Comparison the Tensile and Transverse Strength between the Biostar Machine Sheets and Heat-Cure Acrylic Resin

The Biostar foils (Duran^®) used a substitute material to the heat cure acrylic in splint therapy. Dentists often prefer to make and deliver a splint shortly (1 to 2 hours) rather than having them fabricated in a laboratory when treating temp or mandibular joint disorders patients. The Duran^® became widely used and popular, the wear resistant and strength of the splint materials are the most important properties that improve the splint therapy. The study compared the tensile and transverse strength of the (Duran^®) Biostar foil and heat-cure acrylic resin. 40 samples were constructed in total, 20 samples for heat cure acrylic resin and 20 samples for Biostar foils. The result showed Duran sheets have the greatest mean values of transverse strength and tensile strength compared to heat cured resin
