Definitions

  • the present invention relates generally to an ancillary device for orthodontic applications and more particularly, but by no means exclusively, to ancillary devices for temporary anchorage devices, such as mini-screws, for correcting alignment of teeth.
  • Integrated anchorage implants are characterised by the implant fixture being in very close proximity to the enclosing bone, whereas non-integrated implants can be located in any bone adjacent to suitable mucosa, thereby increasing the range of possible locations for insertion. Further, non-integrated implants have a relatively less complex insertion procedure than integrated implants and allow for immediate loading.
  • Non-integrated implant is the temporary anchorage device.
  • Such devices include mini-screws, mini- pins, micro-screws and anchorage plates all of which can be fixed to suitable bone and comprise an end which extends out from the gum of a patient to be used for anchorage .
  • Mini-screws are miniature screws which can be temporarily fixed to the bone for the purpose of enhancing orthodontic anchorage.
  • Mini-screws can be placed in a variety of locations in a patient's jaw but are usually located between or near the roots of the patient's teeth or in the patient's palate.
  • mini-screws are particularly useful for closing gaps due to missing teeth, distalising or retracting teeth, intruding over-erupted teeth, reducing occlusal plane cants and the like.
  • Mini-screws can be used as either direct or indirect anchorage points .
  • Direct anchorage refers to applying an active force directly from the mini-screw to the "active unit" (i.e. tooth or teeth intended to be moved) .
  • Indirect anchorage on the other hand is used to describe situations where the mini-screw is used to stabilise a tooth or group of teeth to prevent side effects and allowing conventional mechanics to be used with no anchorage concern.
  • Ancillary mechanisms for applying the requisite force to the active unit include elastics and metal coils that take anchorage from the mini-screw.
  • mini-screws utilising such force delivery mechanisms suffer a number of deficiencies.
  • One such deficiency is that the level of force being applied by the delivery mechanism is not readily regulated or identified.
  • the force imparted by such delivery mechanisms is typically insufficient and the intensity decays quite rapidly requiring frequent reactivation.
  • attachment to the mini-screw can be quite complicated.
  • the ancillary will need to be wrapped tightly around the head of the mini-screw or specially bonded (e.g. using an acrylic) to ensure that it won't come off which can be time consuming and difficult to achieve depending on the location of the mini-screw.
  • the attachment can cause irritation to the patient.
  • an ancillary for an orthodontic anchorage device comprising: a coupling arrangement operable to be secured to the orthodontic anchorage device; and a substantially rigid arm extending from the coupling arrangement and operable to impart a force on an orthodontic arrangement by way of a magnetic system.
  • substantially rigid will be understood as being of sufficient rigidity to impart a suitable movement or anchorage force (i.e. for affecting tooth movement, providing anchorage for a tooth or group of teeth, etc.) but that may have some level of flexibility to accommodate forces produced by normal oro-facial function.
  • the magnetic system comprises a first magnetic attachment coupled to the rigid arm which is operable to either attract or repel at least one second magnetic attachment coupled to the orthodontic arrangement .
  • the orthodontic arrangement comprises a corrective device coupled to one or more teeth.
  • the corrective device comprises at least one of a plate, braces.
  • the second magnetic attachment is bonded directly to one or more teeth which comprise the orthodontic arrangement.
  • the ancillary further comprises a spacing means operable to adjust the spacing between the first and at least one second magnetic attachment.
  • the anchorage device is a temporary anchorage device (TAD) .
  • TAD temporary anchorage device
  • the TAD comprises a mini-screw.
  • the mini-screw comprises a non-circular head.
  • the coupling arrangement comprises a cap in accordance with the second aspect .
  • a cap for an orthodontic anchorage device comprising: a cover operable to be removably secured to a head of the anchorage device; and a receiving arrangement operable to receive an arm capable of imparting a force on an orthodontic arrangement .
  • the force is imparted by way of a magnetic system comprising a first magnetic attachment coupled to the arm which is operable to either attract or repel at least one second magnetic attachment coupled to the orthodontic arrangement.
  • the orthodontic anchorage device is a temporary anchorage device (TAD) .
  • TAD temporary anchorage device
  • cover is snap locked over the TAD. In an embodiment the cover is press fitted on to the TAD.
  • the cap further comprises a magnetic locking arrangement which is arranged to secure the cover to the TAD.
  • a void is defined in the cover, the void being operable to receive an outwardly extending flange provided on a head of the TAD.
  • the shape of the flange is non-circular.
  • the void may comprise a complimentary shape to the flange for closely receiving the flange .
  • the cover is secured to the TAD by use of at least one moveable magnet located within a second void adjacent the first void, the moveable magnet arranged to move towards a stem of the TAD when the head is seated within the first void.
  • At least one moveable magnet located within a second void adjacent the first void is attracted towards, and partially received by, a corresponding housing located within a stem of the TAD when the head is seated within the first void, to thereby secure the cap to the TAD.
  • the stem comprises at least one of a metal or magnetic material for attracting the moveable magnet (s) .
  • the cover is coloured to match the colour of the anchorage device insertion location.
  • a method of fitting the cap in accordance with the second aspect comprising positioning the cover over the anchorage device .
