Abstract A temporary protector defined by a sheet of pliable paper or like material of such shape and size as to cover the masticating or occlusal surface of a dental crown. The sheet has first and second sides, with the first side being covered with a film of pressure sensitive adhesive. The film of pressure sensitive adhesive on each protector permits the latter to be removably bonded to the masticating surface of a dental crown prior to the crown being permanently secured to a prepared tooth by the use of conventional means, I.E. a crown and bridge cement, polycarboxylate cement, or the like. Each protector prevents the undulating masticating surface of the dental crown on which it is mounted from being contaminated with cement during the time it is being mounted on the prepared tooth structure. Removal of tiny particles of solidified cement from the surface of a dental crown after it is positioned on a tooth is a tedius, time-consuming operation and one that is completely avoided by use of the protector abovedescribed. The protectors prior to being used are preferably lightly bonded in longitudinal sequence on a first surface of a strip of pliable sheet material such as paper or the like, which strip is wound in the form of a roll and rotatably disposed in the interior of a transversely slotted housing.
In combination with a support that has a surface of substantial area, a plurality of dental crown protectors mounted in spaced relationship on said first surface, each of said crown protectors including: a. A sheet of material of sufficient area and of such shape as to cover the undulating masticating surface of said crown, with said sheet being sufficiently pliable as to conform to the configuration of said surface, and said sheet including a first side; and b. A film of pressure sensitive adhesive that covers the entire surface of said first side, said film serving the dual function of removably securing said crown protector to said first surface until said protector is needed, and said film serving to removably secure said sheet to said masticating surface of said crown to protect said masticating surface from contamination with a bonding agent during the mounting of said crown on a tooth.
