Zirconia metal-free ceramic is used in cases where it is necessary to restore the functionality of the dentition and get rid of the aesthetic defect.

Prosthetics with zirconia-based structures is one of the latest advances in dentistry.

Zirconia ceramic dental prostheses are lightweight, reliable and aesthetic designs.

Features

• The material is harmless to the body.
• It has no negative effect on the gum tissue.
• Hypoallergenic material, a high degree of biocompatibility with the tissues of the tooth and gums.
• Metal-free ceramic designs are indistinguishable from real teeth. Often, even a specialist cannot distinguish them.
• The material is used to eliminate any problems of the dentition (chips, cracks, discoloration of the enamel).

Advantages

• Excellent aesthetics of designs.
• The longevity of dentures.
• High degree of resemblance to natural teeth.
• The possibility of prosthetics for people with allergies.
• Automation of the manufacturing process of crowns and veneers.
• No negative effect of the material on the gum tissue.
• High accuracy of edge fit of structures.
• The presence of a smooth tooth surface prevents plaque formation on its surface.
• Resistance to acid.
• The presence of high thermal insulation properties allow you to consume foods and drinks of various temperatures.

How to make

Computer simulation is carried out using a special program that provides high accuracy of the process.

• The structures are based on a solid frame, which is made by pressing and firing ceramics.
• On a gypsum model of a patient’s teeth, a waxing technician reproduces the shape of a future design using wax.
• Pressing a ceramic block structure at high temperature in a special furnace.
• Ceramic coating of the crown and firing.

As a result, the finished design completely repeats the shape and color of the native tooth.

Today, the use of CAD / CAM technologies is one of the most advanced methods for the manufacture of ceramic structures made of zirconia.

By observing the technology of manufacturing the prosthesis, excellent esthetics and a long term of use can be achieved.

Problems arise when the manufacturing technology of the structure is violated. The occurrence of problems is also possible with poor-quality preparation of the tooth for prosthetics.

Reviews on Zirconia Metal-Free Ceramics

• My teeth have been affected by caries since childhood.Constantly had to put seals. As a result, the teeth collapsed almost completely, and the dentist suggested that crowns be prosthetized in order to somehow preserve what was left of the teeth. I installed metal-free zirconia ceramics on two teeth in front, and metal-ceramic crowns on chewing teeth. When the crowns were installed, the teeth were grinded so that almost nothing was left of them. It was also very unpleasant when, when turning, the gum was pushed back and a special thread was laid. As a result, I do not regret that I chose a zirconia crown for prosthetics of the front teeth. I quickly got used to prostheses, they stand like relatives and their color does not differ at all from my real teeth.
• Zirconium veneers have been standing on my front teeth for a year now. I had to put the plates due to the fact that the teeth were very erased. I faced a choice: pads, or crowns. I chose veneers because I didn’t want to sharpen my teeth. And when preparing the teeth under the plate, very little enamel was removed and only on the front side. The appearance of new teeth is much better than real ones. I do not feel any discomfort when chewing.
• He placed zirconium prostheses on the front upper teeth two years ago. Crowns were made using modern CAD / CAM technology. Dentures were installed quickly enough. Before turning my teeth, they anesthetized, and then temporary dental crowns were fixed, with which I went for several days. After installing permanent zirconia crowns, I got used to them very quickly. Discomfort during getting used to prostheses was minimal. Very pleased with my new teeth. Friends and acquaintances do not notice at all that my teeth are not real.
• By the age of 28, my front two teeth after constant fillings began to slowly break off and I had to think about prosthetics with crowns. I really did not want to install metal-ceramic, because according to my observations on the teeth of other people, they were noticeable. In the dental clinic, the doctor said that now there are more modern technologies for prosthetics and proposed crowns on zirconium dioxide. Before starting the prosthetics, the dentist took pictures, treated and sealed the canals. It took about a week to treat the teeth. Then they turned the teeth and set temporary crowns at the time of manufacture of the permanent ones. After a couple of days, the crowns were ready. After fixing the zirconium crowns on my teeth, I almost shed a tear. Finally, I have beautiful teeth and I can not hide a smile from others. The teeth are alive and have the natural color of my teeth. I have been using prostheses for more than a year, the color has not changed at all, I follow all the requirements for the use of ceramic structures made of zirconium.
• My mother placed four zirconium crowns on her upper jaw teeth. Before the prosthetics, the oral cavity was sanitized and four teeth were turned under the dentures. After the teeth were grinded, they put on temporary plastic crowns, with which she had to walk for about two weeks. A few days after turning, my mother constantly used painkillers because her teeth ached all the time. During this time, permanent crowns were made from non-metal ceramics on zirconium oxide. After the finished crowns were installed, the mother still cannot stop looking at them. The dentist promised. What can she use them for about fifteen years or more.
