Creating functional finishing lines for RPD's

Wax profiles, for partial framework designing, come in a wide range of shapes and sizes. BEGO recommends using the following profiles to help seal the acrylic junction and stop the acrylic from lifting:
  • Position the relief or preparation wax for the retention areas onto the master model.
  • On the outer edge of the relief wax, place a 0.8 mm round wax profile/bead wire and seal the finishing line towards the relief wax (take care not to deform the rounded edge) - see photo 1. This rounded edge forms a self-sealing internal finishing line in the metal major connector.
  • Complete the wax-up and place either 0.8 mm or 1.35mm round wax profile/bead wire on the top of the major connector to form the external finishing line - see photo 2. It is important not to deform the round contour of the wax profile with a waxing instrument.
The round shape of the profile, of both internal and external finishing lines, help create an undercut for the acrylic to seal into. BEGO hopes this e-tech tip helps improve your future RPD's.

This webinar will cover the important parts of designing lingual bracing arms and why they should be added to most combination cases. Find out what type of milling bur you need - 0¼, 2¼or 4¼ tapered, cross-cut or fine. Furthermore, technicians will realize the importance of a full diagnostic wax up that will help create the blue print.
