Reinforcement of Dental Methacrylate with Glass Fiber after Heated Silane Application

[摘要] This study evaluated the influence of silane heat treatment and glass fiber fabrication type, industrially treated (I) or pure (P), on flexural and compressive strength of methacrylate resin bars (BISGMA/TEGDMA, 50/50%). Six groups(n=10)were created: I-sil: I/silanated; P-sil: P-silanated; I-sil/heat: I/silanated heated to 100°; P-sil/heat: P/silanated heated to 100°; (I: I/not silanated; and P: P/not silanated. Specimens were prepared for flexural strength(10×2×1 mm)and for compressive strength9.5×5.5×3 mm) and tested at 0.5 mm/min. Statistical analysis demonstrated the following for flexural strength(P< 0.05 ): I-sil:155.89±45.27BC; P-sil:155.89±45.27BC; I-sil/heat:130.20±22.11C; P-sil/heat:169.86±50.29AB; I:131.87±15.86C. For compressive strength, the following are demonstrated: I-sil:1367.25±188.77ab; P-sil:867.61±102.76d; I-sil/heat:1162.98±222.07c; P-sil/heat:1499.35±339.06a; and I:1245.78±211.16bc. Due to the impossibility of incorporating the stipulated amount of fiber, P group was excluded. Glass fiber treatment with heated silane enhanced flexural and compressive strength of a reinforced dental methacrylate.
