ABSTRACT:
A method for marking contact between a dental mounting such as a prepared tooth and a prosthetic device such as a crown, wherein the prosthetic device is to be modified to conform to the mounting. The method comprises applying a clear, mildly adhesive liquid to the surface of the mounting in a thin, uniform film, seating the thoroughly dried surface of the prosthetic device against the mounting to cause protruding areas to abut to one another and to transfer a residue of the liquid adhesive to the protruding areas of the surface of the prosthetic device, and then highlighting the residue on the prosthetic device surface by dusting with a visible powder which clings to the residue, and finally removing the excess powder whereby the areas of undesired protrusion on the surface of the prosthetic device are indicated. Thereafter, the protruding areas of the prosthetic device can be ground away, and the process can be repeated until undesired areas of contact can be eliminated. The method does not damage or modify the surface of the mounting.
