| บทคัดย่อ: | The purpose of this study was to evaluate the dynamic viscoelastic properties of experimental silicone soft lining materials, Silastic® 4-4210 reinforced with silica fillers. Storage modulus (E'), loss modulus (E") and damping factor (tan δ) were determined using mechanical analyzer under a deformation strain level of 0.27% at test frequency and a temperature range of 1 Hz and 0 to respectively. The degree of silica dispersion was also studied using a field emission scanning electron microscopy (FE-SEM). ANOVA and Tukey's HSD test results indicated that the prepared silicone elastomers provided a significantly greater factor, but less storage modulus than GC Reline Soft and Tokuyama Sofreliner Tough (p<0.001). The storage moduli, loss and damping factor of the experimental silicone elastomers increased with increasing amounts of fumed silica. In conclusion, experimental silicone elastomers revealed acceptable dynamic viscoelastic properties to be used as denture soft lining materials. |
