    <p>Целью данного обзора является определение положительных и отрицательных качеств и свойств блоков из диоксида циркония разных поколений, а именно 3Y-TZP, 5Y-TZP, 4Y-TZP. &#13;
Материалы и методы. Проведен систематический обзор литературы в электронных базах Google Scholar и Pubmed. Рассмотрены статьи, содержание которых основано на изучении механо-оптических и физико-химических свойств блоков из диоксида циркония 1, 3 и 4 поколения, их применение в практике.&#13;
Результаты. В ходе анализа было рассмотрено 57 статей, из них выбрано 47 из Pubmed и 10 из Google Scholar. После отбора статей по критериям суммарное количество исследований составило 27. В исследованиях оценивались механические и оптические свойства разных поколений блоков из диоксида циркония.&#13;
Вывод. Применение в стоматологической практике керамики из диоксида циркония, стабилизированного иттрием, разных поколений дает возможности получения качественных результатов при изготовлении и установке коронок, протезов, виниров и других ортопедических конструкций. Говоря про физико-механические и оптические свойства, следует заметить, что каждое поколение имеет разные показатели. Специалисты должны быть осторожны при выборе керамики из диоксида циркония, так как оптические свойства не всегда являются решающим фактором при выборе материала для изготовления  несъемных конструкций.</p>

    <p>The aim of this review is to determine the positive and negative qualities and properties of zirconium dioxide blocks of different generations, namely 3Y-TZP, 5Y-TZP, 4Y-TZP. &#13;
Materials and methods. A systematic literature review in the electronic databases Google Scholar and Pubmed was conducted. The articles whose content was based on mechano-optical and physicochemical properties of zirconium dioxide blocks of 1, 3 and 4 generations and their application in practice were considered.&#13;
Results: 57 articles were reviewed during the analysis, of which 47 from Pubmed and 10 from Google Scholar were selected. After selecting the articles according to the criteria, the total number of studies was 27. The studies evaluated the mechanical and optical properties of different generations of zirconia blocks.&#13;
Conclusion: The use of yttrium-stabilized zirconium dioxide ceramics of different generations in dental practice provides opportunities to obtain quality results in the fabrication and placement of crowns, dentures, veneers and other prosthetic structures. Speaking about physical, mechanical and optical properties, it should be noted that each generation has different indicators. Specialists should be careful when choosing zirconium dioxide ceramics, as optical properties are not always a decisive factor when selecting a material for fabrication of fixed structures.</p>
