What are Dental Crowns?Dental crowns are restorations that preserve the functionality of damaged teeth, protect cracked or broken down tooth, restore functionality of a tooth with excessive decay, or replace a pre-existing crown.
During the dental crown procedure, the first appointment your dentist prepares or preparation the tooth and makes a molded impression of the teeth to send to a dental laboratory. A fitted, temporary crown is created during this visit to temporarily protect the tooth while the final restoration is being made in the dental laboratory. Once completed, the crown is cemented or adhesively bonded at a second visit
Why might I need crowns?•The tooth has undergone significant decay and there is not enough tooth structure remaining for supporting a filling or an inlay-onlay and maintain functionaility.
•The tooth has large fractured and it cannot be built up using traditional composite bonding techniques.
•After root canal treatment treatment, a post and core and a crown is often needed to strengthen the tooth.
•For cosmetic reasons, to improve the aesthetics of your smile.
|Dental Crown Materials :|
1.Porcelain fused to metal crown
2.All ceramic (all porcelain) crown
3.Metal or gold crown
The material selected is determined by the clinical demands at hand; esthetic demands, strength requirements, material durability and restorative space available.
|Porcelain fused to metal crowns|
Porcelain-fused-to-metal crowns provide for a strong, durable, and esthetic treatment option. One of the key factors for the esthetic and functional success of this type of crown is ensuring the preparation of the underlying tooth structure provides adequate space for the appropriate thickness of metal and porcelain facing.
Porcelain fused to metal dental crowns can be color matched to your adjacent teeth. However, more wearing to the opposing teeth occurs with this crown type compared with metal crowns. The crown's porcelain portion can also chip or break off.
However, the metal underlying the crown's porcelain can show the underlying metal or gold margin at the gum line as gums recede over time. These crowns can be a good choice for the back teeth.
|All ceramic (all porcelain) crowns|
All ceramic or all porcelain crowns are the best natural color match than any other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain fused to metal crowns and they wear down opposing teeth a little more than metal crowns. All-ceramic crowns are a good choice for front teeth.
Today, the predominant material choice for all-ceramic crowns is either zirconia, or aluminous materials. They provide a metal free esthetic option with a number of benefits.
All-ceramic materials continue to evolve in strength and durability, but caution should still be exercised for areas of the mouth requiring heavy function. Continuing research is exploring the significant vulnerabilities of the porcelain systems in such areas.
|Metal or gold crowns|
Metals used in crowns include gold alloy, other alloys (for example, palladium) or a base-metal alloy (for example, nickel or chromium). Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Also, they rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
For gold crowns
Although not as popular a treatment choice for esthetic reasons, gold crowns are still indicated in some reasons. For example, patients with strong bites and those with parafunctional habits such as grinding or clenching might be better served with a gold crowns.
The gold material can provide stronger support to the remaining healthy tooth structure. Gold crowns offer a level of durability that is appropriate for teeth located in the back of teeth, where they will not be highly visible.
Gold crowns tend to offer greater longevity and require less preparation than all ceramic crowns and porcelain fused to metal crowns. When chewing, gold tends to be less abrasive to the opposing tooth than porcelain. This helps to prevent wearing of the teeth.
