Title:
DENTAL COMPOSITIONS COMPRISING ETHYLENICALLY UNSATURATED ADDITION-FRAGMENTATION AGENT
Document Type and Number:
WIPO Patent Application WO/2012/112350
Kind Code:
A3
Abstract:
Dental compositions are described comprising an addition-fragmentation agent comprising at least one ethylenically unsaturated terminal group and a backbone unit comprising an α, β- unsaturated carbonyl; at least one monomer comprising at least two ethylenically unsaturated group; and inorganic oxide filler. The addition-fragmentation agent is preferably free-radically cleavable. The addition-fragmentation agent preferably comprises at least two ethylenically unsaturated terminal groups, such as (meth)acTylate groups. In some embodiments, the addition- fragmentation agent has the formula: wherein R1, R2 and R3 are each independently Ζm,-Q-, a (hetero)alkyl group or a (hetero)aryl group with the proviso that at least one of R1, R2and R3 is Zm-Q-; Q is a linking group have a valence of m +1; Z is an ethylenically unsaturated polymerizable group; m is 1 to 6; each X1 is independently -O- or -NR4-, where R4 is H or C1-C4 alkyl; and n is 0 or 1. Also described are dental articles prepared from a dental composition comprising an addition- fragmentation agent and methods of treating a tooth surface.
