What should one know about bracket systems and removable platters?

There are 2 types of devices used to correct the position of teeth removable and nonremovable. During the process of milk teeth eruption it is possible to use a pre-orthodontic trainer. A firm silicone gum shielder will correct the position of teeth during the process of dentition. The child will wear the trainer for 1 hour during a day and while sleeping. This way one can minimize the possible consequences of the denture defects. The given method can be used only for children under 8 years. A trainer is a plastic platter used to correct the position of teeth of the maxilla or the mandible.

Removable platters

Removable platters are produced for every single patient individually and are properly fixed on the patients teeth. Such platter can be removed while eating or cleaning teeth. The device contains cutting loops, arches and springs used to straighten deformed teeth. If there is a necessity to broaden the jaw they place a screw between the platters to broaden the construction. Removable platters are frequently used to treat children of 7-12 years old.

Brackets are a nonremoveable construction. It is fixed on the patients teeth during the whole period of treatment.

System of brackets

Brackets are a nonremoveable construction used to correct the defects of denture. Using brackets is equally effective for adults and teenagers. The prototype of the system of brackets was invented by Edward Angle 100 years ago. A bracket is a very complicated construction and it demands particular accuracy and mastercraft to make it. In the middle of the last century a group of people with naturally perfect form of teeth was invited to develop the technology. The dentists measured the form, angle and direction of every tooth.

Later they created brackets that are now widely used by orthodontist all over the world. Brackets are fixed on the tooth with the help of special glue and lay the correction. To correct the position of teeth they use mechanic pressure on teeth passed from an arch and creating constant pressure on the irregularly placed tooth. Only nonremoveable constructions can change the direction of the tooth and turn it endwise. There is a question: why is this effective method of treatment so popular all over the world but not in Russia? The answer is simple: using brackets is not the cheapest way of correction.

Materials used for systems of brackets

High demands of the materials used for the systems of brackets and for their machine work make this method of treatment really expensive. The wire part of the system is made of alloys of nickel and titanium. The wire is very elastic and possesses a characteristic called the shape memory. Since the wire is elastic you can knot it, bend and twist but it will shape master mold as soon as the influence stops. The master mold is "remembered" by the wire. You can twist the wire in any construction but in certain condition (preset temperature of 36,6 degree centigrade) the wire will remember the old form and shape the preset outlines. The mold form is a perfect denture. Brackets are usually made of medical stainless steel.

Though the systems of brackets can be also made of gold, titanium, plastic, ceramics, unbroken sapphire, glass fiber, composite. People who suffer allergy can wear brackets of gold. The usage of special nonligature selfalloying foreign brackets produced by the GAC Company is especially effective as it is much easier to clean them and the treatment will take less time. Brackets made of unbroken sapphire are almost transparent and it is difficult to see them on teeth. These brackets are designed for people who want to be cured unnoticed. The whole stomatological sector is developing and orthodontology is not an exception. New methods of solving old problems appear and the approach is becoming more complex. Orthodontology includes many sciences physics, chemistry, theory of strength of materials, classical mechanics, mathematics, physical metallurgy. New bimetal alloys are being developed in the sphere of orthodontology. Those alloys are titanium and molybdenum, niobium and titanium, titanium and copper. Though there is no need to invent anything new as there is a reliable method. Problems with assembly, welding and soldering of the construction may appear. For example the alloy of titanium and molybdenum has the same characteristics as nickeline an alloy of titanium and steel.
