The invention relates to a dental material which comprises a thermolabile compound of the formula (I): [(Z 1 ) m -Q 1 -X)] k -T-[Y-Q 2 -(Z 2 ) n ] l , in which T is a thermolabile unit which comprises at least one thermolabile group based on non-covalent interactions, Z 1 and Z 2 each independently are a polymerizable group selected from vinyl groups, CH 2 =CR 1 -CO-O- and CH 2 =CR 1 -CO-NR 2 - or are an adhesive group selected from -Si(OR) 3 , -COOH, -O-PO(OH) 2 , -PO(OH) 2 , -SO 2 OH and -SH, Q 1 independently in each case is absent or is an (m+1)-valent linear or branched aliphatic C 1 -C 20 radical, which may be interrupted by -O-, -S-, -CO-O-, -O-CO-, -CO-NR 3 -, -NR 3 -CO-, -O-CO-NR 3 -, -NR 3 -CO-O- or -NR 3 -CO-NR 3 -, Q 2 independently in each case is absent or is an (n+1)-valent linear or branched aliphatic C 1 -C 20 radical, which may be interrupted by -O-, -S-, -CO-O-, -O-CO-, -CO-NR 3 -, -NR 3 -CO-, -O-CO-NR 3 -, -NR 3 -CO-O- or -NR 3 -CO-NR 3 -, X and Y in each case independently are absent or are -O-, -S-, CO-O-, -O-CO-, -CO-NR 3 - or -NR 3 -CO-, R, R 1 , R 2 and R 3 each independently are H or a C 1 -C 7 alkyl radical, k and l each independently are 0, 1, 2 or 3, and m and n each independently are 1, 2 or 3.
