In this paper we describe an experimental study, reported inthis article are trial manufacture of composite tooth materialfrom unsaturated polyester as matrix and glass bead as filler andresults of experimental studies in its mechanical properties,abrasion properties, surface profile and micro-properties offracture.As a result of this series of tests and experiments, it wasfound that, with filling glass beads by 30 wt.%, abrasion quantityof the composite material falls to 1/4 of that of unsaturatedpolyester resin, and abrasion resistance is improved remarkably.By filling glass beads, tensile and bending strength, elongationand deflection become smaller. In terms of elastic modulus, thecomposite material has tendency to show increase in dry condition,while to show decrease in wet condition. It is fairly expectableto have composite artificial teeth having glass beads by 30 wt.%.
