  • Dental materials based on compounds having debonding-on-demand properties
    Patent number: 9320686
    Abstract: The invention relates to a dental restorative material which comprises a thermolabile compound of Formula I: [(Z1)m-Q1-X)]k-T-[Y-Q2-(Z2)n]l??Formula I, in which T represents a thermolabile unit which contains at least one thermolabile group based on non-covalent interactions, Z1 and Z2 in each case independently represent a polymerizable group selected from vinyl groups, CH2?CR1—CO—O— and CH2?CR1—CO—NR2— or an adhesive group selected from —Si(OR)3, —COOH, —O—PO(OH)2, —PO(OH)2, —SO2OH and —SH, Q1 in each case independently is missing or represents an (m+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—, Q2 in each case independently is missing or represents an (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—, X and Y in each case independently are missing or represent —O—, —
