The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on mini/micro screw implantation for orthodontic anchorage.

  • Description

    This procedure is most commonly undertaken by orthodontists . Orthodontic mini- and microscrew systems have been developed from maxillofacial fixation techniques; they use mechanical retention for anchorage. They are small  self-tapping titanium screws.

     Under local anaesthesia a pilot hole is drilled into the maxilla or mandible and the screw is inserted through the bone cortex and into the alveolar bone using a screwdriver-like tool. More than one screw can be inserted if necessary.

    Orthodontic loading can be achieved immediately after insertion, although it is often undertaken at a second visit. Following completion of the orthodontic treatment the screw(s) can be extracted and the incision site can be expected to heal spontaneously.
