The trend of development of modern dentistry is aimed at the development of nonmetallic technologies. For many years, orthopedic dentistry is in search of an ideal material that does not contain metal. The technical capabilities of traditional laboratory equipment for processing more stable materials are limited. And only with the advent of computer-controlled machines it was possible to expand the boundaries of accuracy and stability known at that time. In the process of searching for more stable materials, zirconium oxide attracted attention. Outstanding properties, such as high strength (900 to 1200 mPa) and almost 2 times higher fracture toughness compared to aluminum oxide, make zirconium oxide in demand in areas where high stability is required for a long time under high loads. It is biocompatible material and is increasingly used in medicine (hearing, orthopedics) and dentistry (pins, crowns, implants). In the industry, zirconium has been used for more than forty years.
Zirconium - one of the old and common minerals of the earth's crust. From this chemical element, zirconium dioxide is produced - a high-tech material that is used in medicine. Now there is an opportunity to apply this material in dentistry. Among the dental ceramics available today, zirconium dioxide with its biocompatibility properties clearly demonstrates the good characteristics required for the manufacture of modern dentures.
Advantages of dentures based on zirconia:
- High light transmission;
- Technique of individual recreation of the color of the patient's teeth;
- Absence of a dark border;
- Complete absence of metal;
- Excellent biocompatibility;
- High strength;
Optical identity to natural teeth, durability and convenience in use, whether the crown or bridge of zirconium dioxide meets the high requirements for the quality and durability of the denture. Teeth after the procedure of prosthetics get a healthy and well-groomed appearance.
