If you have metal porcelain teeth in your mouth and you do MRI and CT, the images are radial with the porcelain teeth as the center. The surrounding tissues cannot be seen clearly, which affects the clinical diagnosis. It is recommended that friends who have the conditions should choose zirconium dioxide all-ceramic crowns to repair them, so as to avoid unnecessary trouble! And today, we will further explore zirconia ceramic crowns<\/a> for dental restorations.<\/p>\n\n\n\n

What Is a Zirconium Dioxide All-Ceramic Crown?<\/h3>\n\n\n\n

Zirconia (i.e. zirconium dioxide) all-ceramic teeth are a type of all-ceramic porcelain teeth. Because its internal structure material is zirconium oxide ceramic, it is called zirconium oxide all-ceramic teeth.<\/p>\n\n\n\n

Zirconia ceramic crowns are the strongest kind of tooth restoration, so it is not easy to break when used to repair teeth. Secondly, it can be used for beauty and repair of missing teeth. It can repair multiple teeth, that is, it can be used for continuous crown tooth restoration.<\/p>\n\n\n\n

At present, zirconia ceramic teeth are made by computer CAD-CAM technology, that is, laser scanning, computer-aided design, and three-dimensional CNC professional machine tools to process suitable crowns or bridges.<\/p>\n\n\n\n

Advantages of zirconia ceramic crowns<\/h3>\n\n\n\n

1. Low radiation<\/strong>
Zirconia is a mineral that exists in nature as baddeleyite. Medical zirconium oxide is cleaned and processed, and the small amount of alpha ray residues retained in zirconium have a very small penetration depth of only 60 microns.<\/p>\n\n\n\n

2. High density, high strength, and no metal inner crown<\/strong>
The unique fracture resistance and strong curing performance after fracture can make porcelain bridges of more than 6 units, solving the problem that all ceramic systems cannot make long bridges. Although there is no metal support, it has high strength, the refractive index is basically close to that of natural teeth, the edge is dense and precise, and it has excellent aesthetic effects.<\/p>\n\n\n\n

3. Excellent aesthetic effect<\/strong>
Successful ceramic tooth restoration has a realistic and beautiful appearance, is strong and wear-resistant, has a color similar to natural teeth, has good biocompatibility, does not irritate oral tissue, is easy to clean, and can not only restore the function of teeth but also has a cosmetic effect. The most important thing is that zirconia ceramic teeth have good transparency and refractive properties, and no black lines will appear on the neck of the teeth, so the neck of the teeth can also achieve a good aesthetic effect, which is unmatched by ordinary porcelain teeth.<\/p>\n\n\n\n

4. Strongest reliability<\/strong>
No metallic odor, it will quickly produce a micro-oxide film when it comes into contact with air, water or any other electrolyte, which not only avoids metal corrosion but also prevents the generation of metallic odor.
In addition, non-metallic zirconium dioxide has no obstruction to X-rays. As long as zirconium dioxide porcelain teeth are inserted, there is no need to remove the dentures for future head X-rays, CT scans, and MRI examinations, saving a lot of trouble.<\/p>\n\n\n\n

5. Good biocompatibility<\/strong>
Zirconium dioxide is an excellent high-tech biomaterial with good biocompatibility, which is superior to various metal alloys, including gold. Zirconium dioxide has no irritation to the gums and no allergic reaction, which is very suitable for use in the oral cavity, avoiding adverse reactions such as allergies, irritation, and corrosion caused by metal in the oral cavity.<\/p>\n\n\n\n

Why does the dentist ask you to make zirconia ceramic crowns?<\/h3>\n\n\n\n

The disadvantages of ordinary porcelain teeth (nickel-chromium alloy porcelain teeth) are as follows:<\/p>\n\n\n\n

1. Metal ions will be released in the oral saliva environment 3-5 years after restoration, and metal ions will have adverse reactions to the human body, such as black gums, bleeding and atrophy of gums, etc.<\/p>\n\n\n\n

2. Due to the presence of metal inner crowns, the light transmittance, color and shape are quite different from natural teeth, and will produce a blue-gray effect under the light. At the same time, metal porcelain teeth are unstable under the action of bacteria in the liquid oral acid-base environment, and the metal has a certain dryness when the patient undergoes CT nuclear magnetic resonance.<\/p>\n\n\n\n

3. In the restoration of anterior teeth, nickel-chromium alloy porcelain materials have aesthetic problems.<\/p>\n\n\n\n

Zirconium oxide all-ceramic crowns do not have any of the above problems.<\/strong><\/p>\n\n\n\n

Conclusione<\/h3>\n\n\n\n

Zirconia ceramic teeth can be used for beauty and restoration of missing teeth, and can repair multiple teeth. It is a design that emphasizes holistic thinking, so the teeth made are realistic in shape. Its color is natural and realistic, and it looks very similar to real teeth. Zirconia ceramic teeth have excellent biocompatibility, so using it to repair teeth will not cause gingivitis.<\/p>\n\n\n\n
