FIXED AND REMOVABLE BRIDGES

Bridge is a device used to replace missing teeth attaches artificial teeth to adjacent natural teeth, called abutment teeth. Bridges are either permanently attached “fixed bridges”, or they can be removable.

Teeth may be lost due to a variety of reasons.  These include advanced periodontal disease, trauma or decay. If missing teeth are not replaced, your other teeth can drift out of position. The area also becomes more susceptible to gum disease and decay of the surrounding teeth.

A bridge is a restorative structure used to replace missing teeth.  Bridges consist of one or more false teeth that are held in place by fixtures that attach to the surrounding teeth. Bridges fall under two main categories, fixed and removable partial dentures.  Fixed bridges are cemented in place and cannot be taken out.  Removable partial dentures are not permanently attached and are removed at night or for cleaning purposes.

Bridges can dramatically improve the appearance of your teeth by replacing missing teeth, or teeth that have to be extracted.  The materials used to create the bridge are made to match the color of your natural teeth, while providing comparable structural support.

Fixed Bridge

Traditional Fixed Bridge
A traditional fixed bridge is composed of a full artificial tooth with crowns attached to either side.  These crowns are cemented over the teeth next to the missing tooth, and hold the artificial tooth in place where your missing tooth had been.  Bridges are custom designed to look just like natural teeth and to fit with your bite.

Resin-Bonded Bridge
In some cases, fixed bridges may be anchored using resin and metal bands instead of crowns.  This may be appropriate when the abutment teeth are healthy, well anchored and free of fillings.  In this case, metal anchors are affixed to the abutment teeth using a strong resin.  The artificial tooth is then anchored to these bands.

Procedure for Fixed Bridge

The teeth next to the empty space will be reduced in order to receive the crown portion of the bridge.  Then an impression will be taken of the whole area.

This impression is sent to a lab, and a bridge custom-designed to fit the area.  Just as with the placement of a crown, a temporary bridge will be put in place to protect your teeth and gums while the restoration is being constructed.

What materials are used?

Bridges can be constructed from gold alloys, non-precious alloys, porcelain, or a combination of these materials. Porcelain is often bonded to either precious or non-precious metal.

How do I take care of my bridge?

A strict regimen of brushing and flossing will keep the bridge and surrounding teeth clean. This is of critical importance as the bridge relies on the neighboring teeth for support.
