USE OF LIGHT-POLYMERIZING RESTORATIVE MATERIALS IN DIAGNOSTIC CAST MODIFICATION PROCEDURES

During the treatment-planning phase and before provisional restoration s are made for the partially edentulous patient, it is often necessary to complete diagnostic cast modification procedures. Traditionally wa x has been used for this purpose; therefore, it is necessary to duplic ate the modified cast before fabrication of a vacuum-formed matrix. Th e cast duplication procedure can be eliminated by the use of light-pol ymerizing provisional restorative materials for cast modification inst ead of wax. Diagnostic casts for two patients are presented in this ar ticle, where techniques for using such a light-polymerizing material a re described.
