Crown & Bridge

What is a Dental Crown?
A crown is a full coverage restoration that is reserved for badly broken or decayed teeth with very little tooth structure remaining. They are also used to provide base support for in extreme cases of wear or flattened teeth due to grinding.They come in a range of materials which are tailored to certain circumstances. These include - Gold, Porcelain Fused to Metal or Full Porcelain.
Within these categories of crowns, there is a huge variety ranging from high to low translucencies, shades, metal compositions and margin types – these are all selected by your dentist to achieve the perfect colour match and natural opacity as well as the best strength and fit for that individual application. There is no one-size fits all, at least when it’s done well.
Before bonding, all crowns are viewed by you in mouth so you can achieve perfection, if there is any issue it is sent back and remade until it is made perfect.
What is Bridgework?
A bridge is a cemented, non-removable fixture used to replace missing teeth. Now, with the increasing popularity and commonality of implants, the use of bridges to replace teeth is on the decline. However, is some cases, bridges are still viable, conservative and sometimes more beneficial than an implant replacement.
There are 3 types of bridges:
The 3-unit bridge: As the name suggests, there a 3 components to this type of bridge. It consists of a crown-pontic-crown whereby the pontic is a fabricated porcelain tooth connected or “bridged” either side by 2 crowns. This type of bridge is particularly useful when the space you are wanting to replace is adjoined by two teeth either side that are decayed or very heavily filled and may benefit by a crown. Hence, by placing a bridge, you replace the space and strength each side tooth with a crown. If the teeth either side is sound or only have small fillings and will not benefit from a crown, this bridge is not recommended.
The cantilever bridge: Like a 3-unit bridge but with only one crown i.e. crown-pontic. This is a more conservative, cost-effective approach to bridging as only one tooth would need to be crown to support the fabricated porcelain space replacement tooth. The limitation? The pontic must be smaller than the crowned tooth i.e. replacement of a premolar space with the crown on a molar or a lateral incisor (tooth next to front tooth) with a crown on the canine. This is to ensure the support far outweighs the pressure on the fake tooth. Hence the fake tooth is “cantilevered” off the supporting crown.
Maryland Bridge: Probably the most widely and commonly used bridge. It is quite conservative in nature in that it merely uses a “wing” to support the point and not a crown. The wing requires less tooth preparation and hence conserves more tooth structure. Realistically, it is reserved for the replacement of the lateral incisor (tooth next to the front tooth) as it lasts quite well however can be used for the central incisor (front tooth) as well. It is the most commonly used form of bridge due to its conservative nature and affordability when compared to implant replacement.
Before bonding, all bridgework is viewed by you in mouth so you can achieve perfection.
If there is any issues it is sent back and remade until it is made perfect.
