ABSTRACT:
A method for forming a layered dental restoration in which there is a continuous polymeric resin phase but in which the reinforcing filler compositions of the respective layers are different. A sub-layer, composed of a polymeric resin binder having a refractive index within the range of about 1.53 to 1.56, in admixture with suitable catalysts and a finely-divided reinforcing inorganic filler having a refractive index substantially different than that of such resin, is first applied to the site of restoration and, before the sub-layer has fully cured, a surface layer composed of the same resin and catalysts but a different inorganic filler is applied to the site over the sub-layer. The filler of the surface layer consists essentially of a finely-divided inorganic material having substantially the same refractive index as that of the resin common to both layers.
