Everything you need to know about the ceramic-metal crown: a long-lasting solution for your teeth
The metal-ceramic crown is one of the most common solutions proposed by dentists to restore damaged teeth. Combining the strength of metal and the aesthetics of ceramic, it offers a durable solution while maintaining a natural appearance. This article explores in detail the advantages, disadvantages, and installation steps of this crown.
What is a metal-ceramic crown?
A metal-ceramic crown is a dental prosthesis used to cover a damaged or weakened tooth. It is composed of two main materials:
- Metal : Forming the internal base of the crown, it provides strength and durability. The metal is often invisible since it is covered in ceramic, but it provides excellent resistance to chewing forces.
- Ceramic : Covering the metal part, it imitates the appearance of natural teeth, with a personalized color to blend in with the patient's other teeth. Ceramic gives the crown an aesthetic appearance, essential for visible teeth.
Advantages of the metal-ceramic crown
1. Resistance
The metal used for the internal structure of the crown ensures solidity in all circumstances. Unlike all-ceramic crowns, metal-ceramic crowns withstand pressure better, making them ideal for molars and premolars that are subjected to significant forces.
2. Aesthetics
Thanks to the ceramic layer, metal-ceramic crowns are almost indistinguishable from natural teeth. This allows for a harmonious smile, while still benefiting from a solid internal structure.
3. Sustainability
These crowns can last between 10 and 15 years, or even more, with proper maintenance. Metal provides great resistance to wear, while ceramic, although more fragile, remains stable over the long term if properly maintained.
4. Versatility
This type of crown can be used for both anterior (front) and posterior (molars and premolars) teeth. For front teeth, aesthetics are paramount, while for back teeth, strength is a major asset.
Disadvantages of the metal-ceramic crown
Despite its many advantages, the metal-ceramic crown has some disadvantages that patients must take into account:
1. Risk of gum recession
Over time, the gums may recede slightly, which can expose the metal edge of the crown. This can result in a slight grayish appearance at the base of the tooth, especially visible on the front teeth.
2. Tooth sensitivity
Some patients may experience increased sensitivity to hot or cold after crown placement, particularly due to the fit of the prosthesis over the natural tooth.
3. Cost
The cost of metal-ceramic crowns can be higher than other dental prosthesis options, due to the complexity of their fabrication and installation. However, their durability and aesthetic appearance often justify the investment.
How is a ceramic-metal crown fitted?
The installation of a ceramic-metal crown is done in several stages and generally requires two appointments with the dentist.
1. Tooth preparation
During the first visit, the dentist prepares the tooth by removing damaged parts and reducing the size of the tooth to make room for the crown. A mold of the tooth is then taken to design the custom crown.
2. Placement of a temporary crown
While waiting for the permanent crown to be made, a temporary resin crown is placed on the tooth to protect it.
3. Making the crown
The crown is made in the laboratory from the mold taken by the dentist. The metal structure is formed first, then covered with several layers of ceramic. Each layer is carefully fired to obtain a smooth and resistant surface.
4. Fitting the crown
During the second visit, the temporary crown is removed and the new crown is tried on. If everything is correct (fit, color, shape), the dentist fixes it in place using dental cement.
How to maintain a ceramic-metal crown?
Caring for a metal-ceramic crown is similar to caring for natural teeth. Here are some tips to help you prolong its lifespan:
- Daily dental hygiene : Brushing your teeth at least twice a day and flossing is essential to prevent plaque buildup around the crown.
- Regular dental visits : Regular checkups will ensure that the crown remains in good condition and that there are no underlying problems with the tooth or gums.
- Avoid Bad Habits : Avoid chewing on hard objects like ice cubes or pens as this can damage the ceramic.
How much does a metal-ceramic crown cost?
The price of a metal-ceramic crown can vary depending on several factors, including:
- Place of installation : Prices vary depending on the region and dental practice.
- The type of metal used : Certain metals, such as palladium or gold, can increase the cost.
- Dentist's experience : An experienced specialist can charge more for his expertise.
In general, the price of a metal-ceramic crown is between €500 and €1200, with partial reimbursement by health insurance and mutual insurance companies. It is advisable to request a precise quote before committing.
The metal-ceramic crown remains an excellent option for patients looking to restore their teeth while combining aesthetics and strength. Although it has some minor drawbacks, its durability and natural appearance make it one of the most popular solutions in dentistry. If you are considering a crown, be sure to talk to your dentist to determine if a metal-ceramic crown is the best solution for you.
