What are Metal-Ceramic Crowns?
Crowns are caps for teeth that cover the entire surface of a tooth, while multiple connected crowns are called bridges. The main difference between crowns and bridges is that a crown is placed on a tooth that is already in the mouth. On the other hand, connected crowns, or bridges, can replace a missing tooth (i.e., bridge the gap).
At the dental office of Dr. Bede, crowns and bridges are made from various materials, with a combination of metal and ceramic being one of them. This type of material involves a metal base on which ceramic is placed, making it match the desired color, shape, and size of the tooth.
When are Metal-Ceramic Crowns Installed?
We create crowns in cases where a tooth is extensively damaged and mostly composed of fillings. It is better to protect such a tooth with a cap to extend its lifespan. This is also recommended for teeth with removed nerves, as they are more prone to breaking.
The aesthetics of teeth is another reason for creating ceramic teeth, to which we pay special attention. When a patient is dissatisfied with the appearance of their teeth, their position, shape, or color, we can use crowns to correct their aesthetic appearance.
When is the Installation of Metal-Ceramic Bridges Recommended?
Dental bridges are made when one or more teeth are missing, but it is necessary to have healthy natural teeth in front and behind the empty space. These teeth then serve as supports for the bridge, which will carry the structure of several connected crowns.
Besides cases where teeth are missing, bridges can also be made when all teeth are present but are weakened for some reason (e.g., periodontitis, fractures). By connecting several such teeth into one structure, they can better withstand chewing forces and perform their function more effectively.
Procedure for Installing Metal-Ceramic Crowns
The process of installing metal-ceramic crowns and bridges is the same and is considered routine. After examining the teeth, checking their health, and analyzing an X-ray, we proceed with tooth preparation.
Tooth Preparation
Tooth preparation involves reducing the size of the tooth to the thickness of the future crown. This is done under anesthesia and is completely painless.
Taking Impressions
After tooth preparation, impressions are taken for the crown. It is necessary to take impressions of all teeth, both upper and lower so that the future ceramic teeth fit well with the patient’s bite. The impressions are then sent to the dental laboratory, where technicians start making the crowns or bridges.
Installation
During the process, several trials are necessary to analyze the function and appearance of the new teeth. Once the dentist and the patient agree that the teeth meet all desired requirements, the crown is cemented, i.e., permanently glued to the tooth. This process can be done under anesthesia if necessary. After cementing, the process is complete.
Advantages of Metal-Ceramic Crowns
Teeth with large fillings or reconstructions will have a longer lifespan if protected with a crown. Additionally, this type of cap can significantly improve the appearance of teeth and the overall smile of the patient.
Disadvantages of Metal-Ceramic Crowns
The main disadvantage of metal-ceramic crowns and bridges is tooth preparation. However, this belief is mostly unfounded because the teeth being prepared usually already have fillings or removed nerves, so this type of cap can only help.
Installation of Metal-Ceramic Crowns and Bridges at the Clinic
The procedure for making and installing crowns and bridges depends on the number of teeth being made and can take 7-10 days. During the process, temporary crowns can be made so that the patient does not have to endure prepared teeth. These are made from a special type of plastic and, besides having an aesthetic function, also protect the prepared teeth from hot and cold stimuli.

Frequently Asked Questions
How long does it take to feel better after installation?
It will take a few days to get used to the new bite and maintain the crowns or bridges in a functional sense.
Why is it important to replace missing teeth?
Metal-ceramic crowns and bridges are important because removing a tooth disrupts the balance and function of the remaining teeth. Adjacent teeth start to shift and lean into the empty space, directly jeopardizing their health and longevity. Besides negatively affecting the health of teeth and gums, it also represents a significant aesthetic issue.
Maintaining Metal-Ceramic Crowns and Bridges
Hygiene of metal-ceramic crowns and bridges is crucial for their longevity. Besides using a regular toothbrush and toothpaste, interdental brushes or a water flosser can be very helpful. In addition to regular home hygiene, it is necessary to visit a dentist for professional teeth cleaning 1-2 times a year.
Are ceramic crowns fragile?
No. Ceramic crowns and bridges do not break easily. They can break if the bite is incorrect if the ceramic is made too thin, or if something hard like a fruit pit is bitten suddenly.
Are metal-ceramic crowns better than zirconia?
Metal-ceramic crowns have excellent physical properties and are very durable and strong. The only aspect in which zirconia crowns are better is aesthetics.
Are all-ceramic crowns or metal-ceramic better?
Both materials have their advantages and disadvantages. The most important thing is for the dentist to determine which material would better solve your problem.
Can crowns turn yellow?
No. Ceramics cannot change color over the years.
Can they last 30 years?
They can sometimes last up to 15 years and in some cases even 20. Over the years, gum recession often occurs, which is why they need to be replaced, not because of the material.
Are metal-ceramic crowns prone to cavities?
The tooth under the crown can develop cavities in two cases: if the gums have receded or if the crown was placed on a tooth that was not healthy beforehand.
Do they look natural?
Yes. If made with great skill, which good dental technicians possess, they can look very close to natural teeth.
Why do they turn black?
With gum recession, the edge of the crown, which has a darker color, becomes visible. A new crown should not have a visible dark edge.
Can they be replaced?
Bridges and crowns can be replaced as often as needed.
Can they be placed on bad teeth?
No. If the teeth or gums around them are not healthy, no type of dental cap should be placed on them.
What food should be avoided?
Avoid unpopped popcorn kernels, fruit pits, olive pits, or using teeth as tools.
Veneers or metal-ceramic crowns: Which is better?
It depends on the position of the teeth and the bite, as well as whether the tooth is completely healthy or previously treated.
Common Alternative
Smaller-span metal-ceramic crowns or bridges can be replaced by all-ceramic (zirconia) crowns and bridges.
