LEARNING OUTCOMES
Upon completion of the course, students will:
- know the principles of partial denture design and fabrication using a cast metal framework.
- know how to use the survey for a proper study and design of various partial dentures.
- know how to use the various appliances required for the completion of a partial denture with a cast framework.
- know, in theory and in practice, the fabrication steps of a partial denture.
- know how to select and use modern materials and fabrication techniques.
SYLLABUS
The course includes a series of theoretical and laboratory classes, so that students make application of what they learn in theory.
Theory
- Elements of anatomy and physiology of the stomatognathic system related to application of partial dentures.
- Engineering principles of partial denture design.
- Principles of partial denture design. Use of a surveyor. Greatest circumference. Path of insertion.
- Case studies.
- Kennedy’s classification.
- Support, retention, stability. Rotation axes. Major, minor connectors, bars.
- Types of clasps, rests.
- Alloys. Properties, selection. Refractory Investments, properties, selection.
- Casting procedure. Metal framework processing.
- Tooth selection. Set up. Resins.
- Repair methods of both the metal part and the acrylic part of a partial denture (saddles – artificial teeth).
- Case studies
- Digital Removable Partial Denture fabrication workflow.
Lab
- Fabrication of a custom tray.
- Fabrication of a master cast.
- Study and design of a partial denture.
- Elimination of undercuts, copy of the master cast in investment form. Fabrication of a wax pattern, casting, processing, finishing and polishing of the metal framework.
- Wax rims, mounting on the articulator, artificial tooth set up, flasking, polymerization, finishing and polishing of the plastic parts.
