These are structures designed to replace one or more lost dental pieces. The missing tooth piece is replaced by an artificial crown secured by crowns cemented to other close by pieces.
The bridge is a structure cemented to the close by pillar pieces therefore impossible to be removed by the patient. In order to make a bridge the pillar piece has to have bone support, no periodontal problems and long roots. The bridge stabilizes the bite, improves aesthetic factors in form, size and color, providing an excellent appearance to your smile.
The pieces that support the bridge require some dental attrition or occlusal wear to house the crowns.
