Definitions

  • the present invention relates to devices used for straightening teeth & is concerned with an adjustable orthodontic bracket assembly with continuous adjustment in any 3 planes of motion X, Y, Z planes (tip, torque & rotational movements).
  • Orthodontic brackets are used to move crooked, malaligned or misaligned teeth and do so by controlling tooth movement in three dimensions namely vertical, horizontal and rotational.
  • a previously proposed orthodontic technique is the edgewise technique that uses so-called Edgewise brackets.
  • the Edgewise brackets have horizontal arch wire slots that allow good control of tooth movement in the horizontal and rotational directions.
  • Another previously proposed technique is the Begg technique that uses so-called Begg brackets.
  • the Begg brackets have a vertical extending arch wire slot that permits tipping in the mesio-distal direction.
  • Each tooth has a three dimensional position in the dental arch-i.e. in the x plane, y plane or z plane. It can also be called the tip, torque & rotation of the tooth.
  • the bucco-lingual positioning of the teeth (in set and off set) in occlusal view (1 st order) is, for instance, through different thickness of brackets' bases.
  • the 2 nd order bend (tipping movement) was achieved through slanting or angulating the slot.
  • the 3 rd order bend (torque) or the bucco-lingual inclination (crown-root) of the teeth is obtained due to the occlusal- gingival inclination of the slot, since a squared or rectangular wire is fit in the "slot".
  • the bracket pre-angulation in other words, an inclination of the "slot" in the mesial-distal direction, defines the tooth position in all the three planes.
  • the prescriptions of pre-adjustments are not efficient for 100% of the patients, because they are based on medium values and not on individualized ones. Because of that, the correct orthodontic treatment demands accomplishment of bends in the wires, rebonding and a lot of administration to reach an appropriate final result, in other words, the correct three-dimensional positioning of the teeth with periodontal health, stability and aesthetics.
  • the brackets and tubes possess a construction that doesn't allow any adjustment after bonding to the patient's tooth.
  • ADJUSTABLE ORTHODONTIC BRACKET WITH AN ANGLE MEASURING DEVICE solves and overcomes the difficulties and deficiencies of the existing technique.
  • the bracket can be re-adjusted to change the tip, torque, rotation without the need to de-bond it & extremely precise position of the tooth can be achieved with no wire bending. And the adjustment can be done by the operator himself & at the chair-side.
  • An adjustable or customizable bracket including a body member for fixing orthodontic arch wire in a position such that stress is generated & force can be applied to the tooth to be treated; a bonding base member for bonding the bracket to the buccal or lingual side of a tooth to be treated & a connecting member which is movable & connects the base to the face of the bracket
