The Flexible Framework

The Flexible Framework RPD’s ?

The most recent advance in dental materials has been the application of Nylon-like materials to the fabrication of dental appliances. Nylon generally replaces the metal, and the pink acrylic denture material used to build the framework for standard removable partial dentures. Its nearly unbreakable, is colored pink like the gums, can be built quite thin, and can form not only the denture base, but the clasps as well. Since the clasps are built to curl around the necks of the teeth they are practically indistinguishable from the gums that normally surround the teeth.

A second type of flexible partial denture base uses a Vinyl Composite instead of nylon.The most commonly sold brand is Flexite. A second brand is Ultraflex: These materials are also flexible and can be built with tooth or gum colored clasps.

Unlike nylon partials, they are much easier for the dentist to adjust making them more “user friendly” denture base. Even though this type of denture doesn’t rest on natural teeth like the metal framework variety, the clasps rest on the gums surrounding the natural teeth. This tissue, unlike the gums over extraction sites, is stable and changes very little over time which keeps these RPD’s stable and unchanging similar to the cast metal variety This type of partial denture is extremely stable and retentive , and the elasticity of the flexible plastic clasps keeps them that way indefinitely.
