Use of transparent vinyl polysiloxane in a minimally invasive approach for creating composite resin undercuts for partial removable dental prostheses.
A technique using a transparent vinyl polysiloxane material developed for use with light-polymerized composite resin and that does not require a lubricant is presented for creating composite resin undercuts for partial removable dental prosthesis clasps. With a surveyor, the undercut is waxed on the diagnostic cast according to the intended path of insertion. The transparent vinyl polysiloxane is used to fabricate a template for the undercut. The template is used intraorally to create the undercut in composite resin on the abutment tooth.
