DENTAL COMPOSITIONS, BLANKS FOR DENTAL PROSTHETICS AND METHODS Russian patent published in 2015 - IPC A61F2/00 A61K6/02 A61K6/08 A61K6/83 

FIELD: medicine, pharmaceutics.

SUBSTANCE: group of inventions relates to field of medicine and can be used for dental prosthetics. Dental composition contains polymerisable resin, which has ethylene-unsaturated group, as well as thermally activated initiator, dissolved in resin, and inorganic filling agent, mixed with resin, in amount, larger than approximately 60 wt % of composition weight. Initiator is activated at temperature from approximately 100°C to approximately 150°C with formation of free radicals. Initiator does not induce formation of compounds, initiating formation of free radicals in amounts, sufficient for inducing polymerisation, at temperatures below approximately 100°C. Filling agent represents nanoclaster and has surface area at least 65 m² per gram of filling agent. Blank for dental prosthetics, method of its manufacturing, and set for prosthetics are also disclosed.

EFFECT: group of inventions provides obtaining composite blank, which possesses considerably larger strength and wear resistance, as well as has better aesthetic characteristics.
