ABSTRACT:
A composition useful as a restorative material includes a curable matrix with whiskers which preferably have a silicon dioxide containing coating thereon that are then silanized and may also include optional particulate filler of the type which may release fluorides. The polymeric matrix bonds more tightly to the whiskers due to the coating of silicon dioxide on the surface of the whiskers and the coaction between said silicon dioxide and the silane compound. Particles adhered to the whisker also enhance the mechanical properties by virtue of the whisker's surface being thereby roughened. A method of manufacture is also disclosed.
