What is a Ceramic Crown?
Replacing a damaged tooth not only improves the aesthetics of your smile but also its function. If you have a broken tooth, your dentist may suggest a crown. There are a few types of crowns, but a ceramic crown is a dental crown made partially or entirely of ceramic. It is a cap placed over the damaged part of a natural tooth. Ceramic crowns are not only aesthetically pleasing but also provide very durable reconstructions of broken teeth. They are primarily used to rebuild damaged tooth structures, for example, in cases of extensive tooth decay. A crown is also used to strengthen the structure and aesthetics of a tooth after root canal treatment. In cases where a tooth is missing, a crown can be placed on an implant.
Main types of ceramic crowns
Ceramic crowns can be divided into a few basic types:
- ceramic crowns on a metal base
- all-ceramic crowns
- ceramic crowns on a zirconium oxide base
- Ceramic crowns on a metal base
Ceramic crowns with a metal substructure are very common. They consist of metal cores cast from special dental alloys and outer layers of porcelain. These restorations are highly aesthetic, but their particular advantage is their high load-bearing capacity. Another advantage is their lower manufacturing cost compared to other types of crowns. This type of crown is primarily used in cases where significant stresses are generated during biting. These crowns are also used if the tooth receiving the crown is severely damaged.
All-ceramic crowns
All-ceramic crowns are often chosen for their aesthetic appeal, as they are indistinguishable from natural teeth. Although they are not as durable as metal-based ceramic crowns, they still demonstrate a high level of strength and durability. They are characterized by optimal abrasion resistance, similar to that of natural teeth. Their disadvantage is their higher manufacturing cost than metal-based crowns. Furthermore, they cannot be placed on a tooth that is severely damaged.
Ceramic crowns on a zirconium oxide base
These crowns have a core made of an extremely hard material: zirconium oxide. A layer of highly aesthetic ceramic materials is applied to the outside. These crowns are similar in structure to ceramic crowns with a metal base and are also very resistant to high stresses. However, they can be used in people with metal allergies. These crowns are very aesthetic, but unfortunately, their disadvantages are their higher price and longer production time.
Which crown is for me?
The dentist recommends the type of crown appropriate for the patient. The choice is influenced by the bite and health of the tooth to which the crown is to be placed. The patient's financial resources and the time available for treatment also play a role.
In conclusion
A ceramic crown is a very durable prosthetic restoration, similar in durability to natural teeth. It can remain in perfect condition even after 15 or 20 years. It is important to keep up good personal hygiene for the longevity and health of your crown.
