ABSTRACT:
In the formation of a dental restoration unit, a procedure for securely bonding composite resin material to a core structure is employed. A core structure comprising, for example, metal, is wholly or partially covered with a cohesion layer comprised of a blend of lithium, aluminum silicat and fused quartz silicate. The composite resin material is fused to the cohesion. The resulting restoration unit, such as a crown, is less liable to fracture than is porcelain, and can provide a surface which is no more abrasive than is natural tooth enamel.
