It is responsible for managing the Repository components (RPD components) for report generation. She is 10 years post treatment and doing well. The residents reported that the digital RPD teaching approach enriched their knowledge and deepened their understanding of RPD design. The major and minor connectors were made of Ce-TZP/A and the retention clasp was made of PEEK instead of Co–Co alloy, which is generally used for the conventional RPD frameworks. INDIRECT RETAINER- The component of rpd which assists the direct retainer in preventing displacement of distal extension base by acting through lever action on the opposite side of the fulcrum line when the denture moves away in pure rotation around the fulcrum line. © 2020 Foundation for Oral-facial Rehabilitation. This program reviews some of the basic principles of RPDs and outlines the reasons why patients often select RPD treatment as opposed implant therapy when cost factors and anatomic limitations and other factors are taken into consideration. The four basic components involved in an RPD are the artificial teeth, the denture base, retainers, and connectors (Figure 3.17). Courtesy Dr. A. Davodi Courtesy Dr. T.

Removable partial dentures (RPD) will continue to be one of the primary methods used to restore missing dentition for the foreseeable future.

An RPD framework includes five components: The major connector, minor connectors, rests, direct retainers, and indirect retainers (in distal extension RPDs). Second, none of the RPD components was made of metallic materials. 5 0 obj Antero posterior double palatal bar.
