ABSTRACT:
This invention relates to an orthodontic appliance comprising of a plurality of brackets and molar tubes for the correction of malocclusion of teeth. The bracket features a horizontal rectangular slot in the gingival surface for securing round arch wires and rectangular arch wires in ribbon-arch mode. The bracket allows free tipping, controlled tipping or bodily movement of the tooth depending on the mode of securing the arch wire to the slot. The molar tube features at least one rectangular tube which is vertical in cross-section, corresponding to the arch wire slot of the bracket. The tube provides better control over the molar tooth leading to stronger anchorage. The appliance allows different tooth movements with total control for precise positioning of all the teeth.
