ABSTRACT
The mechanical strength of glass ceramics based on leucite and lithium disilicate, insufficient to replace extensive tooth gaps, their high brittleness and susceptibility to cracking, and thus limited clinical use, are arguments for making zirconium dioxide widely used in dentistry. Permanent restorations based on zirconium dioxide are currently an alternative to metalceramic structures, both in the reconstruction of qualitative and quantitative single tooth defects, and in the design of extensive, multi-segmented restorations based on natural teeth or bone implants. The high parameters of the mechanical strength of zirconium oxide prosthetic structures have been achieved by completely eliminating the glass component from the material structure. The group of oxide ceramics also includes ceramics based on aluminium (III) oxide, which is rarely used today. The aim of the study is to present and characterize the types of oxide ceramics taking into account the indications, possibilities and limitations of their clinical application, processing technology and the advantages and disadvantages of each types of oxide ceramics in the manufacture of all-ceramic permanent restorations.
