The paper presents the results of studies of the strength of dental material; zirconium dioxide in terms of the needs of dentists. More and more frequently it happens that dentists require not only mean value (or scope) of strength of a given material as well as the analysis of its reliability under load. It seems that it is necessary each day while taking a decision on the material for the fully-ceramic crown or bridge if the element considering the properties assumed by the manufacturer is to meet the patient’s expectations. The aim of the paper is to evaluate the risk and to determine the parameters of distribution of the damage probability for zirconium dioxide specimens. The paper has been based on the results of studies of 3-point bending of cuboid beams. There has been presented a method of zirconium dioxide specimen treatment. It has been considered what effect on the scatter of the results is attributed to the cross-section of the specimens. There were determined characteristic stresses, for which 63% of the specimens will get destroyed.
