A dental crown is a tooth-shaped "cap" that is placed over a tooth to cover the tooth to restore its shape and size, strength, and improve its appearance. A dental crown, when cemented into place, fully covers the entire visible portion of a tooth. A dental bridge is used to replace one or more missing teeth. A bridge is made up of two or more crowns for the teeth on either side of the area of the missing tooth/teeth. These two teeth act as anchoring teeth and a false tooth/teeth in are in between bridging the teeth together.
After restoring the lost portion of the tooth, the tooth is trimmed from all sides usually under local anesthesia. This trimming is done to ensure proper space for the crown to be fitted.
A mould or impression follows the trimming and this mould is sent to the laboratory where skilled technicians fabricate a crown. After receiving the fabricated crown, it is inserted on the prepared tooth with a dental cement.
Yes. The dentist's main goal is to create crowns that look like natural teeth. That is why dentists take an impression. To achieve a certain look, a number of factors are considered, such as the color, bite, shape, and length of your natural teeth. Any one of these factors alone can affect your appearance. If you have a certain cosmetic look in mind for your crown, discuss it with your dentist at your initial visit. When the procedure is complete, your teeth will not only be stronger, but they may be more attractive.
With a bridge, it is more important than ever to brush, floss and see the dentist regularly. If buildup of food debris and plaque -the sticky film of bacteria formed from food acids-is not controlled, the teeth and gums can become infected, requiring further treatment and resulting in possible loss of the bridge. We recommend using floss threaders that help remove bacteria from hard to reach spaces between the bridge and adjacent teeth and gums. Crowns on the bridge cover most of the exposed portion of your tooth and decay does not affect a bridge since it is made of metal and /or porcelain. However, where the natural tooth meets the crown of the bridge can become decayed. If optimal oral hygiene care is maintained, a bridge can last for many years.
For a traditional fixed bridge, the first appointment consists of the dentist reducing the adjacent abutment teeth that will act as anchors. Impressions are made, from which a metal framework, including the pontic, is created. By the second appointment, the final bridge is fitted over the teeth. The total treatment time is usually around one week, depending on the type of bridge. However, because it is often difficult to match the natural shade of your teeth, the treatment time may be longer.
Since a long time, porcelain fused to metal (PFM) crowns and bridges have provided good functional and esthetic support. But In some situations, where esthetics is a major concern, like in replacing anterior teeth, PFM crowns are not the best choice. The black metal collar around the crown may look unaesthetic. Metal free crowns and Metal free crowns are of many types. Castable ceramic crowns like IPS Empress, Lava, Alumina and Zirconia based crowns like Procera and Cercon are the choices available. IPS Empress and Empress Lava are used for single anterior tooth replacement and provide excellent esthetics.
Cercon and Procera on the other hand may be used not only for single crowns but also for multiple unit bridges. Besides providing excellent esthetics, these materials provide good strength for long span bridges.
