ABSTRACT:
Processes wherein a soft polymer sheet deforms readily under the pressure of dental surfaces brought into contact with one another. As such, the sheet does not itself interfere with such contact. Processes for the sheet include deforming the sheet between contacting dental surfaces, and noting the location and intensity of contact deformations. The position of the sheet is stabilized on the surfaces by temporary adhesion, wherein the adhered sheet does not interfere with contact. Further processes involve deforming the sheet between contacting dental surfaces such that the sheet does not interfere with the contact of the dental surfaces, and utilizing the sheet to support dental materials, such as supporting restorative composite, impression materials, and so on. The sheet is preferably comprised of polytetrafluoroethylene.
