Dental crowns

Dental crowns are permanent prosthetic solutions that cover a damaged or weakened tooth to restore its strength, shape, and natural appearance. They are used in cases of extensive damage, following caries, fractures, or endodontic treatment.

Aesthetic result with dental crowns

Ceramic crowns are made of ceramic material, which is why patients often refer to them as "porcelain crowns". They are associated with a natural tooth-like appearance, giving patients a sense of confidence and comfort.

Types of dental crowns

There are several types of ceramic crowns, each with its own unique features and advantages.
 
  • Metal-ceramic crowns

    Metal-ceramic dental crowns have a metal core covered with a layer of ceramic, combining the strength of metal with the natural appearance of ceramic.
  • Zirconia dental crowns

    The main advantage of zirconia ceramic crowns is their exceptionally natural look, often indistinguishable from real teeth. Their strength is comparable to metal-ceramic crowns. These crowns offer an ideal aesthetic solution along with long-term durability and function.
  • Metal-free dental crowns

    Completely made of ceramic, metal-free dental crowns deliver a highly aesthetic result thanks to their translucency and lifelike tooth reproduction.

When are dental crowns placed?

Dental crowns are used when a tooth is partially damaged and a filling is not sufficient to restore the missing structure.

They are also used as prosthetic replacements in cases where only the tooth root is preserved while the crown is entirely destroyed. In such cases, post-and-core buildup is necessary to enable placement of a dental crown on the root. Ceramic crowns can also be placed when a tooth is missing or has been extracted - however, in these situations, a dental implant must be placed first to serve as a foundation between the jaw and the ceramic crown.

The choice of which type of dental crown to use depends on several key factors, including the condition of the tooth, functional requirements, the patient’s aesthetic preferences, the position of the tooth in the mouth, and the material’s strength and durability.

The patient’s budget also plays an important role, as different types of crowns come at different costs. For example, metal-ceramic crowns are often chosen for back teeth where greater strength is needed, while metal-free ceramic crowns are preferred for front teeth due to their superior aesthetics.

 

Zirconia crowns

Zirconia crowns are made using zirconium oxide as the core material. Known for its exceptional strength and biocompatibility, zirconium oxide is widely used in dentistry for fabricating dental crowns. Outstanding aesthetics and a natural appearance are the main advantages of zirconia dental crowns.

This material is highly resistant to fracture and wear, and its white color and translucency allow the crown to closely mimic the look of a natural tooth.

Traditional zirconia crowns have ceramic layers applied over a zirconia core, enabling high aesthetic customisation and a natural tooth-like appearance.

There are also monolithic zirconia crowns, made entirely from a single block of zirconia. Unlike layered zirconia crowns, monolithic zirconia does not replicate the natural look of a tooth as convincingly, due to the uniformity of the material.

Monolithic zirconia crowns are often used on posterior teeth, where strength is more important than aesthetics.

Zirconia crowns generally come at a higher cost compared to other types of crowns, due to their superior durability and visual appeal.
 

Metal-ceramic crowns

Metal-ceramic crowns are a traditional choice in prosthetic dentistry due to their reliability and long-term durability.

These crowns consist of a metal alloy base covered with a layer of ceramic.

The combination of metal and ceramic enables the creation of strong and long-lasting crowns capable of withstanding significant chewing forces.

One of the key advantages of metal-ceramic crowns is their ability to provide good aesthetics while maintaining full functionality.

The ceramic layer can be adjusted in both color and shape to match the surrounding teeth, resulting in a natural appearance.

However, the metal substructure can sometimes limit the crown’s translucency, making it appear less natural compared to all-ceramic or zirconia crowns.

The main drawback of these crowns is the appearance of a dark line along the gum line, which can occur if the gums recede over time.

Why choose Centrodent for dental crowns?

At Centrodent, dental crowns are designed with a focus on function and long-term durability. We follow the principles of minimally invasive therapy and use crowns only when they are truly necessary for prosthetic rehabilitation, not solely for aesthetic purposes.

