| Summary: | <span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>Different types of fibers have been added to acrylic resin materials to improve their mechanical properties. The purpose of this </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>study was to know the transverse strength of the hybrid acrylic resins after glass fiber reinforcement with difference method. This </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>study used rectangular specimens of 65 mm in length, 10 mm in width and 2.5 mm in thickness. There were 3 groups consisting of </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>6 specimens each, hybrid acrylic resin without glass fiber (control), glass fibers dipped in methyl methacrylate monomer for 15 </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>minutes before being reinforced into hybrid acrylic resin (first method), glass fibers reinforced into a mixture of polymer powder </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>and monomer liquid after the hybrid acrylic resin was mixed directly (second method). All of the specimens were cured for 20 </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>minutes at 100</em><span style="font-family: TribuneRegular; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;">° <span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>C. Transverse strength was measured using Autograph. The statistical analyses using one way ANOVA and LSD </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>test showed that there were significant differences in transverse strength (p < 0.05) among the groups. The means of transverse </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>strength were 94,94; 118,27; and 116,34 MPa. It meant that glass fibers reinforcement into hybrid acrylic resin enhanced their </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>transverse strength compared with control. Glass fiber reinforcement into hybrid acrylic resin with differenciate method didn't </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>enhance their transverse strength.</em></span></span></span></span></span></span></span></span></span></span></span></span></span> |
