Glass fibres have been studied as strengthening </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>material added to polymethyl methacrylate. The purpose of this study was to evaluate dimensional change of acrylic resin plate after </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>glass fibre reinforcement. As a research subject is an acrylic resin plate of 65 </em><span style="font-size: 10pt; color: #231f20; font-style: normal; font-variant: normal;"><em>× </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>10 </em><span style="font-size: 10pt; color: #231f20; font-style: normal; font-variant: normal;"><em>× </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>2.5 mm with the number of 32 samples were </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>distributed randomly in 4 experimental groups. Each group consisted of 8 samples and control groups. Group 1: acrylic resin plate </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>and 1 sheet glass fibre; group 2: acrylic resin plate and 2 sheet glass fibre; group 3: acrylic resin plate and 3 sheet glass fibre. Control </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>group which was not given treatment. Dimensional change was measured by profile projector. The data was analyzed by One-Way </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>ANOVA and LSD test showed that there was significant difference in dimensional change (p &lt; 0.005). The conclusion suggested that </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>dimensional change of the acrylic resin plates after glass fibre reinforcement minimally done 1 sheet glass fibre.</em></span></span></span></span></span></span></span></span></span></span></span></span>
