An overview of multilayered dental ceramics based on zirconium dioxide is presented. Classifications of dental ceramics based on zirconium dioxide and types of multilayer billets made of zirconium dioxide are considered. Examples of companies producing multilayered zirconium dioxide are given, and the strength and aesthetic properties of the different layers of multilayered blanks are described. Introducing a coloring additive does not affect the mechanical strength of multilayered zirconium dioxide. An increase in the content of yttrium oxide in the composition of multilayered zirconium dioxide increases transparency but decreases mechanical strength. Multilayered ceramics with a higher degree of transparency have poorer physical and mechanical properties than less transparent materials. Sandblasting reduces the mechanical strength of multilayered zirconium dioxide. If the layers of multilayered zirconium dioxide differ in color but have the same structure, then the strength indicators of each layer of the multilayered billet are at the same level. However, if the layers of multilayered zirconium dioxide differ in structure, then their strength within one billet will differ. The advantages and disadvantages of multilayered dental ceramic blanks based on zirconium dioxide are described. The prospects of using multilayered zirconium dioxide dental ceramics in Russia are discussed.

Представлен обзор по многослойной стоматологической керамике на основе диоксида циркония. Рассмотрены классификации стоматологической керамики на основе диоксида циркония и виды многослойных заготовок из диоксида циркония. Приведены примеры фирм, выпускающих многослойный диоксид циркония. Описаны прочностные и эстетические свойства разных слоёв многослойных заготовок. Указано, что введение окрашивающих добавок не влияет на механическую прочность многослойного диоксида циркония. Увеличение содержания оксида иттрия в составе многослойного диоксида циркония приводит к увеличению прозрачности, однако при этом снижается механическая прочность. Многослойная керамика более высокой степени прозрачности обладает худшими физико-механическими свойствами, чем менее прозрачные материалы. Пескоструйная обработка приводит к снижению механической прочности многослойного диоксида циркония. Если слои многослойного диоксида циркония различаются по цвету, но имеют одинаковую структуру, то показатели прочности каждого слоя многослойной заготовки находятся на одном уровне, однако если слои многослойного диоксида циркония различаются по структуре, то их прочность в пределах одной заготовки будет разной. Приведены преимущества и недостатки многослойных заготовок стоматологической керамики на основе диоксида циркония. Уделено внимание перспективам применения многослойной стоматологической керамики на основе диоксида циркония в России.
