FIELD: medicine.

SUBSTANCE: group of inventions concerns dental composition, its application and kit with its use. Dental composition according to the invention comprises filler (F1) containing aggregated nanosized particles in an amount of 30 to 70 % by weight; filler (F2) comprising agglomerated nanosized particles in an amount of 1 to 20 % by weight; curable component (A1), which is a urethane (meta) acrylate with an amount of functional groups of at least 2 and having a molecular weight from 450 to 3,000 g/mol; curable component (A2) which is radically polymerizable by (meta)acrylate with amount of functional groups of at least 2 which differs from component (A1); and oxidation-reduction curing initiator system. In this case, the dental composition does not contain an unagglomerated and non-aggregated nano-sized filler in an amount of more than 10 % by weight, where w% is based on the weight of the total composition. Use of said dental composition as or for the manufacture of prosthetic crown(s), pon(s), inlay(s), onlay(s), veneer(s) and space-occupying filling material and a set of components for providing the patient with a dental restorative structure comprising said dental composition and at least one or all of the following: dental duplication material, dental cement, adhesive. Inventive cured by redox reaction composition is easily mixed and solidified to produce a material having high strength and abrasion resistance.

EFFECT: dental composition is particularly useful in quality or for production of permanent crowns and pons, inlays, onlays and veneers.
