Abstract:
1. A method of making a multi-layered dental device, comprising the steps of: shaping a first wax-like polymerizable dental material, said first material being dimensionally stable in its uncured state at ambient temperature and comprising a mixture of monomer, oligomer, and light sensitizer and optionally including reinforcing filler, to form a first portion of a polymerizable dental device, shaping a second wax-like polymerizable dental material, said second material being dimensionally stable in its uncured state at ambient temperature and comprising a mixture of monomer, oligomer, and light sensitizer and optionally including reinforcing filler, to form a second portion of said polymerizable dental device, and polymerizing said first and second dental materials by light-curing after both materials have been applied to form a multi-layered dental device having a polymeric matrix, which alone, has a flexural modulus of at least 250,000 psi and a flexural strength of at least 5,000 psi.
