How are braces?
The first is to say that the bracket system consists of several components - brackets, rings with locks, orthodontic arch, elastic traction and litagury. All of these components are installed at the beginning of the alignment of the dentition and removed at the end of the process.
Each tooth braces glued with a special adhesive. By orthodontic braces attached to the arc and tied litaguram. At the rear and side set teeth ring with locks.
All this construction is "working" on straightening teeth on the upper and lower jaw, dental braces are rarely installed on one of the jaws. The exception is when you want to combine different types of braces - on the top set the aesthetic system of translucent plastic, and the bottom usual.
Thus, the bracket system is the best way to create a smooth and beautiful smile for a lifetime.
