ABSTRACT:
Shielded dental contact marker has a thin, supple support layer which carries thereon a thin marker layer, such as carbon. A thin, hard protective shield layer of wax overlies the carbon layer. The shield layer is of such thickness and appropriate density as to compensate for periodontal ligament compression so that only forceful dental contact will penetrate the protective shield layer and only those points of forceful contact pressure between teeth are marked. The wax layer is sufficiently thin and hard that lateral shield layer flow does not smear or distort the mark on the dental surface.
