Ceramic crowns - questions and answers

Ceramic crown is a dental restoration that fills the gap in the dental arch usually formed by a loss of a natural tooth. It is all-ceramic and has excellent aesthetic properties.

The main difference is that the ceramic crown is made only of ceramics, whereas metal-ceramic crown has a base made of metal alloy (white gold, titanium, chrome, cobalt, nickel) completely covered with a layer of ceramics. Crowns made of ceramics are more translucent and are a better imitation of the natural tooth.

Ceramic crowns are fabricated using a CAD/CAM system. After the tooth is prepared, an image is made with a special device and is sent to dental laboratory where a crown, very similar to the natural tooth, is fabricated out of one ceramic block using a precise calculation and choice of material as well as a special dental drill. After the crown formation is completed, dental laboratory technician finishes the new tooth with his hands until it is identical in shape and color to the natural tooth.

Artificial ceramic crown, after passing the fitting test as well as shape and color compatibility, is bonded to the tooth using a special dental cement. A crown placed this way integrates with the natural tooth.

Durability of a crown depends on the quality of fabrication as well as the quality of oral hygiene during the years of usage. Complying with all the dentist's guidelines, a ceramic crown can last a few decades.

Maintenance of artificial ceramic crowns is no different than maintenance of natural teeth. Regular brushing, using dental floss, mouth wash and regular removal of tartar and plaque will extend their durability.

Zirconium is a special ceramic material of extraordinary physical and aesthetic properties. Because of its extreme strength it is suitable for restorations in each region of the oral cavity. It can be placed on dental implants or on prepared natural teeth.

IPS e.max® ceramics is top-quality ceramic material for fabrication of dental crowns. It is primarily used in frontal region, when dental crowns are placed on prepared natural teeth.

Although both materials have almost identical qualities, when we talk about functionality and aesthetics, they are used depending on the wish of the patient and the region of placement. IPS e.max® ceramics is mostly used for frontal region and are being placed primarily on natural prepared teeth because it gives the best results, whereas zirconium is used for all regions of the jaw as well as for placement on dental implants.

Usage of all-ceramic crowns has a number of advantages over metal-ceramic combinations, and the most important are:

  • biocompatibility
  • translucence
  • no allergic reactions to metal

Biocompatibility is human body's ability to accept foreign body without any danger of rejection.

Allergic reactions to ceramics are possible, but are extremely rare. We haven't had any cases of allergic reactions in our clinic to this day.

It is definitely better to place it on a prepared natural tooth. No artificial material can replace your natural tooth. Besides, a ceramic crown will give a better aesthetic result if placed on a prepared natural white tooth than if placed on a dental implant .
