Anonymous users2024-02-05Although cobalt-chrome porcelain teeth have become the first choice for dental restoration, not all cases can be applied to cobalt-chrome porcelain teeth. The scope of application of cobalt-chrome porcelain teeth is as follows:
1.Tooth restoration: After the tooth has been determined to have no possibility of inflammation and pain, the cobalt chrome porcelain tooth can be used for tooth restoration to avoid tooth discoloration and tooth cracking.
2.After the tooth is extracted, it is necessary to make dentures for tooth filling, at this time, you can choose to use cobalt-chrome porcelain teeth, and fix the cobalt-chrome porcelain teeth on the healthy teeth next to them, which will not affect normal chewing and diet.
3.Many people are born with dental deformities, such as crooked teeth, small or large teeth, which can be repaired with cobalt-chrome porcelain teeth. After restoration, it is possible to ensure that the full mouth of teeth is in ideal condition.
4.If the tooth has been discolored, oxidized, or the pulp is dead, and other methods can no longer be used to restore it, you can choose to use cobalt-chrome porcelain tooth restoration.

Anonymous users2024-02-04Same. Cobalt-chromium biological porcelain teeth should be cobalt-chromium alloy porcelain teeth. The word "creature" is redundant and purely fancy. If it is an all-ceramic tooth, it will not be called a cobalt-chromium bio-porcelain tooth.
Cobalt-chrome alloy porcelain teeth were developed for the toxicity of nickel and beryllium, and began to be called "nickel-free beryllium-free alloys". Because it does not contain nickel and beryllium, cobalt-chromium alloys have good biocompatibility, and were first used in orthopedic transplant medicine, and are widely used to make artificial joints, which have been used to this day. It can be said that cobalt-chromium alloy is a good biometal.
Advantages of cobalt-chromium alloy porcelain teeth: compared with nickel-chromium alloy, its cobalt content is higher, generally 25, because of the high cobalt content, so its corrosion resistance is better than that of nickel-chromium alloy, the metal stability is better, the probability of gingival black lines is much smaller, and the combination with porcelain is better, and it is more difficult to break porcelain. Another advantage of cobalt-chrome alloy is that it has a higher hardness than gold alloy (**), which is not easy to deform when used to make longer porcelain bridges.
**The strength of the metal base of the porcelain tooth is not enough, and it is easy to collapse when the porcelain bridge is long and the bridge body is deformed greatly. When there are many missing teeth and the porcelain bridge is longer, it is more suitable to use cobalt-chrome alloy. Cobalt-chromium alloy does not contain nickel and beryllium and other elements that are toxic to the human body, safe and reliable, reasonable, and can be said to be the most cost-effective base metal porcelain alloy, but its performance is still far behind the best and all-porcelain.

Its advantages are that it has strong metal stability, high corrosion resistance, and generally does not appear black gums or bleeding gums. Compared with porcelain teeth and all-ceramic teeth, the cost of cobalt-chromium porcelain teeth is significantly lower.
Compared with nickel-chromium porcelain teeth, cobalt-chromium porcelain teeth are safer. It is a typical non-*** porcelain tooth. Porcelain tooth is a relatively advanced dental prosthesis technology.
It has the advantages of beauty, naturalness, firmness, wear resistance, etc., and is a favorite product for many dental patients. So what are the components of cobalt-chromium porcelain teeth? Generally, chromium is not less than 25%, molybdenum is not less than 4%, and cobalt, nickel, and chromium add up to not less than 85%.
The quality of cobalt-chrome alloy porcelain teeth is currently a matter of opinion. One person believes that nickel-chromium porcelain teeth** are cheaper and are commonly used, and more than 50% of patients with porcelain teeth choose this type of porcelain teeth. Good biointegration, beauty, economy, durability and other advantages.
However, some people are confirmed to have poor biointegration of this kind of porcelain teeth, which is easy to cause allergies in some people, resulting in inflammation of the mucous membrane. The specific use of porcelain teeth should be decided after consultation with the attending doctor of the regular hospital. In the world, the selection and use of non-*** alloys is not the same.
The United States uses more nickel-chromium alloys; In Europe and Japan, cobalt-chromium alloys are basically used for fixed repairs, and nickel content above 1% is usually unusable. Nichrome is easier to cast and more economical than cobalt-chrome alloys, but its physical properties and corrosion resistance are not as good as cobalt-chromium alloys. When exposed to a thermal environment, such as in porcelain, the physical properties of the nichrome alloy may change, making the alloy more fragile and unsuitable for use as a long bridge.
In this regard, cobalt-chromium alloys are far superior to nickel-chromium alloys in terms of resistance to heat treatment (Morris 1990, Sing et al.). 1999)。Now let's get a little bit of an idea.
Cobalt-chrome alloy porcelain teeth** How much is an affordable porcelain tooth.
Precautions for porcelain teeth: 1. Patients with mild discomfort when wearing porcelain teeth for the first time should practice patiently and gradually adapt. 2. Eat soft food when you first wear it, and then eat normal food after adaptation. >>>More
Your ** is a bit cheap, not very believable, but porcelain teeth generally need to make a small amount of adjustment, the so-called micro adjustment means that the porcelain teeth may be a little high after the local is done, the adjacent surface is a little tight, these situations are allowed, because the porcelain teeth are done on the model, there will be a certain deformation after a few mold turns, but this coefficient is very small, that is, as long as the adjustment is a little bit, and it is to adjust the porcelain teeth, and then adjust the teeth that is the doctor's shortcomings, technical problems, As for the impact of nickel-cadmium alloy on the kidneys, we generally do not recommend doing it, because the material is poor, and the biocompatibility is not good, we generally recommend at least cobalt-chromium alloy, if you have the ability, the best all-ceramic teeth, *** almost nothing, the teeth must be done after grinding, no way, there is another problem, that is, after you do the root canal, it is generally recommended that it is best to make a pile and then do braces, which can prevent the crown from breaking, the root remains, and the porcelain falls off. Do it in time, otherwise the teeth will be displaced
The difference between porcelain teeth and all-porcelain teeth is that the all-porcelain teeth are transparent in appearance and more like real teeth, which is a difficult task for porcelain teeth. The metal crown of the porcelain tooth crown is opaque, and opaque color-shielding porcelain needs to be used to shade the metal, which affects the transparency of the restoration, so that the porcelain tooth has obvious chalkiness, paleness, and falsehood after cosmetic treatment, and there are more "black lines" caused by the metal substrate on the neck of the tooth, which affects the appearance. All-ceramic teeth have good transparency and shading, and the high-strength inner crown solves this cosmetic stubbornness, resulting in a good aesthetic effect on the neck of the tooth. >>>More
The agreement will not be signed by the general hospital Oh porcelain tooth processing plant is a year package (quality problem) hospital will not manage another point After doing porcelain tooth, the hospital should be able to give you a warranty card Porcelain is generally not done by the external processing hospital itself >>>More
There is no specific unity of porcelain teeth, which has a lot to do with the material, and the quality of the material is directly related to the level of the material, as well as the factors that will affect the equipment of the dental hospital and the technology of the doctor, etc., as well as the patient's own oral condition. It is recommended that porcelain tooth restoration needs to go to a professional dental hospital to rest assured. >>>More
