Active Wing Lingual Orthodontic System & Clinical Application -- Direct Bonding, Easy Torque, Invariable Force, One Main ArchWire

Introducing a new lingual orthodontic appliance: The anterior teeth bracket is composed of a base and a detachable wing. The .012" or .014" NiTi auxiliary arch wire that goes through a 0.5mm diameter transverse tube on the base is for aligning the anterior teeth. The wing with a invariable force spring connects the .025"x.019" NiTi main arch wire to the bracket base, closing the extraction gap or retracting the protruding teeth while exerting light force to control the torque, angulation and alignment of the anterior teeth. All devices including molar lingual tube and premolar bracket with variable sizes slot can be directly or indirectly bonded. The target position of the teeth are based on the main arch wire with established arch form and occlusion plane. The first bonding and regular adjustment occupy the dental chair for a short time and the total treatment is done mostly within 12 months. The unique biomechanics has many advantages in non-surgical correction of adult skeletal deformities. The application of thousands of patients in multiple countries has shown definite results.
