Dental crowns are generally classified into two main categories: metal-supported and zirconia-supported restorations. Zirconia belongs to the group of restorations that do not contain metallic coloring. Zirconium reacts with oxygen in special furnaces to form zirconium dioxide. While feldspathic porcelain can be fired onto zirconium dioxide, today highly aesthetic restorations can also be achieved using multilayer zirconia without the need for porcelain layering. Zirconium dioxide itself is also used as a dental restoration material. The advantages it offers have made zirconia one of the most popular crown materials in recent years. However, it should be noted that the porcelain fired onto the underlying framework is essentially the same in both zirconia-supported and metal-supported porcelain restorations. In metal-supported porcelain crowns, feldspathic porcelain is fired onto a metal framework, while in zirconia-supported crowns, feldspathic porcelain is fired onto a zirconia framework.
Zirconia crowns are frequently preferred by individuals who have significant tooth structure loss requiring crowns or those seeking a more aesthetic appearance. Compared to metal-supported restorations, zirconia is more commonly preferred for anterior teeth, although it is not always the ideal option. It provides highly successful aesthetic results; however, glass ceramics remain the most aesthetic materials available. Zirconia is the primary choice for individuals with metal allergies. It can also be used to replace missing teeth and demonstrates excellent compatibility with gum tissues. Following treatment, zirconia crowns require the same level of care and maintenance as natural teeth. Dentrum Private Oral and Dental Health Polyclinic in Adana explains everything you need to know about zirconia crowns.
What Is a Zirconia Crown?
A zirconia crown is a modern dental restoration that offers one of the closest appearances to natural teeth while providing highly aesthetic and successful results. It is created by applying specially prepared porcelain onto an extremely durable zirconia substructure. Compared to metal-supported crowns, zirconia restorations provide a much more natural appearance and superior light transmission. They are especially preferred for anterior teeth due to aesthetic concerns.
How Is a Zirconia Crown Applied?
Zirconia crown treatment is an aesthetic dentistry procedure performed by dental professionals. First, any dental issues are identified. Before treatment begins, local anesthesia is administered to prevent discomfort and sensitivity in the treatment area. The teeth are then reduced in size until they reach the appropriate dimensions for crown placement. Impressions of the prepared teeth are taken either manually or using digital technology. A shade is selected from a color guide according to the patient’s preferences. During the fabrication process, temporary crowns are placed to prevent sensitivity and maintain aesthetics. Zirconia crowns are typically manufactured within three to five days. Once the patient approves the final result, the temporary crowns are removed and the zirconia restorations are bonded into place. After the bonding procedure, patients should avoid eating for approximately thirty minutes. Finally, patients are expected to attend regular follow-up appointments.
How Does the Treatment Process Work?
Zirconia crown treatment can generally be completed within 7–10 days. The treatment stages are as follows:
Preparation and Impression – At this stage, a controlled amount of tooth structure is removed, slightly reducing the size of the teeth. Precise impressions are then taken using digital impression systems.
Temporary Crowns – Temporary crowns are placed on the same day the teeth are prepared. This allows patients to continue their daily and social lives without being left without teeth.
Try-In Appointment – The zirconia framework prepared in the dental laboratory is tried in the patient's mouth. Its shape, function, and color are carefully evaluated.
Cementation – Once everything is finalized, the crowns are permanently bonded to the teeth using special dental adhesives.
Characteristics of Zirconia Crowns
Zirconia crowns can be applied to both upper and lower teeth. While strength and durability are the primary concerns for posterior teeth, aesthetics are equally important for anterior teeth. Zirconia is a material that successfully meets both requirements. The advantages of zirconia crowns include:
- Absence of a metallic framework and no dull appearance
- Partial light transmission for a natural look
- Extremely strong structure due to specialized firing processes
- High resistance to corrosion
- Resistance to wear, cracks, and fractures
- Hypoallergenic properties
- Excellent compatibility with gum tissues and support for gum health due to biocompatibility
- No alteration of taste in the mouth, unlike some metal-supported restorations
- Long-term durability and safe use
- Much lower likelihood of discoloration compared to natural teeth
- No risk of metal-related allergic reactions
- Smooth and polished surfaces that resist plaque accumulation
- Low thermal conductivity, reducing sensitivity to hot and cold temperatures
- Reduction of bad breath and prevention of dark gum discoloration when proper oral hygiene is maintained
Who Can Get Zirconia Crowns?
