If the patient suffers from bruxism (teeth grinding), in which the chewing muscles spontaneously contract during sleep, then the installation of ceramic crowns is contraindicated. Also, they cannot be placed with non-standardly low natural teeth and deep bite.
Types of ceramic crowns
For the manufacture of metal-free dentures, such types of ceramics as porcelain masses and, developed with the help of high technologies, aluminum dioxide and zirconium are used.

Advantages of ceramic crowns
- Ceramic constructions, having high external data, are ideal for front teeth. This effect is achieved by the absence of a metal frame, so the light naturally penetrates through the ceramics, providing an impeccable appearance of the teeth and maximum similarity to natural ones.
- Layering ceramics increases the depth and natural light absorption of the crown, and it looks decent and natural next to healthy teeth.
- Due to the absence of metal, this type of crown preserves the natural appearance of the gums: it does not darken or become inflamed. Also, dentures do not darken from time, tea, coffee, tobacco, food dyes.
- The density of fit to the gum protects against the possibility of developing caries. The properties of ceramics allow it to protect the oral cavity from allergies. Full compatibility with the body creates comfort, does not cause discomfort, irritation of the mucous membrane and foreign taste in the mouth.
- The production of metal-free crowns using various successful digital technologies has made it possible to significantly increase the strength of the products themselves and the quality of the installation. One of the many advantages is also the preservation of the pulp (vessels and nerves), which keeps the tooth alive under the crown.
- A ceramic prosthesis is relatively light, its manufacture has practically no errors and does not take much time, and the process of installing crowns does not cause complications.
Disadvantages of ceramic crowns
- In the most modern ceramic crowns, the number of flaws is minimized, but standard types are inferior to their counterparts in strength. In this regard, most types of such prostheses are recommended to be placed mainly on the front teeth, then the crowns will live approximately 10 years.
- The complexity of manufacturing is reflected in the cost. However, this can hardly be called a disadvantage: good professional work really should be evaluated accordingly. If the structure breaks down, repairs of high complexity will be necessary, which is not surprising.
