Can Zirconia Crowns Crack?
Due to their ease of manufacture, their great durability and superior aesthetics, dental crowns are the most used type of prosthetic work in dentistry. The indication for the use of crowns are diverse. But the main one is when there is a great destruction of the tooth, making it hard to save the whole tooth, and instead, the dentist will prepare any existing tooth and fit a crown over it that matches the look and feel of a natural tooth. The dental prosthetic crown is the treatment of choice to rehabilitate the tooth compromised by caries or large fractures. In addition, it is possible to obtain an aesthetic similar to natural teeth. In the vast majority of cases, dentists use ceramics to recreate the anatomy of the tooth, which results in a natural look. This type of prosthesis provides a fixed and versatile tooth and can be performed directly on broken teeth and also on dental implants.
What is a dental crown?
The dental crown is a type of prosthesis where your dentist will “cover” the tooth completely with a prosthetic tooth. The existing tooth will be prepared to serve as a base for the future crown or prosthesis. This treatment has the function of rehabilitating the tooth, restoring its aesthetics and function. It is extremely used in dentistry and can be made with different types of materials.
Types of dental crowns
There are different types of dental crowns, below are the most common:
1) Full metal dental crown
Little used nowadays due to the unfavorable aesthetic factor. It still has some indications, especially when the space between teeth is small. Within this subtype of treatment, we have the crown in gold. Some still arrive with the intention of using this type of prosthesis, however the price may make it unfeasible.
2) Metal-ceramic dental crown
It is the most used type of dental crown. It has a metal infrastructure and ceramics are applied on top. This treatment provides excellent support and good aesthetics, especially in posterior teeth.
3.) Non-metal all zirconia crown
Its use has increased a lot in recent years due to increased resistance. This type of crown provides excellent aesthetics, especially in anterior teeth. The zirconia crown, which is white instead of the dark color of the metal, provides long-lasting and strong rehabilitation for your smile. Zirconia resists cracking, which makes it a good choice for people who grind their teeth (bruxism). Pure zirconia does have its aesthetic limitations, and for this reason, the most common choice for crowns is zirconia and porcelain crowns.
4.) Porcelain Zirconia Crowns
This is a type of crown where the inner structure that touches the existing tooth is made from zirconia, which helps keep it strong and aesthetically pleasing.
5.) All Porcelain Crown
Made with the same materials used in the aesthetic transformation of the smile with porcelain veneers and dental contact lenses, the dental prosthesis in pure porcelain brings more natural colors. Versatile, it can be used from techniques such as pure porcelain crowns or dental prostheses on implants.
