Zirconium dioxide is a mineral that exists in nature as plagioclase zirconia, an inorganic non-metallic material that is resistant to high temperatures, wear and corrosion. It has a melting point of up to 2,700 degrees Celsius. Zirconium dioxide is has been proven successful for use in thermal barriers on the Space Shuttle, brake discs on Porsche cars, and artificial transmission belts, zirconium dioxide is far stronger than all other all-ceramic teeth. Today’s zirconium dioxide all-ceramic teeth are made using computerized CAD-CAM technology, which means laser scanning, computer-aided design, and machining of a suitable crown, or bridge as it’s called, on a three-dimensional, numerically-controlled, specialized machine tool. The zirconium dioxide all-ceramic teeth made by this method have extremely high tightness. It is recognized as the first choice for “beautiful teeth” by domestic and foreign aestheticians. Zirconium dioxide all-ceramic/all-zirconium dental crowns have the following advantages: 1, high strength, high density, no metal inner crown. Unique rupture resistance and strong curing performance after rupture, can make more than 6 units of porcelain bridge, solved all the all-ceramic system can not do long bridge problem. 2, the crown is not supported by metal, but has high strength, refractive index is basically close to the natural teeth, the edge of the dense and high precision, with excellent aesthetic effect, the only disadvantage is expensive. In addition, the current all-ceramic technology can only produce a single crown and three units of the bridge, if there are more missing teeth, it is not suitable for all-ceramic technology repair. Nowadays, zirconium dioxide computerized all-ceramic technology has been popular in the United States and European countries, which has brought the best treatment effect for the majority of tetracycline teeth patients. 3, zirconium dioxide is an excellent high-tech biological material. Good biocompatibility, superior to various metal alloys, including gold. Zirconium dioxide has no irritation and allergic reaction to the gums, which is very suitable for application in the oral cavity and avoids allergy, irritation, corrosion and other undesirable stimuli produced by metal in the oral cavity. Unique rupture resistance and strong curing properties after rupture. 4, the natural feel of the tooth color and inconspicuous crown margins are also benefits brought about by the use of zirconium dioxide all-ceramic restoration. In particular, patients with high aesthetic requirements pay more attention to the advantage of its natural color, because this makes the restoration and healthy teeth are one and the same, it is difficult to distinguish. 5, MRI examination, non-metallic zirconium dioxide on the x-ray without any obstruction, MRI examination do not need to remove the denture, save a lot of trouble, convenient MRI examination is also one of its characteristics. 6, zirconium dioxide porcelain teeth have very high quality, said its high quality not only because of its materials, expensive equipment, but also because of its use of today’s most advanced computer-aided design, laser scanning, and then by the computer program control grinding and production, perfect. 7, zirconium dioxide material and other all-ceramic restoration materials compared to its strength advantages so that the doctor does not have to excessive grinding of the patient’s real teeth, you can achieve a very high strength. Having a mouthful of neat, white and beautiful teeth is one of the top ten health symbols of modern people. Porcelain has long been a fast, effective way to restore discolored and decayed teeth. However, the metal ions within the metal porcelain will produce adverse reactions to the human body, such as blackening of the gums, bleeding gums, shrinkage; and should be the existence of its metal crown, light transmission, color and form and natural teeth there are big differences, more will be in the light to produce the effect of “greenish gray”, all-ceramic / zirconium crowns can completely overcome all the shortcomings of the metal porcelain crowns, it will be your healthy and beautiful teeth. All-ceramic/all-zirconia crowns can completely overcome all the shortcomings of metal porcelain crowns, which will be the best choice for your health and beauty!
