  • Translucent veneering for a dental prosthesis formed by a press to metal process
    Patent number: 10603144
    Abstract: A dental prosthesis, typically formed in a press to metal process, includes application of a porcelain composition sufficient to form a veneer on a dental prosthesis supporting metal structure, the composition having an integrated tooth-like translucency providing an aesthetic appearance. The composition is formed of a dentin frit and an enamel frit, typically sintered into a desired ingot shape including an amount of composition sufficient to veneer the prosthesis. The porcelain composition is a component of a kit that includes opaquers, other porcelains and stains useful in finishing to provide an aesthetic prosthesis.
    Type: Grant
