For many dentists and patients who need dentures, the zirconium crown is regarded as a star among artificial dental crowns: it is metal-free and thus free of allergy risks and perfectly compatible with the body. In addition, a partial crown or full crown made of zircon meets the highest aesthetic standards: It’s color and its entire appearance can be replicated to those of the natural tooth perfectly.
Due to its characteristic shimmer and light translucency, the zirconium crown is visually indistinguishable from its own or natural tooth. Many patients, therefore, opt for a zirconium crown when the dentures sit in the visible area of the incisors, canines and anterior teeth.
Unlike crowned metal crowns, a zirconium crown cannot have dark edges on the tooth neck or gingival margin over time as the metal framework shines through.
When Is An Artificial Tooth Crown Used?
Tooth decayed teeth threaten to die if the dentist does nothing. If the tooth is already severely damaged, caries must be removed over a large area. What remains is then only a tooth stump, which can be used as a basis for a dental crown.
The dental crown is put on the affected tooth to a certain extent after preparation by the dentist and thereby firmly fixed. An important condition for this is that the tooth root is in an intact state and is still well rooted in the jawbone. Only then will the new crown have the necessary hold in the jaw.
Meanwhile, it is even possible to produce not only complete crowns but also complete dental bridges made of all-ceramics. It can be assumed that the importance and popularity of ceramic restorations will continue to increase in the future as well.
What Is Behind The Zircon Material?
The material name Zirkon is actually an abbreviation, as well as the also popular names zirconium, zirconium oxide or zirconium oxide.
Correctly titled, this modern high-performance ceramic is called zirconium (IV) oxide (ZrO2) or zirconium dioxide. As a highly compatible, highly stable and visually appealing dental material, this material has been established for years in aesthetic dentistry.
Zirconia has a lower thermal conductivity than metal. Its conductivity much more closely matches that of natural tooth substance, which gives it another advantage: its wearing comfort is very high, as the zirconia does not transmit stimuli such as heat or cold to the tooth nerve as much as metal. Even the electric tingling, which can be based on contact with other metals (cutlery, aluminum foil) of metallic dentures, cannot arise with a full ceramic crown.
How Is A Zirconium Crown Constructed?
A zirconium crown consists of a ceramic core of zirconia and a ceramic veneer. The scaffold is always precisely constructed by the dental technician according to the specifications of a denture impression with an impressive mass or a mouth scan on the computer.
Precise coloring to match the teeth of the patient
When the core is finished, the veneer is fired. To do this, the dental technician applies several ceramic materials to the framework and burns each one in a special ceramic oven.
In this way, natural tooth colors and color gradients are created according to the wishes and specifications of the dentist. Different colors, for example on the tooth necks, can also be realized by this stoving technique.
A Zirkonkrone thus divided after insertion completely natural in the existing teeth. It therefore not only restores the functionality of the tooth but can also visually convince.
The Right Care Of The Zirconium Crown
Zircon as tooth replacement material has the great advantage that it is very resistant to bacteria, as they can hardly be deposited on the surface. Basically, the zirconium crown is brushed with the daily brushing teeth as normal. It is always cemented firmly on the still existing tooth stump of the patient.