Many individuals who are dissatisfied with the appearance of their teeth and prefer not to have metal restorations choose zirconia crowns. They are also the first choice for patients with metal allergies. However, this treatment is generally not recommended for individuals under the age of 18 whose growth and development have not yet been completed. Zirconia crowns are commonly used in patients with the following conditions:
- Gaps between teeth
- Tooth decay
- Missing teeth
- Teeth damaged or fractured due to trauma
- Patients who did not achieve satisfactory results from teeth whitening
- Patients experiencing aesthetic concerns due to gum recession
- Discolored teeth
- Misaligned teeth
- Teeth requiring bridges or crowns
Zirconia Crown Models and Lifespan
The lifespan of zirconia crowns varies depending on several factors and differs from person to person. Some individuals may use them for five to ten years, while those who maintain proper oral hygiene can potentially use them for a lifetime. Patients who attend regular dental check-ups and take good care of their oral health can enjoy their zirconia restorations for many years without problems. Treatments performed in unqualified clinics often lead to unsuccessful outcomes, shorter restoration lifespans, and potential health complications.
To achieve a harmonious smile aesthetic, tooth shape irregularities must be corrected. Composite fillings may be sufficient in some cases, while glass ceramic or zirconia crowns may be recommended in others. During the trial stages of porcelain or zirconia crown treatments, modifications can be made according to the patient’s preferences.
The Difference Between Zirconia Crowns and Metal-Supported Crowns
The primary difference lies in the framework material used. In zirconia crowns, zirconia serves as the supporting material beneath the porcelain. In contrast, metal-supported crowns use a metal framework beneath the porcelain. Due to its light-transmitting properties, zirconia provides a more natural and aesthetic appearance than metal. Metal-supported crowns block light transmission, resulting in a more opaque and matte white appearance.
Zirconia crowns demonstrate excellent compatibility with gum tissues and contribute positively to gum health. On the other hand, metal frameworks may be less compatible with the gums and can sometimes cause dark discoloration along the gum line. Metal restorations may also trigger allergic reactions and contribute to unpleasant tastes or odors in the mouth. These issues are generally not encountered with properly fabricated zirconia restorations.
Who Is a Suitable Candidate for Zirconia Crowns?
- Zirconia crown treatment may be suitable for:
- Teeth with severe discoloration
- Anterior teeth requiring aesthetic enhancement
- Individuals with fractured or worn teeth
- Patients with large gaps between teeth who wish to close them
- Individuals with weakened tooth structure due to large fillings
- Patients with metal allergies
- Individuals seeking a comprehensive smile makeover
However, a comprehensive dental evaluation is essential before deciding on treatment.
Zirconia or E-Max?
One of the frequently discussed topics in aesthetic dentistry is the difference between zirconia crowns and E-Max restorations.
Zirconia crowns stand out for their durability and suitability for use in posterior teeth. They can also be used in bridge restorations and are frequently preferred because of their longevity.
E-Max restorations, on the other hand, are known for their superior light transmission, thinner structure, and ability to be applied with minimal tooth reduction. The choice between these materials depends on the patient's oral condition, needs, and expectations.
What Should Be Considered After Zirconia Crown Treatment?
To maintain the long-term success of zirconia crown treatment, several recommendations should be followed:
- Brush your teeth twice daily
- Use dental floss and mouthwash regularly
- Attend dental check-ups every six months
- Avoid using your teeth to crack hard foods or shells
- If you suffer from bruxism (teeth grinding), use a night guard
- Limit smoking
With proper and regular care, zirconia crowns can be used successfully for many years.
