WHAT ARE DENTAL CROWNS AND WHY ARE THEY IMPORTANT?
Non-metallic crowns or non-metallic ceramics represent a type of high-tech compensation made entirely of ceramics. They can mimic the natural characteristics of teeth and permeate light as a natural tooth. Non-metallic ceramic crowns ideally fit into the dental array, especially in situations where all teeth are not replaced, but only some of them can not be distinguished. They represent a combination of top quality and durability of compensation.
Non-metallic crowns are made of biocompatible materials, which means that they do not cause any allergic reaction of the surrounding tissues and allow gingival formation as in natural teeth. Metal-free ceramics are a combination of superior quality and durability.
The mechanical properties of metal-free ceramics are similar to those of metal-ceramic crowns, but the advantages are far greater. Metal-ceramic crowns have a metal alloy inside, with ceramic on the outside for aesthetic effects, while metal-free crowns are entirely made of ceramic or have zirconium as a substrate
ABOUT MATERIALS THAT CROWNS ARE MADE OFF
In most cases, metal-free crowns are made of zirconium or lithium disilicate ceramics. This produces a crown that is made of a material that is semi-translucent as light and resistant as a natural tooth.
Zirconium crowns are a very popular type of metal-free replacement. Zirconium has exceptional mechanical properties, is white in color and is one of the most solid materials. It was initially used in space technology, and after extensive research, has found application in some branches of medicine, e.g. in orthopedics when making artificial hips.
Zirconium crowns have excellent aesthetic and mechanical properties. He experienced his expansion in dentistry due to the possibility of constructing large span bridges. With the advent of this material, a change was made in the technology of making crowns and bridges, as well as the emergence of crowns of lithium disilicate ceramics, which also has outstanding aesthetic properties.
