Abstract

Today almost all manufacturers of dental materials in their certificates of quality of material give its chemical composition, mechanical properties, process ability in aesthetic characteristics while informations about thermal properties are not available.
Within the work measurements of the thermal properties of five selected, in daily dental practice used, dental materials which were produced in the laboratories of Slovenian firms and high education institutions have been carried out. Measurements were carried out at room temperature, and in a temperature range between 0 °C and 50 °C in accordance with standard ISO 22007-2.
The specific engineering methods for determination of the thermal properties of materials and standards from group ISO 22007 will be presented. A complex study was preformed and evaluation of functioning of
the Hot Disk TPS 2200 device, modern and high-quality instrument for the thermal properties determination, was carried out.
