| titleOfInvention | Dental impression material utilizing ruthenium catalyst |
| abstract | A composition for use as a dental impression material including a polymerizable telechelic oligomer or polymer curable by ring-opening metathesis polymerization, a filler system, and a ruthenium carbene complex catalyst, whereby the catalyst initiates ring-opening metathesis polymerization of the composition. The invention includes a paste/paste system in which a base paste includes the polymerizable telechelic oligomer or polymer and a filler system and in which a catalyst paste includes the catalyst dissolved in an inert solvent and a filler system. The telechelic oligomer or polymer may be, for example, a polydimethylsiloxane end-functionalized with norbornyl groups. The catalyst may be, for example, a ruthenium carbene complex with a ligand having a basicity higher than tricyclohexylphosphine. The composition of the present invention exhibits reduced sensitivity to sulfur impurities. |
