FIELD: medicine.

SUBSTANCE: group of inventions relates to dentistry and particularly to a kit for preparing a dental restoration material, a composition obtained from such a kit, and a medical device containing such a kit. Proposed kit includes a first container containing a powder phase, comprising: from 15 to 98% by weight of the total weight of the powder phase of ultrafine calcium silicate particles, for which the d₁₀ value lies in range from 0.4 to 0.8 mcm, d₅₀ value lies in range from 0.7 to 2.9 mcm and d₉₀ value lies in range from 1.3 to 7 mcm; wherein d₁₀, d 50 and d 90 are determined by laser diffraction; from 2 to 35% of radio-opaque material by weight of total weight of powder phase; and a second container containing an aqueous liquid phase. Weight ratio of the powder phase in the set to the liquid phase in the set ranges from 2 to 5. Also disclosed is a dental composition obtained by mixing the entire contents of the first container with the entire contents of the second container in the above set, and a medical device representing an injection system and comprising said kit.

EFFECT: composition of the kit enables to obtain a dental restoration material from dental hydraulic cement containing ultrafine calcium silicate particles in the presence of a limited amount of water, so that the hydraulic cement quickly hardens, turning into a material having mechanical properties required for dental restoration, especially high compression strength.
