Ready-to-use preshaped, prefabricated cured structural components are prepared in a variety of shapes and sizes to be used in the fabrication of dental appliances. Preferably the structural components are fabricated of a fiber-reinforced composite material or a particulate-filled composite material comprising fibers or particulate filler impregnated with a polymeric matrix. The polymeric matrix is partially or fully cured to the point of sufficient hardness to provide a ready-to-use structural component for use in the fabrication of dental appliances such as orthodontic retainers, bridges, space maintainers, tooth replacement appliances, splints, crowns, partial crowns, dentures, posts, teeth, jackets, inlays, onlays, facings, veneers, facets, implants, abutments, cylinders, and connectors.

1. A material for use in the fabrication of a dental appliance system comprising:a prefabricated preshaped block comprising particulate-filled composite material throughout the entire block wherein the particulate-filled composite material comprises a polymeric matrix and a particulate component wherein the block is shaped and cured to a hardness for use in the dental appliance system; wherein the particulate component consists essentially of an inorganic filler having an average particle size diameter of about 0.5 to about 5 microns and wherein the particulate component is present in an amount from about 65% to about 85% by weight of the block; and wherein the block is designed for use in a CADCAM system.
