National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Resin-Modified Glass-Ionomer Dental Cements Field of the Invention.

PB88185665

Publication Date	1988
Personal Author	Antonucci, J. M.; McKinney, J. E.; Stansbury, J. W.
Page Count	30
Abstract	Resin-modified glass-ionomer cements are provided comprising polyelectrolyte-based cements and compatible vinyl monomers and/or polymers. The composites can be further crosslinked by free-radical chemical or photochemical polymerization in addition to the usual acid-base type crosslinking of the glass-ionomer cement. Water-soluble monomers and polymers which are incorporated into glass-ionomer cements provide cement composites which are more resistant to brittle fracture and hydrolytic degradation than the conventional glass-ionomer cements. These hybrid cement composites bond directly to vinyl polymeric composites and tooth structure and demonstrate excellent resistance to microleakage.
