Zirconium dentures meet the highest aesthetic demands. Because zirconium artificial teeth are so perfect like natural teeth that only the dentist can tell the difference.

By means of an individual layering technique of the ceramic material, almost any shade can be matched to the natural tooth shade.

Like fine porcelain, zirconium lets light shine through and also has an equally smooth surface. Therefore, the structure of the enamel of the artificial tooth is similar to that of its natural model.

What is a zirconium crown?

The zircon crown is a dental prosthesis made of zirconium oxide and manufactured without metal. Zircon crowns and zircon bridges are translucent and tooth-coloured like natural teeth.

Zirconium crowns are mainly used in front teeth but also in posterior teeth as a replacement for crowns because they can be easily adapted to natural teeth. A zirconium crown is extremely biocompatible, stable and, in addition to bioesthetics, durable and well-tolerated.

Zirconium crowns consist of zirconium oxide, a chemical substance for high-performance ceramics that counteracts cracks. Zirconium oxide all-ceramics today set new standards in dental care because ceramics are white and metal-free. Much of what was only possible with metal in the field of dental prostheses can now be produced 100% metal-free with a maximum of safety and precision for the patient in biocompatible zirconium ceramics, which has a great advantage in cases of metal allergy. Zirconium oxide offers a very high flexural strength and crack toughness. Zirconium ceramics are therefore very suitable for the production of all-ceramic crowns and all-ceramic dental bridges. Zirconium oxide is characterised in particular by its high light transmission and excellent biocompatibility.

Advantages of a zirconium dental crown:

  • The zirconium dental crown is a completely metal-free dental prosthesis and is particularly suitable for people with allergies.
  • The zircon crown made of zirconium is of high quality and has a high strength.
  • Zirconium oxide crowns are very durable
  • The zirconium crown made of zirconium is of high quality because zirconium dioxide (zirconium) sets itself apart from other all-ceramic materials due to its enormously high strength values.
  • The zirconium tooth crown is popular in bioprosthetics, because the zirconium with the porcelain veneer is translucent and achieves an optimal naturalness in the color play (natural appearance).
  • In contrast to metal-ceramic crowns, zircon crowns have no black edges on the neck of the tooth due to their high light transmission, even if the gums retreat due to the gum recession in old age.

Disadvantages of a zirconium dental crown:

A disadvantage of the zirconium crown is the price or cost of dental prosthesis, because the cost of tooth restoration is higher than the price of a metal-ceramic crown. Zirconium crowns are usually cheaper than gold ceramic crowns. When the gold price rises, zirconium ceramic crowns become more and more attractive in restorative dentistry or “bioesthetic dentistry”, where the use of high-performance ceramics with single crowns or dental bridges is used especially in the anterior region. The gold-ceramic crown also has price disadvantages compared to the metal-ceramic crown, but as a “bioesthetic dental prosthesis”, the advantages of the zirconium crown outweigh those of all other crown types.


Before the actual treatment begins, impressions of the dental situation in the patient’s mouth are taken. These are used to fabricate the crown and – if necessary – a temporary restoration. If a patient has decided on a tooth-coloured crown, the exact shade of the teeth must also be determined. This can be very difficult and time-consuming as a tooth has several shades. In particularly difficult cases, the dental technician should look at the oral situation for himself in order to be able to fabricate the prosthesis (crown) individually and adapted to the remaining tooth population.

Under local anaesthesia, the tooth is ground for the insertion of a crown (preparation). If caries is present, it is removed. The resulting defect is closed with a filling. This serves to stabilise the tooth and also ensures that the prepared (ground) tooth stump provides an improved hold for the tooth crown. For an optimal hold of the tooth crown, the dentist has to remove damaged and partly healthy tooth substance. The ground tooth stump is then dried.

In order to obtain an exact impression of the ground tooth, the gum must be pushed back slightly. The more accurate the impression and the resulting working model are, the better the crown will fit on the tooth stump. In addition, the dental technician needs an impression of the opposing jaw in order to determine the correct bite height of the crown. The fabrication of a crown in our clinic usually takes four to eight days (?). As an alternative to fabrication in the dental laboratory, there is the CeRec process (CeRec is the abbreviation for Ceramic Reconstruction and is a computer-aided process for the fabrication of tooth-coloured, high-quality all-ceramic reconstructions) for fixed ceramic dental prostheses. This manufacturing process is very precise and saves time.)

Until the actual crown is inserted, the prepared tooth must be protected against external influences. A temporary restoration is used for this purpose. Without the temporary, the tooth stump would be so sensitive that only the breath would cause severe pain. The “transitional crown” supports the occlusion and protects against irritation of the tooth nerve. Most temporary restorations are made of plastic (composite).

In the second session the almost finished crown is “tried on” on the prepared tooth. The patient decides whether the procedure should take place under local anaesthesia. In the visible area of the front teeth, colour and shape corrections may be necessary. In this case, another session would be necessary.

The dentist checks the following factors:

  • The edge termination of the crown
  • Contact with the opposing jaw
  • The contact to the neighboring teeth
  • Optical insertion into the dental arch

The crown must merge harmoniously into the tooth stump. If the dentist does not work precisely enough, it can happen that the crown margin has cracks and steps. At this point, plaque and food residues can collect or germs can penetrate which lead to secondary caries. If all the adjustment criteria are correct, the crown is fixed firmly to the tooth stump using a special cement.
