What are teeth crowns?
A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
Although there are several types of crowns, porcelain (tooth colored crown) are the most popular. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced. Porcelain crowns are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.
Why teeth crowns are necessary?
Crowns are made on the teeth to compensate for lost hard dental tissues. As a bridge support when restoring teeth. For aesthetic reasons it is necessary to change the shape, position or color of natural teeth.
Teeth crowns are also used for the next problems
- cracked or cracked tooth
- tooth damage that cannot be filled
- caries weakened tooth
- unsatisfactory shape or color of teeth
Types of teeth crowns
- Metal-ceramic crownsMetal-ceramic crowns or covers consist of a base made of metal and ceramic applied over a metal base. Because of their strength and ability to withstand high chewing pressure, metal-ceramic crowns are a better solution for back tooth replacement.Since the metal base does not transmit light, this type of coating cannot completely imitate the natural color of the teeth. The metal base sometimes makes the teeth have a matte color, unlike the translucency of natural teeth. This is especially pronounced if the adjacent teeth are natural and in the observer’s field of vision.
- Porcelain CrownsPorcelain crowns almost entirely take on the optical properties of natural teeth. You will often have trouble recognizing which tooth is natural and which is artificial. They are the pinnacle of today’s dentistry.The ability of porcelain to transmit light just as much as a natural tooth allows a metal-free crown or cover to achieve a natural color and appearance.These porcelain crowns are less flexible than metal-ceramic crowns and due to their rigidity are not the most suitable solution for posterior teeth.
Teeth crowns making and installation
For the making of the porcelain teeth crowns is used newest CAD CAM technology. Metal-ceramic crowns are older design of crowns meaning they use older technology.
If there are not enough teeth for the crown, dentists will endodontically treat the tooth and make a tooth augmentation (“pin”) to compensate for the lost structure. Then they will grind the tooth and shape it into required, often conical shape. The fingerprint is taken and sent to the laboratory.
Until the next time, the patient wears temporary crowns that protect the bat from mechanical and thermal stimulation. The crown is then made in the laboratory based on the prints. After that, the crown is permanently cemented in the mouth by classical or adhesive techniques.
