Abstract:
A dental impression material which comprises a pre-polymer formed by reacting a polyol or combination polyester polyol with a diisocyanate, and then with a hydroxyacrylate or hydroxymethacrylate; along with a metal catalyst, plasticizer, photosensitizer, reducing agent, filler and other additives. The essential characteristics of the polymer portion that makes the system work are that it is a long-chain aliphatic polyester-polyurethane molecule, which when endcapped with hydroxy arcylate moieties, is photo-polymerizable to yield a tear-resistant, highly flexible, medium-durometer elastomer, suitable for use as a dental impression material.
