摘要: In order to clarify the viscoelastic properties of four commercial resins for crown and bridge, dynamic shear modulus (G'), Knoop hardness (KHN), filler content, quantity unreacted substance thermal expansion were measured. The results as follows. G' (37 degrees C) each material ranged from 2.61-11.1 GPa, gradually decreased with increasing temperature. KHN (23 29.4 120, most significant correlation (0.999) was found between KHN. Of relationship among G', content substance, there a highly (0.980) content. coefficient linear-thermal (alpha) also 17.9-65.0 x 10(-6)/degree C (25-60 C), (-0.961) alpha meaningful. It can be presumed that temperature dependence is closely connected specific volume material, together an increase in
