[Comparative evaluation of traditional and speed sintering of dental ceramics based on zirconium dioxide]

This study analyzed the traditional and high-speed firing of dental ceramics based on zirconia. The types of furnaces for sintering zirconia, the basic principles of traditional, high-speed and super-speed firing, as well as the effect of the sintering protocol on the structure, physical, mechanical, optical properties, wear and marginal fit of zirconia were evaluated. The analysis showed that it`s necessary to develop a special optimal sintering technique using particular protocols in specific types of furnaces for each dental ceramic material based on zirconia, taking into account the composition and structure of the ceramics. To write this review, articles from the electronic databases of Medline, PubMed and the websites of dental journals were used.
