Easy-to-use and easy-to-handle dental materials having improved rheological properties

Abstract From the Canadian patent

Dental materials are provided comprising Component i) which is a hydrogen , bondable compound that is a polymer having a molecular weight greater than about 10,000, and Component ii), which is a hydrogen bondable bridging compound. One of Components i) and ii) contains 2 or more hydrogen-bond donor sites per compound, and the other of Components i) or ii) contains 2 or more hydrogen-bond acceptor sites per compound which hydrogen-bond acceptor sites , are not capable of also acting as hydrogen-bond donor sites. Components i) and ii) are present in an amount sufficient to exhibit at least 10 % higher Relative Viscosity, and optionally at least one of i) or ii) is polymerizable. If the …
