How do Bridges function?

A bridge will be recommended to the patient when there is more than one missing tooth. Gap caused by the missing tooth leads to the rotation and shift of the remaining teeth into the vacant spaces, which will result in a bad bite. The imbalance in the contour caused by the missing teeth can result in gum disease as well as disorders like Temporomandibular Joint (TMJ).

Bridges are generally used for replacing one or more than one missing tooth. The bridges successfully span the spaces wherever the teeth are missing. They are cemented to the implants or the natural teeth that surrounds the vacant spaces. These teeth are known as abutments which serve as an anchor for the bridges. Pontic, which is a replacement tooth, is attached to crowns that coat the abutments.

Conventional Fixed Bridgework

Fixed bridgework involves preparation of the teeth on each side of the gap so that crowns (caps) can be placed. The crowns are joined or bridged together by the replacement porcelain tooth forming a rigid bridge, which is cemented onto the anchoring teeth. It is often the treatment of first choice when the adjacent teeth are worn, eroded, disfigured or heavily filled.

Bonded Maryland Bridgework

Bonded Maryland bridgework is fixed to the back of the tooth adjacent to the gap via a bonded “wing”. Treatment involves minimal preparation to the back of the tooth. Bonded bridgework is appropriate when the tooth adjacent to the gap is intact and there is plenty of tooth enamel to reliable bond onto. It is most commonly used to replace missing upper lateral incisors. An alternative treatment would be an implant. How are Crowns and Bridges structured?

Prior to the formation of either Crown or Bridge, the tooth or the teeth have to be abridged in size so that the bridge or the crown is able to cover it properly similar to a thimble that perfectly fits over a peg. After decreasing the size of the teeth or tooth, the dentist will record the impression to offer an identical mold for the bridge or crown. If porcelain has to be used then the dentist will conclude the right shade for the bridge or crown so that it matches the natural color of your teeth.

Through using the impression, the dental lab will be able to build the crown or bridge, exactly in the material that the dentist requests. A temporary bridge or crown will be placed in the mouth while the permanent ones are under preparation. As soon as the permanent crown and bridge gets made, the temporary ones will be removed and the new ones will be cemented over the primed teeth.
