Ceramic crowns and bridges
Ceramic crowns, porcelain teeth, porcelain covers are the most common fixed prosthetic solution in case of tooth damage or multiple extensive aesthetic fillings. The crown protects the tooth from further damage and prevents its further deterioration, the appearance and color of the tooth is improved for a natural smile and self-confidence.
Description of the procedure
A ceramic or porcelain crown (cover) is a ‘cap’, i.e. a prosthetic replacement that is the ideal solution in situations where your natural tooth is so damaged that the filling cannot completely replace the lost part.
Crowns are recommended in order to restore the functionality of the tooth in case of significant decay due to large caries and in endodontically treated teeth……..
TYPES OF DENTAL CROWNS
- Metal-ceramic crowns
The base of the crown is made of a metal alloy that is completely covered with ceramic so that the metal part is not visible. The metals used to make metal-ceramic crowns are gold alloys, alloys of other metals. The main advantage of metal-ceramic crowns is that the metal in the base provides exceptional strength, but also elasticity. For clients who are allergic to other metals, we recommend white gold, which is a biocompatible precious material, or zircon.
- Glass-ceramic crowns
Glass-ceramic crowns meet the high aesthetic demands of clients. Ceramics completely mimic the optical properties of natural teeth, such as translucency, transparency and luminescence, which results in a crown that cannot be distinguished from a natural tooth. Also, since it does not contain metal, there is no discoloration of the gum edge or metal seeping through the tooth. Glass-ceramic crowns are suggested for front teeth to maintain superior aesthetics.
extensive damage after therapy, which is why it is necessary to primarily protect the tooth and strengthen it with an extension.
Ceramic is characterized by high strength, withstands high temperature changes, is resistant to chemical influences, is biocompatible and mimics a natural tooth.
How is a ceramic crown placed?
Before placing on the natural teeth, it is necessary to prepare the tooth to the thickness of the material used to create a place for the crown.
Then impressions of the teeth and surrounding tissues are taken, which are sent to the prosthetics laboratory for fabrication. After the trial of the metal structure or zircon, the marginal occlusion of the color and the contacts are also tested, after which the ceramic crown is cemented to the tooth. The ceramic crown completely covers the crown of the tooth, that is, the visible part of the tooth that is in the mouth.
The crown is also installed on dental implants to completely replace the lost tooth and avoid the grinding of adjacent teeth. Permanent crowns can be made of metal-ceramic, glass-ceramic and zircon-ceramic.
- Zircon-ceramic crowns
Zircon is a high-quality material used to make crowns and bridges. Zircon-ceramic crowns and bridges are characterized by biocompatibility and precision, while at the same time the natural aesthetics of the teeth are preserved. Because zircon-ceramic crowns are made very precisely, gum irritation is also reduced. The advantage of these crowns is the impossibility of the appearance of the so-called “black edge” due to receding gums because there is no metal in the construction.
A complete clinical examination of the teeth and gums, using X-rays and a clinical examination determines the current state of oral health, the state of the tooth roots and the surrounding bone, after which a therapy plan is drawn up.
The course of the intervention
If a large part of the tooth is missing, it is necessary to first strengthen the tooth with a post and core build up so that the crown can be placed. After molding, an impression of the teeth is taken, on the basis of which a suitable crown is made in the laboratory, making sure that the color matches the surrounding teeth in the mouth.
