DENTAL MATERIALS BASED ON MONOMERS, ABLE TO DISCONNECT ON REQUEST Russian patent published in 2017 - IPC A61K6/00 A61K6/83 

FIELD: pharmacology.

SUBSTANCE: dental restorative material is proposed containing a thermolabile polymerizable compound of formula II: where Z¹ and Z² each independently represents a polymerizable group selected from vinyl groups, CH₂=CR¹-CO-O- and CH₂=CR¹-CO-NR²-, or a linking group selected from -Si(OR)₃, -COOH, -O-PO (OH)₂, -PO (OH)₂, -SO₂OH and -SH, wherein at least one Z¹ or Z² is a polymerizable group. Q¹ in each case is independently absent or is A (m+1)-valent linear or branched aliphatic C₁-C₂₀-radical that can be interrupted by -O-, -S-, -CO-O-, -O-CO-, -CO-NR³-, -NR³-CO-, -O-CO-NR³-, -NR³-CO-O- or -NR³-CO-NR³-. Q² in each case is independently absent or is a (n+1)-valent linear or branched aliphatic C₁-C₂₀-radical, which can be interrupted by -O-, -S-, -CO-O-, -O-CO-, -CO-NR³-, -NR³-CO-, -O-CO-NR³-, -NR³-CO-O- or -NR³-CO-NR³-. R, R¹, R² and R³ each independently is H or a C₁-C₇ alkyl radical; R⁴ - H or a C₁-C₁₀ alkyl radical; R⁵ - H, a C₁-C₅ alkyl radical, F or CN; R⁶ - H, a C₁-C₅ alkyl radical, F or CN. m and n are each independently 1, 2 or 3. It is also proposed to use the aforementioned compound of formula II for preparation of dental restorative material.

EFFECT: using of the group of inventions provides adhesive dental restorative materials that are polymerized, show good adhesion to the substrate, in particular, to the structure of a tooth or dental ceramics, and capable of disconnection from the substrate when heated, and that, therefore, are particularly suitable for production of adhesives or composite cements that are capable of separation on requested.
