title: Effect of metal fillers on some physical properties of acrylic resin.
abstract: Thermal conductivity of poly(methylmethacrylate) is low. Fillers of silver, aluminum, and copper particles at 25% concentration, increased thermal conductivity of poly(methylmethacrylate) by 4.53, 4.43, and 4.04 times, respectively. Although the compressive strength of poly(methylmethacrylate) increased with the addition of these fillers, tensile strength decreased. Silver and copper particles made the material radiopaque. Advantages of metal-filled acrylic resin denture bases are described.
