Anonymous users2024-02-06If the porcelain tooth is made of chemically inert metal, because of its chemical instability, the metal ions are easy to be freed out and deposited in the gums or tooth root hard tissues adjacent to the porcelain teeth, making the gums at the contact site black. This is the main cause of darkening of the gums when porcelain teeth are made. In addition, if the doctors and technicians are not in place, the edges of the porcelain teeth are not suitable, they are located on the gums or do not fit well with the natural teeth, and there is a gap between the natural teeth and the natural teeth after being worn on them, and then the porcelain teeth will have a series of problems, including the black line of the gums.
Choosing a regular hospital for all-ceramic teeth generally does not have black lines on the gums. I wish you good dental health and all your dental services for you!

Anonymous users2024-02-05You can come to our hospital for consultation, and it is recommended to choose a mid-range cobalt-chrome porcelain crown. Cobalt-chrome alloy porcelain crown (tooth), its full name is cobalt-chrome alloy stainless steel inner crown metal melting cast porcelain crown. If you say the full name, you can actually know its essence, high-quality cobalt-chrome porcelain crown is mainly the choice of steel, porcelain powder (porcelain powder has been very unified, monopolized by foreign brands) cautery technology, the doctor's preparation level, your region, the decoration of the treatment and the level of the hospital.
The cost of cobalt-chrome porcelain crowns in first-tier cities ranges from 800-1500. There is no possibility of dark gums. The price difference is mainly due to the level of the hospital, geographical location, and operating costs.
If you can't determine the doctor's level of meticulousness, it is generally judged from the doctor's handwriting, the thoroughness of the theory, and the preparation time of a tooth (about 30 minutes for a front tooth and 40-50 minutes for a back tooth).

Anonymous users2024-02-03With the continuous improvement of everyone's living standards, people's awareness of the health care of their teeth is also constantly improving and attaching importance to it, so dental beauty projects are becoming more and more popular. However, many people find that the real teeth inside the porcelain teeth have turned black after doing porcelain teeth, what is going on? Let's take a look.
1. Physician technology
This phenomenon of blackening of porcelain teeth has nothing to do with the material, but is due to the lack of skill of the physician to cause the edges of the porcelain teeth to be unsuitable. If it is located above the gums or does not fit well with the natural teeth, there is a gap between the porcelain teeth and the natural teeth, and then a series of problems such as the black line of the gums will appear.
2. Porcelain tooth material
Due to the unstable chemical properties of the metal, the porcelain tooth with the base metal crown will continue to release some ions, and people with sensitive constitution are not only prone to allergic reactions, but also prone to adverse reactions such as redness, swelling and bleeding of nucleoid gums. At the same time, a large number of ions are deposited in the hard tissue of the gums or tooth roots, which can also cause the gums to darken.
3. The internal structure of porcelain teeth
The enamel of the natural tooth and the dentin of the inner layer have a certain degree of light transmittance, because the metal layer inside the porcelain tooth is opaque, the light can not reach the neck of the porcelain tooth when it is refracted inside, so the contact between the porcelain tooth and the gum is darker than other parts. This blackening is common to all metal porcelain teeth.
4. The preparation is unqualified
Because the preparation of porcelain teeth is unqualified, porcelain teeth and real teeth are not close enough, including *** porcelain teeth (** chain wild porcelain teeth), no matter what kind of metal is used, there may be black lines on the gums.
The above is the content of the black of the real teeth in the porcelain teeth. In short, although porcelain teeth are very good and play a very good role in our dental restoration, before you choose to do porcelain teeth, you should go to a professional dental hospital or clinic with a high level of production and a high level of doctors to implant porcelain teeth, so as to ensure the quality of the implanted porcelain teeth.

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
