Researchers at the University of Oslo, Norway, have found a new method of reconstructing the damaged jaw consisting of a kind of artificial mesh. Its role is to help the body generate new bone, as strong as the original.
In some cases, the jaw bone can suffer a lot of damage, largely due to an infection of the gums that causes the bones to break and the supporting teeth to come off. In some cases, the jawbone can be damaged due to a condition such as cancer or an accident or trauma, which sometimes causes disfigurement of the face. To repair the damage, dentists use the bone’s ability to repair itself. People need to understand that problems can arise during this fix.
Nowadays, bone can be regenerated with the help of healthy bone tissue as a basic material, which is prepared and implanted in the damaged place. In addition to this method, some doctors also use ground bones from other people and even animals. In any case, the substance obtained is neither strong nor porous to support the regenerated bone and can lead to the transmission of diseases. The operation itself is troublesome and there are possible complications.
To repair this bone, it will only be necessary for the edges and fragments to fit well, as it must be in close contact. If a bone breaks, a significant amount of blood accumulates there. The blood has in its composition organic molecules that are “welded” in long chains. This clot is filled with cells, which become a connective tissue and then calcify. The role of connective tissue is to form a porous platform for bone cells and capillaries. Bone cells reshape the calcified structure and form a functional bone, while the new capillaries help bring in nutrients and oxygen.
If there is a big difference between the two pieces of bone or if the edges have been damaged, the human body will not be able to repair the damage on its own, and because of this, the new technique has appeared. This allows a small piece of synthetic bone to be inserted into the real bone. The artificial mesh that is placed there will be as strong as real bone, and at the same time, porous enough for bone tissue and capillaries to grow inside and function as a reinforcement for new bone. This method allows the dentist to insert an artificial grid or net to determine where the new bone tissue will grow.
Such an intervention will require enough empty space, as they must be large enough to fit not only bone cells but also capillaries. The capillaries have the role of transporting nutrients and oxygen and eliminate disposable substances.
The artificial bone grid, on the other hand, is extremely porous, with a lot of empty space that can be filled with new bone. A very great advantage of this intervention is that the body assimilates the added bone. People should also know that the material used does not disappear from that place. It remains an integral part of the repaired bone and functions as a reinforcement.
The new method is not yet available to humans. This experiment was done on rabbits, pigs and dogs intends to conduct clinical trials in humans, especially patients who have had periodontitis and injuries to the jaw bone. If it works as expected, in a few years, the method may be available everywhere.
