Orthodontics is a dentistry branch that deals with improper occlusion and crooked teeth correction. Modern technology offers a great opportunity for solving these problems with no age limit. Orthodontic constructions are made of modern, light, comfortable and safe materials. Currently the most popular and most effective way to correct the occlusion is using braces or brackets. This orthodontic system creates a dynamic and constant pressure on the improperly placed teeth, so that they can gradually move to their normal location. One of the most sophisticated developments in the field of orthodontics is the so-called lingual brackets. The construction is located on the inner surface of the teeth, creating a therapeutic effect and remaining invisible for the others.
