Why choose zirconia-based dental crowns?
Zirconia is the most resilient material used in dentistry. However, strength is not the single quality that recommends zirconia for the reconstruction of one or more teeth. This material also offers a flawless aesthetic aspect, being the most endorsed material for simple dental crowns, extended bridges or dental implant constructions.
For denture constructions, we do not use pure zirconia, but a chemical combination – zirconium oxide. Computerized milling processes zirconium oxide, resulting in extremely precise prosthetic parts, both functionally, and aesthetically.
When you have to choose the ideal material for restoring your denture, the decision may be pretty difficult. The large range of materials may make it difficult for you, although your physician may be very clear on the advantages and disadvantages of each of them.
In order to choose the material for the restoration of your denture, you should think about what’s really important for you, from the following considerations:
Aesthetic aspect: Zirconia-based crowns have the advantage of being translucent. Therefore, they reflect white colour like a natural tooth. More, unlike metal ceramic crowns, in which case we can notice the grey line from the bottom of the gum, the zirconia-based crowns are perfect, both with regards to their application, and to the precise construction.
Teeth reconstructed with zirconia-based crowns are identical to your natural teeth, such works being ideal especially for the front part of your denture.
Comfort: Zirconia is a biocompatible material (just like gold). It can be used even in the case of allergies to metal and it is quickly integrated in the dental structures and in the gum. Due to its low weight, zirconia-based crowns do not create discomfort, irrespective of the area the denture is placed.
Strength: The zirconia-based crowns are obtained by computerized modern technique, which makes them extremely precise. They resolve successfully the issue of functionality (diction, mastication) and resist in time due to the specific resistance of this material. As compared to the metal-ceramic, metal-acrylic prosthesis constructions, the zirconia-based crowns are much more resistant.
Procedure: In order to place a zirconia-based crown, in case of a tooth reconstruction, we remove the minimum osseous tissue. The intervention is not that complex, like in case of metal-ceramic works, and there is no risk of chemical reactions, as zirconium has no allergen potential.
The only disadvantage in case of zirconium is, without any shadow of a doubt, the price of the dental crown. As it is an expensive material needing special processing, zirconium has a cost that may be considered expensive.
Therefore, when aesthetics, functionality, time resistance of your smile and comfort are of utmost importance to you, zirconium should become your first choice, either in the case of covering a dental implant or a tooth.
