What materials can crowns be made from?
There are 3 main categories of crowns;
- All Metal Crowns - A variety of materials can be used for all metal crowns, from non precious alloys to high gold content crowns. The main advantage of such crowns are that the
require less preparation (drilling) of the tooth, however the main disadvantage is their poor cosmetics.
- Porcelain fused to Metal Crowns - These tooth coloured crowns offer a more natural appearance than metal crowns and contist of a metal core covered with a porcelain layer. The
main advantage is their greater aesthetic results, however in cases areas of metal can be visible from certain angles
- All Cermaic Crowns eMax - Modern advances in ceramic technology have paved the way for highly cosmetic and durable all ceramic crowns. These crowns are 100% metal free, thus
offer the highest cosmetic appearance. Unlike metal ceramic crowns, there is no risk of black lines appearing around the gum which can occur following recession, and their metal free structure allows
light to transmit though the crown like a natural tooth. http://www.ivoclarvivadent.us/smiletothemax/
Fitting a crown takes two visits with your dentist. At the first visit your dentist will prepare the tooth and will fit a provisional crown to protect your tooth until your next
appointment. The laboratory will make a crown
specifically for you which will be fitted at your second visit. Once you are happy with the crown and how it looks, it will be cemented firmly into place.
