We usually think that the only function of our teeth is to cut and crush food. Hence, Artificial teeth The fact that people who have lost their natural works are usually implanted: to process food. However, our teeth are much more than it. They act as a connection between our mouth and nerves that carry information to the brain so that we can know, very cold food or if It burns too much to continue to eatThey also intervene in the field. We all saw how people say who have no teeth. But in order for all this to be done correctly, it is necessary that the teeth unite with the nerves on the other side of the elastic band, and that, unfortunately, this is what has not yet been achieved using artificial teeth.
The positive part of this story lies in the fact that he will soon have a solution thanks to artificial teeth developed by the team of scientists from University of Tafts. Usually prostheses are associated with the bone of the jaw through some Special screwsThe nerves are not taken into account.
However, their artificial teeth grow directly on the elastic band and a little They are connected to the nerves Maintain this communication with the brain, which is usually lost when the loss of natural dental pieces. This is a great advance that now He was tested alone at the mice. But with them the results were pretty good. Everything is almost ready to start preparing an essay from people.
How do these artificial teeth work?
These artificial teeth consist of a biodegradable outer layer that contains stem cells and a specific protein that activates cells so that they ripen in nervous tissue. Thus, it was achieved as, as Stem cells They turn into a new tooth, it connects the nerves of chewing gum. At the same time, this biodegradable tissue shell is also lost, which allows the tooth to appear completely. In addition, the tooth has a layer Rubber nanofibers That they expand and help to be built -in in its place, when there is nothing left of this roof.
This is very positive, because it does not require as much operation as with ordinary implants. In this case, artificial teeth grow in chewing tires, as if they were natural.
How was it tested by mice?
The first step in the research of mice was to check whether artificial teeth really grew in the gums of mice. The results were expected in this sense. Now, however, there is the most important step, since the researchers will analyze The activity of the brain of rodents When they take food. The goal is to check whether they can really feel Through the teeth.
If it is confirmed that this is possible, these artificial teeth will definitely be on the right track. Logically, our dentist still has much, but this is the most interesting beginning.
