Nowadays, zirconia all ceramic teeth have been favored by thousands of people. This kind of high-quality ceramic material will become the trend of dental cosmetic repair in the future. It is reported that the price of Peking University Dental Hospital has been comprehensively re priced, with 8000 cases of zirconia all ceramic.


Now, let's take you to know about zirconia all ceramic teeth




Zirconia all ceramic teeth is a high-tech method of cosmetic restoration of teeth developed in recent years. It is made by computer-aided design, laser scanning, and then grinding by computer program control.



A small amount of medical zirconia remains in zirconium after cleaning α The residual ray penetration depth is very small, only 60 microns. The density and strength of zirconia all ceramic teeth are quite high, which is 1.5 times higher than the second generation of press, and more than 60% higher than inceram zirconia. In addition to its unique fracture resistance and strong and tough curing performance after fracture, it can make more than 6 units of all ceramic bridges, which solves the problem that all ceramic systems cannot be used as long bridges.



The color of zirconia all ceramic teeth is extremely natural, and the edge of the crown is not obvious, especially for patients who have high aesthetic requirements and pay attention to its natural color, it is the best way of tooth beauty. Zirconia all ceramic teeth integrate the restoration with healthy teeth, which is difficult to distinguish.


Do you know? If the denture embedded in your mouth is an all ceramic crown containing metal, it will be affected or even removed when you need to have a head X-ray, CT, MRI examination. Non metallic zirconium dioxide has no barrier to X-ray. As long as zirconium dioxide all ceramic teeth are inserted, there is no need to remove false teeth when skull X-ray, CT, nuclear magnetic resonance examination is required in the future, which saves a lot of trouble.




Zirconia is an excellent high-tech biomaterial with good biocompatibility, which is superior to all kinds of metal alloys, including gold. Zirconia has no irritation and allergic reaction to gums, which is very suitable for oral application, and avoids the allergy, irritation, corrosion and other adverse reactions caused by metal in the oral cavity.



Compared with other all ceramic restorative materials, zirconia all ceramic dental materials have the strength advantage that doctors can achieve extremely high strength without too much grinding of patients' real teeth. Among them, Vita all ceramic plus yttrium stabilized zirconia is known as ceramic steel.



Zirconia all ceramic teeth have very high quality. It is said that its high quality is not only because its materials and equipment are expensive, but also because it is made by using the most advanced computer-aided design, laser scanning, and then grinding by computer program control, which is perfect.



Zirconia all ceramic teeth PK metal all ceramic teeth


1、 Metal all ceramic teeth


Metal all ceramic crown is accepted by most patients because of its good strength, but it has its fatal shortcomings. The metal base of metal all ceramic teeth is easy to oxidize to form gray oxide, which is scattered and deposited on the edge of the gums, causing the gums to become gray and affecting the appearance. At the same time, it has a strong stimulating effect on the gums. Some patients will also have symptoms such as gum swelling, bleeding, allergy and so on, which is difficult to meet the clinical requirements.


Due to the existence of metal base crowns, the color of all ceramic crowns must be covered with opaque porcelain, so that all ceramic crowns can have a certain degree of radiation blocking effect on light, which seriously affects the beauty of teeth.


2、 Zirconia for all ceramic teeth


At present, there are many kinds of all ceramic dental materials, such as leucite, lithium based ceramics, alumina, zirconia, etc., and the manufacturing methods are different, such as infiltrated ceramics, hot pressed cast ceramics, ceramic deposition, computer-aided design and computer-aided manufacturing. However, in comparison, among all ceramic restoration materials, zirconia all ceramic has the highest bending strength, so it is accepted by more and more patients and doctors, and is welcomed by the world.


Zirconia all ceramic crown has its own unique advantages. Because there is no metal bottom crown, its restoration has certain permeability and aesthetics, so it provides a guarantee for aesthetic restoration. At the same time, it has no irritating effect on the gums, and the patients will not have gum swelling, bleeding, allergy and other symptoms. It perfectly meets the clinical requirements, so it is called the "new favorite" of all ceramic teeth.


Zirconia all ceramic crowns have unique advantages that metal all ceramic teeth do not have:


1. Excellent mechanical properties.


It has a bending strength greater than 900MPa, so it can also be used for posterior teeth and all ceramic bridges with more than 6 units.


2. Good biocompatibility.


According to the latest CRAI clinical evaluation report of the American Association for clinical research, zirconia all ceramic crowns are metal free, and the restoration of zirconia all ceramic crowns can eliminate metal allergy. At the same time, it has good biocompatibility, so it is superior to all kinds of metal alloys, including gold materials.


3. Zirconia has no barrier to X-ray.


After inserting zirconia all ceramic teeth, if it is necessary to carry out cranial X-ray, CT and nuclear magnetic resonance examination in the future, it is not necessary to remove the false teeth, because zirconia all ceramic teeth do not block the X-ray, so a lot of trouble is saved.


4. Non metallic materials are safer


Zirconia is currently the only mineral in nature that exists as oblique zircon. It does not contain metal components, and it is safer after cleaning and processing of medical zirconia.


5. Ultra high strength and density


Zirconia is widely used, especially in high-precision instruments, such as aviation equipment, because of its ultra-high strength and density. Among them, the unique fracture resistance and strong curing after fracture can be made into all ceramic bridges with more than 6 units, which solves the problem that all all ceramic systems cannot be used as long bridges, so it is loved by doctors and patients.


6. Perfect color


Because the color of the base crown of structural ceramics is white, the neck will not turn black and dark for a period of time after the all ceramic teeth are inserted, which solves the extremely difficult problem of metal all ceramic crowns.


7. Healthy biomaterials


Zirconia is an excellent high-tech biomaterial, which has excellent biocompatibility, no irritation to gums, no allergic reaction, and is very suitable for oral cavity.


8. High tech quality


Zirconia all ceramic teeth are made by using the world's most advanced computer-aided design, laser scanning, and finally grinding by computer-aided program control, showing noble and luxurious quality.
