Abstract
Alkoxides with polymerizable groups are single source precursors for organic-inorganic hybrid composites possessing good mechanical properties. Additional function groups of the alkoxides provide enhanced adhesion to other surfaces, such as dentin. The selection of specific organic monomers having functional groups that are responsible for enhanced properties of the organic-inorganic hybrid composites is important. Single source precursors containing the desired functional groups are condensed and polymerized into the organic-inorganic hybrid composites with enhanced properties which are particularly useful as dental composites.
