Abstract
Composite materials particularly suitable in the dental art as a tooth filling material including a polymer matrix, a metal, metal alloy, metal oxide particulate, or combinations thereof, in the presence or absence of colloidal silica, and a coupling agent to adhere the particulate to the polymer matrix. Adhesion can also be facilitated by cleaning and/or coating the particulates prior to incorporation into the polymer matrix. One or two paste systems of the composition with suitable initiators, accelerators, etc. can be formulated.
