Abstract

The paper aims to obtain prosthetic devices made of two different dental ceramics and characterized by infrared absorption spectroscopy (FITR), scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDX) and thermal analysis (TG- DTG-DTA). The two types of dental ceramics (VITA VM13 and IPS Style) were analyzed both in powder form, in the form before the firing process, and in the one resulting after this stage, sintered mass. The TG, DTG and DTA thermal analysis study identified the temperature range in which the ceramics are thermally stable and can be used in dental technique, with IPS Style ceramics showing a lower degree of decomposition.
