DENTAL MATERIALS BASED ON MONOMERS HAVING DEBONDING-ON-DEMAND PROPERTIES

摘要

The invention relates to a dental material which comprises a thermolabile or photolabile polymerizable compound of the formula (I): [(Z1)n-Q1-X)]k-T-[Y-Q2-(Z2)n]l (formula (I)), in which T is a thermolabile or photolabile group, Z1 and Z2 each independently are a polymerizable group selected from vinyl groups, CH2=CR1-CO-O- and CH2=CR1-CO-NR2- or are an adhesive group selected from -Si(OR)3, -COOH, -O-PO(OH)2, -PO(OH)2, -SO2OH and -SH, with at least one Z1 or Z2 being a polymerizable group, Q1 independently in each case is absent or is an (m+1)-valent linear or branched aliphatic C1-C20 radical, which may be interrupted by -O-, -S-, -CO-O-, -O-CO-, -CO-NR3-, -NR3-CO-, -O-CO-NR3-, -NR3-CO-O- or -NR3-CO-NR3-, Q2 independently in each case is absent or is an (n+1)-valent linear or branched aliphatic C1-C20 radical, which may be interrupted by -O-, -S-, -CO-O-, -O-CO-, -CO-NR3-, -NR3-CO-, -O-CO-NR3-, -NR3-CO-O- or -NR3-CO-NR3-, X and Y in each case independently are absent or are -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 are H or C1-C7 alkyl radical, and k, l, m and n each independently are 1, 2 or 3.
