- The paper studies the hardness of zirconium dioxide used in dentistry for the production of dental implants. The purpose of the study was to analyze the change of material microhardness after mechanical treatment and machining with subsequent firing. In total 30 zirconium dioxide samples were made, which were exposed to machining: diamond drill of high and low granularity, sandblasting and processing with zirconium dioxide disk. It was found that after machining without firing the hardness of material decreases by at least 26 %, and in some cases, even more in comparison with situations when regenerating firing is performed after processing. As a result of the study we came to a conclusion that additional processing of zirconium dioxide implants leads to heating of a material thus changing the structure of its surface, which can potentially cause changes of dental implants. If any clinical case requires additional processing it is preferable to use diamond grinding points with subsequent regenerating firing and sandblasting without additional firing.
