Abstract
A silane treated high purity chopped quartz fiber reinforced dental composite material having increased viscosity for improved handling ability, reduction in porosity, elimination of edge-void defects and improved reestablishment of interproximal contacts. The fiber ductility specifically permits bending and confirmation within small geometrical boundaries to approximate continuous fiber strengths without incurring excessive breakage or voids.
Claims10
A high-viscosity dental material, comprising:
- a resin of a polymerizable polymer with flowable characteristics;
- and
- a plurality of chopped-glass fibers mixed directly into the resin such that the resin bonds directly to a surface of the chopped-glass fibers, wherein each of the chopped-glass fibers has a length of at least 1 mm, and the resulting dental material has a viscosity comparable to that of an amalgam.
