Porcelain Bridges
Dental bridges are a dental prosthesis which bridges a gap created when a person loses at least one of their teeth.
The bridge is fixed in place by attaching to the adjacent teeth. The part of the dental bridge centered over your missing tooth is called the pontic and the adjacent teeth which it attaches to are called the abutments. The fixed bridge is permanently cemented to the two teeth on either side of the tooth gap. Bridges have the ability to restore a person’s smile, restore a person’s ability speak, and also to optimize the ability to chew. In addition, they can help hold the shape of a person’s face, properly distribute biting force, and help prevent remaining teeth from shifting
The most common type of dental bridge is the traditional
bridge. This prosthetic is held together by dental crowns on either side of the
missing tooth space. This is the strongest and most durable form of dental
bridge and they can be very esthetic. The disadvantage is the adjacent teeth need
to be reduced to make space to place the dental crowns to hold the bridge. If
the two adjacent teeth are in pristine condition then a fixed bridge can be
counter-productive because it can be considered invasive or destructive to
prepare the dental crowns. However, if the adjacent teeth already have dental
crowns or could benefit from dental crowns then a tradition bridge can be an
ideal option.
Another type of dental bridge is the Maryland Bridge. This
is usually used for front teeth since they don’t have as much pressure applied
to them (unlike the back teeth which do most of the chewing). Maryland bridges
are cemented in with resin and often have metal or porcelain wings which attach
to the adjacent teeth on either side of the gapped area. This type of bridge
has the advantage of having less or no preparation (shaving down) of the
adjacent teeth. However, Maryland bridges do not have as much retention as a
crown retained traditional bridge and can be prone to falling off. This can be
frustrating for a patient and if a patient is considering a Maryland bridge
they must be fully informed if there is a possibility it could de-bond. This
type of bridge is great for temporary solutions such as when a patient is
waiting for a tooth socket to heal in preparation for placing an eventual
dental implant.
A Cantilever bridge is another type of bridge which is unique in that it attaches to only one tooth on either side of the tooth gap. This type of bridge only involves crowning one tooth (as opposed to two with a traditional bridge). However, there can be severe deleterious effects of the cantilever bridge on its abutment tooth. This is because when a bridge is only held in on one side then it can place severe torque on the tooth holding it in. This can lead to premature tooth loss if the Cantilever bridge is not used appropriately. One scenario where a Cantilever bridge can be used is in a situation where a very strong dental implant serves as the abutment for the bridge.
