ABSTRACT:
The disclosed invention is directed to a method of restoring a tooth with a light cured composite which comprises utilizing a light transparent impression or matrix which constitutes a negative reproduction of the occlusal surface of the tooth. The matrix is made by contacting the tooth surface with a polymeric impression material which when cured is light transparent and flexible. The polymeric impression material is allowed to set and then is stripped away from the tooth surface. A cavity preparation is then made in the tooth surface and treated in the usual manner. A light cured composite is then injected into the cavity preparation. The previously formed matrix is then placed over the light cured composite and pressure applied to the matrix. The composite is then cured by exposure to photopolymerizing light which passes through the transparent matrix. Following light curing, the matrix is stripped away from the tooth surface leaving a restored tooth with the original occlusal anatomy reproduced.
