All-ceramic crowns

All-ceramic crowns are the latest achievement in the field of prosthetics and aesthetic dentistry. These crowns are made on the foundation of zirconium oxide – a very hard and abrasion-resistant material, which is also biocompatible and well tolerated by our body.

Zirconium oxide has a hardness of 7.5 in a 10 degree Mohrs scale

The structure of zirconium oxide causes the light on all-ceramic crowns to behave like on your own healthy teeth. It allows us to achieve excellent aesthetic results, min. excellent natural translucency of crowns and natural light reflections.

Perfectly aesthetic crowns – without flaws and compromises

All-ceramic crowns – advantages and disadvantages.

Any defects and imperfections of crowns made with the classical method (ie using porcelain fused to metal) do not exist in the case of all-ceramic crowns . It is characterized by excellent aesthetics, smoothness, tightness and wide possibilities of characterization, which allows you to make crowns, which can not be distinguished from the crowns of your own teeth.

All-ceramic crowns are, therefore, a higher generation of crowns compared to traditional crowns on a metal foundation. They are a method of choice in aesthetic prosthetic works, especially in the anterior segment.

Old, unsightly metal crowns were replaced by all-ceramic crowns.

In addition to the obvious aesthetic advantages, all-ceramic crowns are also characterized by the perfect technical performance and the best tightness. We achieve this thanks to the use of a scanner that digitally and non-touch-up the prosthetic model (CAD / CAM system). On the basis of digital data sent further by the scanner and computer-processed, the prosthetic laboratory designs the shape of the zirconium substructure (CAD). In the next stage, the designed supplement is milled in a zirconium block by a computer controlled milling machine with an accuracy of a few dozen microns (CAM).

Scanner, computer software and milling machine – equipment for a modern prosthetic laboratory.

All-ceramic crowns are very universal prosthetic restorations – used both in situations requiring a single crown, ideally suited to the rest of natural teeth, as well as to the restoration of major deficiencies in side sections and work on implants.
