Zirconia crowns – steps of the treatment
The use of zirconia crowns is recommended for treating extended tooth decay or chipping. The tooth is generally salvageable despite the toothache and the discoloration, therefore the zirconia crown is a perfect solution for the restoration. Below, you will find all the details about zirconia crowns and information about the steps of the treatment.
What is a dental crown?
Crowns are used in dentistry in order to replace damaged teeth. The crown is placed onto the remaining part of the tooth above the gumline, but they can also be placed onto implants. Their shape and colour match perfectly with the patient’s natural teeth. Crowns also can be used to protect devitalized teeth from further damage. Crowns are often used for aesthetic reasons too, correcting discoloured, misshapen teeth.
The steps of the placement of the crown
- Local anesthesia is used on the area of the treatment
- After the patient is numbed, the first step is the preparation and reduction of the tooth.
- The dentist takes an impression of the abutment and the surrounding teeth.
- Until the zirconia crown is prepared, a temporary crown is placed onto the tooth.
- The zirconia crown is prepared within a couple of days in our laboratory with CAD-CAM technology.
- The dentist applies the zirconia crown onto the abutment and fixes it with a special dental cement.
When is a dental post necessary?
A dental post is recommended when a big part of the natural crown is missing and basically only the roots of the tooth remain, because in this case there is not enough natural tooth to form the abutment and support the zirconia crown.
If the root canals of the tooth are in bad condition, the tooth probably has to be removed and an implant or a bridge is needed to replace the missing tooth. However, in many cases a dental post can be a perfect solution as the post provides support for the zirconia crown.
In order to choose the best treatment, a panoramic x-ray is needed. Based on this, the dentist is able to determine the state of the root canals and whether the placement of a dental post is possible.
The prerequisite of the placement of a dental post is the devitalization of the tooth. The dentist places the dental post into the root canal, and – in case of a freshly devitalized tooth a couple of days later – takes an impression. The cast is sent to the laboratory where the zirconia crown is prepared. The crown is fixed onto the post with a special dental cement.
The advantages of zirconia crowns
Zirconia crowns are made of strong, durable material which makes them a long-lasting and aesthetically pleasing. Zirconia crowns are biocompatible and they do not contain metal, so they are suitable for patients with metal allergies too.
Zirconia crowns are made by a special, computerized system, using CAD-CAM technology. The process is almost entirely automatized, assuring excellent quality and minimal waiting time. In our laboratory, we only use high-quality materials for the zirconia crowns.
For patients with bruxism, grinding their teeth puts extra pressure on their teeth, however this is not a contraindication. Zirconia crowns are made of strong, durable material that can handle the additional pressure of teeth grinding. In some cases, the dentist can recommend using a mouthguard or nightguard to protect the teeth.
