Development of domestic CAD/CAM blanks for dentistry
https://doi.org/10.33667/2078-5631-2024-28-21-25
Abstract
Zirconium oxide (ZrO2) occupies a significant place in the production of engineering materials due to its outstanding physicochemical stability. Advances in the stabilization of zirconium materials have opened up new horizons for their application, ranging from medicine to sophisticated aerospace technologies. Particular attention is paid to its role in CAD/CAM technologies in dentistry, which provide high precision and reduce treatment times.
The aim of this study is to develop and optimize methods for the production and consolidation of nanostructured zirconium oxide powders for CAD/CAM applications.
Materials and methods: High-quality zirconium oxide in the form of stabilized 3Y-TZP powder containing 3 mol. % yttrium oxide (Y2O3), which provides stabilization in the tetragonal phase, was used for the study. In addition, various additives such as polyethylene glycol (PEG) and polyvinyl alcohol (PVA), which serve as binders and plasticizers, were used to improve the agglomeration and sintering processes. Of course, CAD/CAM technologies occupy one of the first places in modern dentistry. Research and optimization of the production process of domestic CAD/CAM blanks made of zirconium dioxide will help to improve production technologies and improve their characteristics. The main focus of the study was on improving mechanical properties, such as density, hardness and resistance to cracking, which are key to the functional reliability of the material. The development of domestic CAD/CAM blanks, whose characteristics are not inferior to foreign analogues, will improve the quality of dental services and will contribute to import substitution in this area. The study of properties and their subsequent optimization emphasize the significant potential of this area, contributing to further scientific research and technological innovations, creating a foundation for future technological breakthroughs.
