So, their main development began after thermoactive nickel - a titanium alloy was invented. Began to do arches for briquettes of this unique alloy. Besides, nickel - a titanium alloy allowed to fix teeth much quicker.
How briquettes work?
In general briquettes represent the fixed orthodontic device. This device usually fastens to an external or internal surface of teeth. Each of briquettes has the individual program according to which the direction where tooth will be corrected is defined. Each briquette fastens to an orotodontichesky arch. It is an arch is the main source of force which allows to move necessary teeth by means of briquettes. Besides this arch, effort are created by special orthodontic rings, metal springs, shchechny locks, elastic chains.
Classical briquettes are arranged as follows: the orthopedic arch by means of metal or elastic ligatures is tied up to a briquette. Among orthodontists this process is called an alloying. Modern briquettes make a little in a different way. So, in particular are popular samoligiruyuyushchiyesya or bezligiaturny briquettes. In the last ligatures by means of which briquettes fastened to an arch, are replaced with the fixing element which is built already in a design of the lock. Nevertheless, efficiency of treatment by means of briquettes depends on professionalism of the orthodontist more. Efficiency of treatment depends on a type of briquettes less.
Many think that teeth are built in in a jaw tightly. Though if it was so, briquettes simply would not work. At orthodontic treatment teeth have ability to move. So, each tooth is in the hole and when small, but long pressure goes to a wall of a tooth hole, the hole starts resolving that allows to receive space for the movement of tooth. From other party where fibers of connecting fabric stretch, the bone which props up tooth is formed. For this reason tooth cannot return on a former place. Such property remains at the person during all life.
For each case the types of briquettes usually are selected. In order that it is correct to pick up briquettes, it is necessary to consider such factors as type of the wrong bite, need for surgical intervention, requirement of excess teeth at a distance, gravity of violation of a bite who will carry out treatment, what sum of people it is capable to lay out for brackets, for what term it is necessary to carry out treatment, and also the desire of the person is considered.
Today there are six types of briquettes are metal, ceramic, sapphire, lingvalny, titanic and Invisalign.
The most popular types of briquettes, perhaps, are metal briquettes. These briquettes are appreciated, first of all, by the reliability, availability and functionality. These types of briquettes are suitable both for children, and for adults and teenagers. Most of people thus usually prefer color options.
The main pluses of such briquettes is that they very strong, it is very difficult to break them. Thus they quite cheap. Besides, dark ligatures which are used together with metal brackets, do not paint and do not change color of teeth. When using such briquettes treatment duration usually is less. Thus they do not cause strong pain.
As for minuses, the first stage needs to be told that these briquettes look not esthetically and from the very beginning they quite inconvenient. Besides, such briquettes irritate a gum and can even cause emergence of ulcers.
Ceramic briquettes are produced from hi-tech glass and therefore the also rather strong. They are good that are almost not noticeable to people around. In general, as for pluses of this type of briquettes, first of all, it is necessary to tell that in comparison with metal briquettes, they have more esthetic appearance and are much less noticeable. Besides, ceramic briquettes are more convenient.
From minuses it is necessary to mark out that, ligatures are painted and look thus bad. Nevertheless, they change monthly. Besides, these briquettes are much more expensive, than metal briquettes. Thus at their use duration of treatment can be more long, than by means of metal briquettes. In addition, ceramic briquettes it is much more, than metal and at serious violation of a bite these briquettes cannot be used.
Sapphire briquettes are usually made of sapphires which were grown up in the artificial way. Such briquettes rather strong also possess high efficiency. Besides, sapphire designs are transparent and therefore them is practically not noticeable. Thus they usually are not painted from food. From minuses It should be noted that these briquettes rather expensive. In addition, sapphire briquettes demand that careful hygiene of an oral cavity was periodically carried out.
Sapphire briquettes are suitable for people who have no serious problems with a bite. Therefore they will not suit people who have a heavy form of violation of a bite. Such briquettes are made of strong plastic of a certain form which for each patient usually is selected individually. Sapphire briquettes do not cause irritation of gums and are not painted.
Lingvalny briquettes are good that are established on teeth from within. And therefore they in general are imperceptible, but it is obvious that it is much more difficult to establish such briquettes. Besides, such systems are quite difficult in leaving. Brackets for these briquettes are usually made of metal. To get used to them, usually it is required from three to seven days. It is also necessary to tell that from the very beginning they disturb the normal speech because of what language can hurt within two-three weeks. Thus the course of treatment usually is more, than with usual briquettes. If the patient has short forward lower teeth, they cannot be used. Besides, they are not used in the presence of serious problems with a bite. In addition, for treatment by the patient specially trained orthodontist has to be engaged in such briquettes.
Some people have an allergy to nickel therefore briquettes from traditional materials will not suit them and it is necessary to make briquettes of other materials, for example, from the titan. This material very strong and easy. Titanic briquettes are similar on metal, but thus is much more expensive. Mirsovetov notes what exactly from the titan many tooth implants are produced.
These briquettes look dolno esthetically. In comparison with usual brackets it is much simpler to look after them. They are removed usually before drink, meal, and also during toothbrushing. In comparison with the fixed catheters, they cause much less pain. Besides, on such briquettes never there are spots. When using this type of briquettes, the computerized planirovanny treatment is carried out. And the forecast of future result is formed even. Because these briquettes are removed, they already not constantly straighten teeth as other types. In general 20-22 hours a day are recommended to carry such briquettes, but in reality everything depends on the patient's habits.
