micrometer. There was no diameter change before and after airborneparticle abrasion. The mean flexural moduli and flexural strengths calculated using the appropriate equations. The results were statistically analyzed using One-way ANOVA and Scheffe's post-hoc test at 95% confidencial level. Results: There was no significant difference on flexural strength between groups. Conclusion: In the limitation of this study, flexural strength and flexural modulus of fiber post are not affected by airborne-particle abrasion.

목적: 미세입자 분사마모 표면처리가 Fiber-Reinforced Composite (FRC) 포스트의 굴곡강도에 미치는 영향을 평가하는 것이다. 연구 재료 및 방법: 두 종류의 FRC 포스트 (DT Light Post, Size 2, Bisco Inc. / RelyX Fiber Post, Size 3, 3M ESPE)를 사용하여 표면처리에 따라 6개의 그룹으로 무작위 분류하였다. 표면처리를 위해 $30{\mu}m$ Rocatec Soft와 $50{\mu}m$ aluminum oxide를 사용하였다. 표면처리 후 편평한 5 mm 부분을 만능시험기로 3점 굽힘시험을 시행하여 FRC 포스트의 굴곡강도와 굴곡계수를 측정하고 통계분석하였다. 결과: FRC포스트의 미세입자 분사마모 표면처리가 FRC포스트의 굴곡강도와 굴곡계수에는 영향을 미치지 않음을 알 수 있었다. 결론: 임상가들이 FRC포스트에 대하여 미세입자 분사마모 표면처리를 하여도 포스트의 굴곡강도와 굴곡계수에는 영향을 미치지 않으면서 접착강도를 높일 수 있을 근거 중의 하나가 될 수 있을 것이다.
