What Are Removable Partial Dentures?

Removable partial dentures (or RPDs) comprise replacement teeth affixed to a pink or gum-colored plastic foundation, occasionally held in the mouth by a metal framework. They may be a good alternative to permanent bridgework or implants when replacing lost teeth. Full dentures replace all teeth in a jaw, while removable partial dentures replace one or more teeth. RPDs, unlike fixed bridgework, may be removed from the mouth by the patient if needed.

Types of removable partial dentures

RPDs are often utilized in one of two scenarios. During the transition to more long-term and permanent tooth replacements, as a temporary option to restore function and aesthetics. Or, when patients cannot afford dental implants or fixed bridgework, this is a permanent option to restore lost teeth. RPDs are often less costly than dental implants or fixed bridgework in most cases.

Rests, clasps, or precise attachments are used to secure removable partial dentures to the remaining teeth. They are supported by the gum ridge regions where the teeth used to be and the palate (or roof of the mouth) in the case of an upper RPD. The different types include:

The "flipper"

This kind of RPD is constructed of acrylic plastic resin and is often used as a temporary denture. Flippers attach to the necks of existing teeth using metal wire clasps to help with retention and stability. This kind of RPD is less comfortable, has a looser fit, and is more prone to wear and stains. Furthermore, the metal clasps that hold the appliances in place may be unattractive when visible toward the front of the mouth.

Partially flexible dentures

Flexible RPDs are constructed of flexible polyamide, a kind of nylon. The material is thermoplastic, which means it will change form when exposed to high heat, allowing it to be injected into flexible denture bases, where new teeth will be affixed later.

Flexible partial dentures usually appear more natural, remain in position, and are easier to wear. They feature thin, gum-colored extensions that click onto the crowns of neighboring teeth along the gum line instead of metal clasps, offering a significant aesthetic enhancement.

Partial dentures with precision attachments

This kind of partial denture is manufactured with accuracy and is typically composed of a light and robust metal alloy, allowing the partial denture to be extremely thin and inconspicuous. The prosthetic teeth are connected to the metal substructure and are supported by pink resins or polymers that resemble gingival tissue.

Precision attachments are used to secure the removable partial denture to the natural teeth. These attachments are more aesthetically pleasing than clasps and provide greater stability. Crowns or bridges on natural teeth are typically required with attachments to enhance the partial denture fit.

The fabrication of removable partial dentures may take several weeks and multiple dental office appointments.