  • We follow professional standards

    Dental crowns are placed only when truly necessary, based on the patient’s functional needs. Our approach to tooth preparation is minimally invasive - we avoid unnecessary devitalisation and carefully preserve interjaw relationships to ensure optimal function and long-term success.
  • Natural-looking dental crowns

    We prepare the tooth to allow enough space for a crown that looks natural, using only layered ceramic. Special attention is given to harmonising the crown with the patient’s skin tone and facial structure. Our goal is to create teeth that look completely natural, without an artificial appearance.
  • We don't grind healthy teeth

    Aesthetic reasons alone are not sufficient justification for placing ceramic crowns. We never grind healthy teeth purely for cosmetic purposes. Crowns are primarily a prosthetic solution and should be used only to restore tooth function.

Procedure overview and treatment duration

This stage begins with a thorough examination and assessment of the patient’s dental condition, including x-rays and other diagnostic procedures to gain a complete understanding of oral health.

Following diagnostics, we discuss the available types of ceramic crowns with the patient, taking into account both functional needs and aesthetic expectations.

Based on this conversation and the patient’s preferences, a decision is made regarding the type of ceramic crown to be placed.

To prepare the teeth for crowns, a small amount of tooth structure is gently reduced to create space for the new ceramic crown.

After that, temporary crowns are placed to protect the prepared teeth while the final ceramic crowns are being crafted in the dental laboratory.

These temporary crowns allow the patient to maintain normal function and protect the teeth during this interim period.

The third phase involves placing the ceramic crowns, usually about two weeks after the teeth have been prepared.

This timeframe may be extended if any teeth required treatment before crown placement. If a tooth has undergone treatment, we allow extra time to ensure it responds well to therapy.

Crowns are never placed immediately after treatment - sufficient time is needed to confirm the tooth’s stability and the success of the procedure before final placement.
 

Common questions about dental crowns

Temporary dental crowns serve as short-term protection for prepared teeth while the final prosthetic crown is being made.
They also allow patients to maintain normal tooth function and appearance during the treatment period.

There are several types of temporary crowns, depending on the material:
  • Acrylic temporary crowns can be made directly in the dental office or in a dental lab, depending on the patient’s needs.
  • Printed temporary crowns are produced in a dental lab using digital impressions and precise 3D printing technology.
  • PMMA temporary crowns (polymethyl methacrylate) are also lab-made and known for their strength and durability. They are often used during longer prosthetic treatments.
Temporary crowns are placed immediately after tooth preparation. Their colour, shape, and size are not identical to ceramic crowns. While wearing them, patients may experience sensitivity to hot, cold, or sweet foods.

It’s important to note that they are cemented using temporary cement, which takes about 30 minutes to fully set. During that time, chewing should be avoided. While wearing temporary crowns, patients should stay away from chewing gum, sticky or hard candies, nuts, and biting into hard foods, as these can cause the crown to crack or come loose.

Temporary crowns are not intended for long-term use.
 

Choosing the right type of dental crown depends on several factors, including aesthetics, the condition of the supporting tooth, biocompatibility of the material, and individual bite characteristics—not solely on financial considerations.

For example, while metal-free ceramic crowns are often recommended for their superior aesthetics in the front of the mouth, they may not always be the best option for back teeth, where stronger chewing forces are present.

Metal-based crowns offer added strength, making them suitable for posterior teeth. However, they can sometimes lead to the appearance of a dark margin over time due to gum recession. On the other hand, crowns with a zirconium oxide base and full-ceramic crowns provide excellent aesthetics and natural translucency. They are ideal for front teeth and do not cause gum irritation or allergic reactions.

The optimal choice of crown should be made in consultation with your dentist, who will recommend a solution based on a clinical examination, balancing both functional and aesthetic needs for your specific case.

