Abstract: An interchangeable lock is applied to a bracket, consisting of a lock designed for use in orthodontic treatment which is used in conjunction with an orthodontic bracket having a base bonded to the tooth in which the interchangeable lock should be frontally inserted. This same lock permits additional adjustments of the arch wire in regards to inclination, angulation or torque as there always be three walls forming a U-shaped slot, allowing the position of the arch wire to be controlled in relation to its inclination and angulation while maintaining the position of the bracket in relation to the tooth. It is possible to identify, modify and control the position of the tooth by contact adjustment with the arch wire at any time during treatment without the need to remove the arch wire or change or adjust the bracket.

Abstract: Interchangeable lock applied to a bracket, consisting of a lock designed for use in orthodontic treatment which is used in conjunction with an orthodontic bracket having a base bonded to the tooth in which the interchangeable lock should be frontally inserted; on the outside of the orthodontic bracket that besides adding the functionality of connecting the bracket to the arch wire, this same lock adds the property of allowing additional adjustments of freedom between the arch wire in regards to inclination, angulation or torque as there will always be three walls forming the U-shaped slot, allowing the position of the arch wire to be controlled in relation to its inclination and angulation at the same time it keeps the position of the bracket in relation to the tooth; a feature allowed due its walls where the arch wire slide inwards suffering minimal friction, being possible to identify, modify and control the position of the tooth by contact adjustment with the arch wire at any time during treatment without
