What Are Flexible Partial Dentures?

For people who are missing a few teeth, false teeth 'bridged' to adjacent teeth are a long standing remedy. These bridges can be fixed in place or removable.

Two types of removable bridges

There are two types of removable bridges, those on metal frames and those on flexible plastic frames. Metal frame bridges are stabilized by attaching them with metal clasps to adjacent teeth.

Stabilizing plastic flexible bridges can be challenging if several teeth are to be replaced.

Bone shrinkage and bridges

The downside of all partial bridges is that they do not stimulate the supporting jaw bone, resulting in bone shrinkage. Over time, bone shrinkage results in a gap between the false teeth and the gum line.

The not so flexible, plastic flexible bridge

With metal frame bridges, the gaps can be closed by relining the base of the appliance. With metal frame bridges, additional teeth may also be added to the bridge.

Plastic flexible bridges cannot be modified when bone shrinks or additional teeth need to be added. A new appliance must be made. 

Flexible bridges have their place

Flexible bridges are light and may be more comfortable for many patients who have chosen them. They are often a good short term solution.
