3/4 Gold Bridge

Bridge Retainer

A BRIDGE is a cemented prosthesis that replaces one or two missing teeth.

The supporting teeth (teeth adjacent to the space) are prepared for CROWNS (caps). During this preparation, a small amount of tooth structure is removed from the outside perimeter of the tooth.

The portion of the bridge which restores the supporting teeth to their correct contour are called RETAINERS because they hold the bridge in place. In this photo, the left and right arrows point to the teeth with retainers.

Thus, the term RETAINER refers to the crown components of a BRIDGE that support one or more adjacent false teeth (PONTICS).
