DENTAL COMPOSITIONS CONTAINING ETHYLENE-UNSATURATED ADDITION-FRAGMENTATION AGENT Russian patent published in 2016 - IPC A61K6/83 

FIELD: medicine, pharmaceutics.

SUBSTANCE: group of inventions refers to dentistry and concerns a dental composition, and a method for using it. The dental composition contains an addition-fragmentation agent of formula (I): wherein each R¹, R² and R³ independently means Z_m-Q-, (hetero)alkyl group or (hetero)aryl group provided at least two of R¹, R² and R³ represent Z_m-Q-; Q represents a binding group having a valence number m+1; Z represents ethylene-unsaturated polimerised group; m means 1-6; each X¹ independently represents -O- or -NR⁴-, wherein R⁴ represents H or C₁-C₄alkyl; and n means 0 or 1; at least one monomer containing at least two ethylene-unsaturated groups; and an inorganic oxide excipient. A method of processing a tooth surface involves applying the above composition on the tooth surface in the individual's mouth, and hardening the above composition.

EFFECT: using the group of inventions provide lower load deflection and/or reduced contraction with maintaining the adequate mechanical properties and hardening depth.
