Bracket is an important part of fixed orthodontic technology. It is directly bonded to the surface of the crown with an adhesive, and the arch wire passes through the bracket to apply various types of orthodontic force to the tooth.
The brackets are made of stainless steel, bioceramics or composite resin, and their main function is to fix the arch wire, so that the arch wire can better play its role and transmit the corrective force, so as to control the three-dimensional movement of the teeth to achieve the purpose of orthodontic treatment.
