Abstract
An urgent task in modern restorative therapeutic dentistry is to make a decision in each specific clinical case, which is justified not only from the esthetic and medical, but also from the economic, as well as the biomechanical and ergonomic points of view. According to many authors, the key to the successful restorative treatment of hard tissue defects of any genesis is to understand the etiological causes and conditions of their occurrence, as well as to assess the size of the defect and the level of material and technical base of modern dentistry.Long-term results of esthetic restoration of teeth using the direct method with various composite materials indicated the admission of multiple errors and complications, such as inconsistency in the color and transparency of the filling; violation of the marginal adherence; and the appearance of marginal staining along the border of the composite material with the tooth tissues, both during and in various terms after treatment.In contrast to the direct method of restoration, the ceramic inlay is made indirectly. This allows reducing polymerization shrinkage, which in turn improves marginal adherence and reduces the frequency of caries recurrence.

Summary
Севбитов А.В., Енина Ю.И., Дорофеев А.Е., Ершов К.А., Пустохина И.Г. СРАВНЕНИЕ ПРОЧНОСТНЫХ ХАРАКТЕРИСТИК ПРЯМЫХ И НЕПРЯМЫХ РЕСТАВРАЦИЙ ЗУБОВ ПРИ ОДНООСНОМ СЖАТИИ. Залогом успешного восстановительного лечения дефектов твердых тканей любого генеза является понимание этиологических причин и условий их возникновения, а также оценка размеров дефекта и уровня материально-технической базы современной стоматологии. Отдаленные результаты эстетического восстановления зубов прямым методом различными композитными материалами указали на допущение множественных ошибок и осложнений, таких как несоответствие цвета и прозрачности пломбы, нарушение краевого прилегания, появление краевого окрашивания по границе композитного материала с тканями зуба, как во время, так и в различные сроки после лечения. Ключевыеслова : реставрация зубов; гибридная керамика; композиционный материал; краевое прилегание; одноосное сжатие; прочность. In contrast to the direct method of restoration, the ceramic inlay is made indirectly. This allows reducing polymerization shrinkage, which in turn improves marginal adherence and reduces the frequency of caries recurrence. Keywords : dental restoration; hybrid ceramics; composite material; marginal fit; uniaxial compression; strength
