Изобретение относится к стоматологии, в частности к технике металлокерамических многослойных протезов, проблемой для которых является обеспечение высоких эксплуатационных характеристик и эстетических параметров, свойственных естественным зубам пациента. Согласно изобретению соотношение между кристаллическими и аморфной (стекловидной) фазами в дентиновом слое должно быть в пределах от 1 : 5 до 1 : 3 (мас.), а в грунтовом слое - от 1 : 1 до 1,5 : 1 (мас.). Нанесенные на металл керамические покрытия выдерживают многократные нагревы и охлаждения в интервале температур 20 - 930 - 20oС (не менее 5 термоциклов) без нарушения целостности. Изменения коэффициента термического расширения керамических масс при повторных нагревах не превышает 5 • 10-7 1/oС. Предложенные протезы обладают высокой технологичностью, достаточно легко воспроизводимы, а по некоторым параметрам (например, пиропластичность) керамических масс они превосходят требования международного стандарта.The invention relates to dentistry, in particular to the technology of cermet multilayer prostheses, the problem for which is to ensure high performance and aesthetic parameters inherent in the patient's natural teeth. According to the invention, the ratio between crystalline and amorphous (glassy) phases in the dentin layer should be in the range from 1: 5 to 1: 3 (wt.), And in the soil layer from 1: 1 to 1.5: 1 (wt.) . Ceramic coatings applied to the metal withstand repeated heating and cooling in the temperature range of 20 - 930 - 20 o C (at least 5 thermal cycles) without violating the integrity. Changes in the coefficient of thermal expansion of ceramic masses during repeated heating does not exceed 5 • 10 - 7 1 / o С. The proposed prostheses are highly adaptable, easily reproducible, and in some parameters (for example, pyroplasticity) of ceramic masses exceed the requirements of the international standard.
