Abstract
Večina proizvajalcev dentalnih materialov v svojih certifikatih o kakovosti materialov podaja njihovo kemijsko sestavo, mehanske lastnosti, obdelovalnost in estetske karakteristike, medtem ko podatkov o toplotnih lastnostih ne zasledimo. V okviru magistrskega dela smo izmerili toplotne lastnosti petih izbranih, v stomatološki praksi vsakodnevno uporabljanih dentalnih materialov, izdelanih v laboratorijih slovenskih in mednarodnih podjetij. Meritve smo izvedli pri sobni temperaturi in na temperaturnem intervalu med 0 °C in 50 °C v skladu s standardom ISO 22007-2. V okviru dela predstavljamo posamezne inženirske metode določevanja toplotnih lastnosti materialov in standardi skupine ISO 22007. Izvedli smo kompleksno študijo in oceno delovanja naprave za določevanje toplotnih lastnosti Hot Disk TPS 2200, enega izmed najsodobnejših in najkakovostnejših instrumentov za določevanje toplotnih lastnosti.

Title:Determination of thermal properties of dental materials
Abstract:
Today the most manufacturers of dental materials in their certificates of quality of material give its chemical composition, mechanical properties, process ability in aesthetic characteristics while information about thermal properties are not observed. Within the master's work we carried out measurements of the thermal properties of five selected, in daily dental practice used, dental materials which were produced in the laboratories of Slovenian and international firms. 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. Within the work were presented the specific engineering methods for determination of the thermal properties of materials and standards from group ISO 22007. A complex study was preformed and evaluation of functioning of the device for modern and high-quality instrument for the determination of the thermal properties.

Keywords:thermal properties, dental materials, Hot Disk method, measurements of thermal conductivity
