ZIRCONIUM CROWNS

What are zirconia crowns?

Advances in the strength and appearance of zirconia crowns have made them the leading choice for restoring broken or destroyed teeth. Zirconia used in dentistry is zirconium oxide. This is a material that combines the strength of metal with the aesthetics of ceramic crowns.

Advantages

The main advantages of zirconia crowns are:

  • Excellent aesthetics
  • Robustness and durability
  • Precision manufacturing using CAD/CAM technology
  • Biocompatibility: being metal-free significantly reduces the likelihood of allergic reactions

Partial crowns (inlay and onlay)

If you have a large obturation (filling) or a partially broken tooth, a porcelain inlay or onlay may be the perfect solution for you. These restorations are an excellent alternative to a full crown.

2 VISITS

What to expect:

On your first visit to Karadzhovi Dental Club, we will completely numb the treated tooth with a local anesthetic. The tooth will then be prepared as conservatively as possible for the zirconia crown. After careful evaluation of the shape and contour, we will take an impression of the prepared tooth.

We will make a temporary crown which we will cement. The purpose of temporary crowns is to protect and restore function and aesthetics while our competent dental technicians craft your crown.

During the second visit, we will remove the temporary crown. We will make a test to see if the zirconium crown fits the prepared tooth. We will cement it and remove the excess cement. You’ll get all the instructions you need to properly care for your new crown!

Crowns – what are they?

Crowns – metal-ceramic, ceramic or zirconium, are called the structures that “dress” the tooth on all sides. With their help, destroyed teeth are restored and given an aesthetic appearance. Teeth with zirconia, ceramic or metal-ceramic crowns are extremely strong, resistant to the test of time and beautiful – which is why they are suitable even for front, visible teeth. They are made of different materials – there are zirconium, ceramic and metal-ceramic crowns, which are distinguished by different durability. It is up to the patient and the dentist they trust to decide what type of crowns – metal-ceramic, ceramic or zirconia – will be chosen for their particular case.

Ceramic crowns – advantages of the material

Crowns 1

Crowns – ceramic crowns do not cause allergic reactions

Ceramic crowns are distinguished by a high degree of aesthetics. They can be made in a colour close to natural, which will make them indistinguishable from the surrounding natural teeth. Ceramic crowns are made of a material that has the ability to transmit light rather than reflect it. Our natural teeth also have this property. Therefore, the material from which the ceramic crowns are made looks very aesthetic and natural. The same cannot be said for metal-ceramic crowns, which reflect light and do not look as natural, but they do have other qualities, which will be discussed shortly.

A great advantage of ceramic crowns is that the material does not interact with the gum, therefore it does not cause any allergic reactions and does not change under the influence of various substances that are present or fall into our mouth – the color and structure of ceramic crowns remain the same. This is another advantage over metal-ceramic crowns – with metal-ceramic crowns there is a risk of oxidation or allergic reactions. However, metal-ceramic crowns have other indispensable properties, which will be discussed in a moment.

 

 

Strength and durability of ceramic crowns

Ceramic crowns are made either manually by a dental technician or with the help of a computer. In both cases, several layers of the material are applied, which have different qualities and functionalities, and the goal is the most natural-looking ceramic crowns. Aesthetics are highly emphasized in the fabrication of ceramic crowns. Ceramic crowns are very strong and durable, but they are more suitable for front, visible teeth, not for back chewing teeth – for them it is better to bet on metal-ceramic crowns. With proper maintenance, ceramic crowns last a minimum of ten years – in most cases, more than a decade – while maintaining their appearance and function. This also applies to metal-ceramic crowns.

Crowns – metal-ceramic crowns are an ideal choice for back chewing teeth

Metal-ceramic crowns include a metal base, which adds incredible strength to the structure, and an outer ceramic layer for an aesthetically pleasing appearance.
Metal-ceramic crowns are among the most common crowns in general. The reason is that they offer strength, durability and satisfactory appearance at a low price. All-ceramic crowns are more expensive than metal-ceramic crowns, but their appearance is flawless. Metal-ceramic crowns, although rarely found to be deficient in appearance, their irreplaceable strength makes them suitable for the back teeth, which are most stressed when chewing.

Strength and durability of metal-ceramic crowns

Metal-ceramic crowns rely primarily on strength. This is the reason why metal-ceramic crowns are used so often when it comes to the treatment of the back chewing tooth. There are almost no other constructions other than metal-ceramic crowns that can withstand the daily force applied to them by chewing for decades. Metal-ceramic crowns can also be placed on front teeth, of course, but this is not the optimal option. The best solution would be ceramic crowns on the front and visible teeth and metal-ceramic crowns on the back chewing teeth.

 

Zirconium crowns – advantages of the material

Crowns – zirconium crowns are strong and durable

Zirconia crowns have many advantages over other types of crowns available on the market. First, the material from which they are made – zirconium, is a natural mineral – of completely natural origin. The zirconium used to make dental structures is usually part of a compound that makes it stronger and more durable. They are not inferior in strength even to metal-ceramic crowns, and their beautiful appearance is unattainable for metal-ceramic crowns.

Another advantage is that these constructions are fully compatible with the human body, as they are made of minerals that are present in human bones. Guaranteed biocompatibility is a very important advantage over metal-ceramic crowns, which, although rare, can still trigger some allergic reactions.

A very important advantage of zirconia over metal-ceramic crowns is the beautiful appearance that never changes. With metal-ceramic crowns, it is possible that at some point the metal oxidizes, which leads to graying and a less than aesthetic appearance of the teeth. This does not happen with zirconium structures, they do not change over time and do not react with other substances. When it comes to the natural appearance of the teeth, zirconia is again one breast ahead of metal-ceramic crowns because, like ceramics, it has the ability to transmit light rather than reflect it. This makes zirconia crowns much more beautiful and natural looking compared to metal-ceramic crowns.

Crowns – placed within 2 procedures

Constructions made of zirconia compound are extremely durable, strong and long-lasting – like metal-ceramic crowns, and in some cases even more so. Unlike metal-ceramic crowns, however, they do not scratch, break, stain, oxidize, react with substances, or change at all over the years. There are different types of zirconia dental constructions, some of which last a lifetime without changing their aesthetic appearance and quality.

Procedure of placing crowns

The placement of dental constructions usually occurs within two visits. At the first visit, the tooth or teeth to be treated by crown placement are prepared and precise impressions are taken. A local anaesthetic may be administered prior to this procedure to avoid discomfort. A temporary crown is then fabricated and placed to perform all the functions of the tooth until the permanent crown is fabricated.

At the second visit to the dental specialist we trusted, the temporary crown is removed and the permanent crown is placed and cemented in its place. After verifying that the crown fits perfectly in place, the dental professional gives the patient instructions on caring for the new crown and that concludes the procedure.
