Description
Summary:The purpose of the study is to investigate several thermal properties of two metallic materials based on titanium (Ti6Al4V and Ti10Mo) used in the fabrication of dental implants. Materials and methods: the laboratory equipment on which the tests were performed is a horizontal dilatometer type L75HS. The experiment was conducted on cylindrical samples of implant alloy type Ti6Al4V and on Ti10Mo experimental alloy samples The sample was analyzed within a temperature range from 25 to 150° C. We used a model with differential scanning calorimeter manufactured by Netzsch Company, DSC Maya 202 equipment. Results and discussion: The calorimetric results we obtained showed a good stability of metallic materials at temperature variation. Calorimetric stability of materials in the temperature range between 30-90°C gives an advantage to implant titanium based materials, decreasing the risk of contamination of living tissues which come in contact with these materials. Conclusions. Both the expansion of Ti6Al4V alloy and Ti10Mo alloy decreases 3 to 5 times at temperatures between 30 and 70° C and 2 to3 times at higher temperatures if the material is subjected to a preliminary thermal treatment.
