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. 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.
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.
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).
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.