Zirconia crowns are among the most commonly requested solutions by patients seeking a combination of top-tier aesthetics and long-term durability.

Patient experiences with zirconia crowns are overwhelmingly positive. Zirconia offers a highly natural tooth-like appearance while being extremely resistant to wear.

Many patients report that after receiving their crowns, they feel like they’re chewing with their natural teeth, without discomfort. This restores their confidence in smiling and improves everyday functions like eating.

One of the most appreciated benefits is that zirconia ceramic crowns are metal-free, which means they don’t cause dark lines along the gum margin - a common concern with metal-ceramic crowns.

During preparation for zirconia crowns, it’s important to shape the tooth with a "shoulder margin," which ensures a stable and precise fit for the crown.

Equally crucial is that the teeth are prepared in parallel. If not, it can complicate crown placement or lead to poor adaptation, allowing cement to seep underneath the edge of the crown. This can eventually cause secondary caries and gum irritation.

That’s why careful planning and precise fabrication are the foundation of successful zirconia crown therapy and long-term patient satisfaction.

At Centrodent, we use a digital scanner to verify the parallelism of prepared teeth, ensuring they are shaped with absolute precision.

When discussing the cost of zirconia ceramic crowns, it's important to understand that there are different types. The type of zirconia crown directly affects both the final appearance and the price.

The two most common types are monolithic zirconia crowns and layered zirconia ceramic crowns, which have additional ceramic layers applied.

Monolithic crowns are made from a single block of zirconia. They are very durable and suitable for back teeth where chewing forces are strongest, but they are aesthetically simpler and often can’t replicate the natural translucency and depth of real teeth.

At Centrodent, we do not use monolithic zirconia crowns because we believe they are not the most aesthetically pleasing, especially for patients seeking a natural and harmonious smile. Monolithic zirconia crowns often appear flat and lifeless.

Instead, we exclusively use layered zirconia crowns, where hand-layered ceramic is applied to a strong zirconia base. This allows us to achieve a high level of aesthetics with light-transmitting properties that closely mimic natural teeth.

Therefore, the price of a zirconia crown depends on which type is being made - both have a zirconia base, but layering ceramic requires additional lab work and expertise.

However, the price doesn’t depend on the material alone - what matters most is proper tooth preparation by the dentist.

The tooth is prepared with a so-called shoulder margin to ensure the crown fits precisely. If the preparation is not done properly and the teeth are not parallel, it can lead to poor crown adaptation, cement leakage, gum irritation, and secondary caries.

This is why the price of a zirconia crown includes not just the cost of quality materials and lab work, but also the professional precision of the dentist throughout every stage of treatment.

Zirconia crowns are made entirely from a single block. This means they do not have an additional ceramic layer that would give them a natural look. They are fully constructed from zirconia.

The aesthetic effect of zirconia crowns is quite limited because they lack the translucency and light reflection of natural teeth, which makes them appear unnatural and “heavy” in the smile.

For this reason, monolithic zirconia crowns are used only in the posterior part of the jaw, where the lack of aesthetics is less noticeable.

In contrast to zirconia crowns there are zirconia ceramic crowns, which are a much higher quality solution in terms of aesthetics.

With this type of crown a ceramic layer, commonly referred to by patients as “porcelain”, is applied over the zirconia base.

This ceramic layer allows for translucency, natural light reflection and an accurate imitation of tooth color. It is precisely this layer that makes the crown look like a real tooth rather than artificial and uniform.

The price difference between these two types of crowns comes from this ceramic layer, which is applied to more faithfully replicate the appearance of natural teeth and achieve a more natural aesthetic outcome than full zirconia crowns.

It is extremely important that patients know in advance exactly which type of crown they will receive, since the aesthetic difference is significant.

At Centrodent we produce only zirconia ceramic crowns, because we believe that monolithic or fully zirconia crowns cannot meet aesthetic requirements or convincingly reproduce the natural appearance of teeth.
