Claims5
A unitary instrument for use in making a dental restorative having an understructure and a buildup of porcelain thereon, and for regulating condensation of the porcelain during buildup, said instrument comprising an elongated handle;
- a narrow blade-like member affixed to said handle and protruding therefrom to be manipulated to effect a predetermined buildup of a porcelain paste on a supported understructure;
- and a mallet member affixed to said handle and spaced longitudinally from said blade-like member;
- said mallet member being a mass of substantially cylindrical configuration and having its longitudinal axis the same as the longitudinal axis of said handle and of a radius grater than said handle and being adapted to impart intermittently a tapping force to effect a vibratory action to the supported understructure during buildup of the porcelain paste thereon to induce a rate of condensation of the porcelain paste according to the stage in the buildup procedure;
- said handle being provided with an elongated roughened segment disposed intermediate said blade-like member and said mallet member, said roughened segment being adapted to impart vibrations to the supported understructure interchangeable with said mallet member subsequent to the predetermined buildup of the porcelain paste and upon the segment and the supported understructure being in contact and removable relative to one another longitudinally of the segment.
