Zirconia-Based Crowns and Bridges
Zirconia dental crowns are used on severely damaged or previously prepared teeth to improve their appearance and health. We do not prepare any teeth for this procedure that have not already been reduced for a previous crown. Preserving the healthy tissue of the teeth should be one of the most important principles of dentistry, based on current knowledge.
In this system, zirconium a white alloy is used as the substructure instead of metal. This state-of-the-art substructure is the only material capable of combining aesthetics with durability. The system’s greatest advantage is that it achieves very high durability while also providing a fully aesthetic appearance for bridges in the posterior region.
For many years, a metal substructure has been used under porcelain crowns to ensure durability. Since the drawbacks of this metal substructure regarding the gums, dental tissue, overall health, and, most importantly, aesthetics are well known, the search for an alternative material to metal in porcelain restorations has been ongoing for years.
The use of zirconium which had previously been successfully employed in other fields of medicine as a replacement for porcelain-fused-to-metal restorations in dentistry has ushered in a new era. This is because these new zirconium-based porcelain crowns not only prevent gum problems and allergic reactions but also, thanks to their light-transmitting properties, allow us to achieve aesthetics and function that closely resemble those of natural teeth.
Today, efforts are being made to modify the structure of zirconia to make it more translucent and give it a more natural appearance. The results have been quite successful and satisfying. Zirconia materials with superior properties, produced by various manufacturers, are changing the perception that existing options are aesthetically inadequate.
