1. Ordinary porcelain tooth (nickel-chromium alloy porcelain tooth)
Relatively inexpensive, the lowest-end porcelain tooth will release metal ions in the oral saliva environment 3-5 years after restoration, which is harmful to the health of the whole body. In the restoration of anterior teeth, there are aesthetic problems with the nichrome porcelain material.
2. 3D porcelain teeth
The color control of 3D porcelain is better than that of 95 porcelain.
3. Titanium alloy porcelain teeth
Titanium metal can change the properties of the alloy, reduce the precipitation of nickel, the titanium content is only 4-6%, and titanium is volatile in the casting process, and there is no obvious change to the problems such as gum blackening.
4. Gold-plated porcelain teeth
After the nickel-chromium alloy porcelain tooth is done, a layer of gold is plated on the exposed metal, which can achieve the protective effect of preventing the precipitation of nickel ions, and the gold layer is very thin, after the long-term use of the porcelain teeth, it is difficult to ensure that the gold plated on the exposed metal is not worn off, therefore, the problem of nickel ion pollution to the body and the problem of gum coloring can not be effectively avoided for a long time.
5. Shoulder porcelain non-precious alloy porcelain teeth
The free porcelain tooth neck shoulder is all made of porcelain to avoid the problem of gum coloration, and the color of the neck close to the gums is more layered and more realistic. To a large extent, to prevent the release of nickel ions, the staining of the gums is brittle, even if it is simple grinding, it may cause porcelain collapse, or if there is not enough resistance type of shoulder table, it will also be easy to cause porcelain collapse in the process of use.
6. Cobalt-chrome alloy porcelain teeth
It does not contain nickel beryllium and other toxic substances to the human body, has good biocompatibility, has little irritation to the gums, and is not prone to the problem of black lines of the gums.
7. P.F. Titanium
It is light in weight (compared with the full mouth of gold teeth), has no effect on MRI, and is more suitable for elderly patients, where the processing of pure titanium is difficult and the probability of porcelain collapse is high.
8. Ordinary all-porcelain tooth (alumina all-porcelain)
The glass of the German company VITE penetrates all porcelain. The transparency of alumina material is lower than that of cast porcelain, and the strength is slightly higher than that of cast porcelain, and it is necessary to have a complete shoulder preparation and a high-precision model to ensure the sealing of the teeth and obtain sufficient strength to prevent porcelain breaking.
9. Gold deposition porcelain teeth
The gold content is 99.99%, the edge is well sealed, which can prevent the occurrence of secondary caries, the irritation to the gums is slight, the plaque attachment is less, and the gingival discoloration caused by the material and the crown edge is not fitted.
10. CAPTEK
Similar to gold deposition porcelain teeth, the inner crown is hand-kneaded, with a gold content of 89%, and the combination effect and strength of porcelain powder are higher than those of gold deposition porcelain. It has no irritation to the gums and is ideal for periodontal patients.
11. Precious metal porcelain teeth
The gold content is 87.7%, which has little irritation to the gums and can be used as a bridge. There are also several other types of gold porcelain teeth with different gold contents, and the price varies according to the gold content.
12. Cast porcelain
Transparency is the best of all all-ceramic materials.
13. Zekang all-porcelain
It can make a 38 mm bridge for the back teeth, the strength is very high and cannot be used with the back teeth, the bridge body of the front teeth can be made with three units, and the crown color is dark or the metal pile core is not suitable for cast porcelain restoration.
14. Kava all-porcelain
The posterior bridge body can be made with higher strength, and the inner crown color can be selected, making the whole tooth color more natural and realistic.
