Texas State Board Of Dental Examiners Still Require Dental Offices To Follow COVID Emergency Rules And Still Require Everyone To Wear A Mask Regardless Of Governor Ruling

The most common use of flexible partial denture is temporary, or on occasion permanent, replacement of missing teeth. These dentures provide a successful alternative to traditional RPDs.

Flexible RPDs are made of a form of nylon, technically known as super-polyamides. These resins are tough, extremely durable, resistant, and strong. The material is thermoplastic, meaning it will modify shape under high temperature so it can be injection-molded into flexible denture bases to which replacement teeth are attached.

Why Flexible Partial Dentures?

The flexibility of these dentures offers various benefits over the traditional RPD alternatives. Flexible, nylon-based RPDs are more comfortable to wear, can stay securely in place, and look realistic.

Dentures made of flexible polyamides, and they are thin, lightweight, and resistant to fracture. They also provide a good alternative for people who are allergic to acrylic. However, it isn’t easy to repair, rebase, and reline them. And while they have less tendency to stain from teas or coffee than traditional acrylic dentures, they still need to be adequately cleaned and maintained.

Like other partial dentures, flexible RPDs stop remaining natural teeth from moving into the gaps where teeth are missing. They restore aesthetics and function during the transition to more long-term tooth replacements.

It is necessary to remove and thoroughly clean all types of RPDs, as they tend to allow increased bacterial accumulation on the teeth at the gum line.

Caring for your Flexible Partial Denture

Flexible partial dentures stay in place by little projections that fit into the areas between the teeth and gums. This can trap food and bacteria, and hinder cleansing, and the antibacterial action of saliva. Therefore it’s crucial to remove the dentures occasionally to practice regular oral hygiene and clean the appliances. This will help prevent tooth decay and inflammation of the gums.

Avoid overnight wearing of RPDs when salivary flow is reduced, making the mouth dry and the potential for bacterial buildup worse.
