Everything you need to know about zirconium dental crowns
Zirconium dental crowns have become a popular solution for replacing or restoring damaged or missing teeth. Combining strength, durability and aesthetics, they are particularly popular with patients and dentists alike. This article explores in depth the benefits of zirconium crowns, the installation process, their maintenance and the reasons for their success.
1. What is a zirconium crown?
Zirconium is a biocompatible material, meaning it is well tolerated by the body. It is particularly appreciated in the dental field for its robustness and its white color that imitates that of natural teeth. Unlike metal or ceramic crowns, zirconium crowns combine strength and aesthetics, making them ideal for visible teeth and molars subjected to high chewing pressure.
2. Advantages of zirconium crowns
Zirconium crowns offer several notable advantages, whether for aesthetic, functional or practical reasons.
Natural aesthetics
Zirconium has a color and translucency close to that of natural teeth. This means that a zirconium crown blends in seamlessly with other teeth, making it ideal for visible dental restorations, such as incisors.
Robustness and durability
Zirconium is an extremely strong material, capable of withstanding the pressures of chewing over a long period of time. It is therefore ideal for molars, which require a strong and durable crown.
Biocompatibility
Zirconium is known for its biocompatibility, which means it reduces the risk of allergic reactions or gum irritation. It is a safe material for patients with metal sensitivities.
Absence of metal
Unlike metal-ceramic crowns, zirconium does not have a metal base, which eliminates the risk of a gray rim appearing around the gum over time. This allows for a long-lasting and natural aesthetic result.
3. The process of placing a zirconium crown
The fitting of a zirconium crown follows a precise protocol to guarantee comfort, safety and aesthetics.
Initial consultation and planning
The first step is a consultation where the dentist assesses the health of the tooth requiring a crown. X-rays may be taken to check the structure and condition of the tooth. The dentist also discusses with the patient the different options, including the use of zirconium based on aesthetic and functional needs.
Tooth preparation
Before placing a crown, the dentist must prepare the tooth by cutting it so that it can receive the crown in a stable manner. Local anesthesia is usually used to ensure the patient's comfort during this step.
Fingerprinting
The dentist then takes impressions of the prepared tooth. These impressions are used to create a custom crown that will fit the tooth perfectly. With modern technology, it is possible to use digital scanners to obtain more accurate and comfortable impressions for the patient.
Making the crown
The impressions are sent to a laboratory where the zirconium crown is made. This step can take a few days. In the meantime, a temporary crown is placed to protect the prepared tooth.
Final pose
Once the crown is made, the dentist places and adjusts it to ensure that it is comfortable and fits properly. The crown is then permanently secured with dental cement, providing a long-lasting and stable solution.
4. Maintenance and longevity of zirconium crowns
Although a zirconium crown is very durable, regular maintenance is essential to ensure its durability.
Daily oral hygiene
It is important to maintain good oral hygiene to prevent infections and cavities that could affect the tooth under the crown. Daily brushing and flossing are essential to maintaining a healthy mouth.
Regular visits to the dentist
Regular checkups will ensure that the crown remains in good condition and that the gums around it are healthy. The dentist can also check the fit and perform professional cleanings to remove any plaque around the crown.
Avoid certain habits
To preserve the crown, it is recommended to avoid biting on hard objects such as pens or ice cubes, as well as eating particularly sticky foods that could put excessive pressure on the crown.
5. Why choose zirconium for a dental crown?
Zirconium crowns are ideal for many patients due to their unique properties. They are particularly recommended for those looking for a solution that is both durable and aesthetic.
Aesthetics and durability combined
For patients concerned about the appearance of their smile, zirconium is one of the best choices available because it combines natural aesthetics with the durability of modern materials.
Comfort and tolerance
People with metal allergies or sensitive gums often find zirconium a reliable and comfortable alternative. Unlike metals, zirconium does not cause adverse reactions.
Long term solution
With proper care, a zirconium crown can last for over ten years or more, making it a cost-effective long-term investment in maintaining your smile and oral health.
6. Innovations in zirconium crowns
Zirconium is a cutting-edge material that is constantly evolving. Thanks to technological advances, zirconium crowns are more precise, comfortable and aesthetic than ever before.
Injection molding technology
Some labs use injection molding techniques that produce even stronger and better fitting crowns.
Multilayer zirconium
The new multilayer zirconium crowns allow for better imitation of natural tooth color gradients, making them almost undetectable compared to natural teeth.
3D printing and computer-aided design
3D printing and CAD/CAM (computer-aided design) make it possible to manufacture custom zirconium crowns with unparalleled precision, optimizing comfort and fit for each patient.
In conclusion, zirconium crowns are a durable, aesthetic and well-tolerated solution to replace or restore damaged teeth. Do not hesitate to consult a professional to discuss this option and see if it fits your dental needs.
