ABSTRACT:
Disclosed is a dental appliance system having use as an orthodontic retainer, bridge, space maintainer, splint and the like, the improvement wherein a structural component thereof is formed from an effective fiber-reinforced composite material comprising a polymeric matrix and a reinforcing fiber component embedded within the matrix, the reinforcing fiber component comprising at least 20% by weight of the composite material and being substantially fully wetted by the polymer matrix, the composite material being substantially free of voids and having a modulus of elasticity greater than 0.5 x 10.sup.6 psi.
