One Visit Crowns
This is one of the greatest advances in dentistry. Over twenty years ago early attempts at using computers to aid the production of crowns was made. These were slow, laborious to make and not particularly well fitting. With advances in computer technology, increasing speed and accuracy, and sophisticated software improving the level of support for dentists in the design process, the crowns and inlays produced can be more accurate, stronger, and visually comparable to the best traditional laboratory-produced crowns. The more advanced laboratories are now using this technology to produce crowns and bridges.
The main advantages of the technology are:
- Treatment and fitting appointment are combined in one visit this means you save time and travel and where it is necessary a single injection covers both procedures.
- You avoid the necessity to have moulds taken, which can be a problem for some. Instead a camera is used to take images.
- You don't need to wear a temporary crown, which may break, or fall off with the inconvenience of a recementing visit and possible embarrasment if it's in you smile line.
- The fit is extremely accurate which means it is stronger as it bonds to the shape of the remaining tooth making it less likely to break and leaking around the edges with the possibility of decay occurring under the crown is reduced when compared with traditional crowns.
- The durability of the crowns is comparable to gold, which means replacement should be rare.
- The crowns are free of metal and look more natural, improving overall appearance when compared with traditional fillings and metal reinforced crowns.
- The crowns are of similar hardness to normal tooth which means you are less likely to wear opposing natural teeth than the traditional much harder metal or metal reinforced porcelain crowns.
- Because the fit is so accurate, we may be able to fit crowns to very small stumps of teeth, which may save the cost of having them root filled and a post to provide the support required by a traditional crown. This could save you several hundred pounds in treatment costs and several visits.
- The technology allows one visit makeovers, where we fit crowns or veneers to several teeth during the course of a morning.
With so many advantages and no disadvantages the only barrier to all dentists providing this treatment is the cost of providing this equipment, which is around £70,000 for the complete kit.
The stages involved
As with a normal crown you usually need to be numbed for the tooth to be prepared.
Whilst it is being prepared several images are takenand loaded into the computer.
After the preparation phase you are able to sit and have a coffee or tea whilst reading magazines, for example, for about half an hour whilst the crown is being made.
You return to the surgery to have your new crown fitted.
You can use it normally once any numbing has worn off.
Simple, efficient, convenient.
