MINI SCREW IMPLANT TAKING ORTHODONTICS TO NEW DIMENSIONS – A CASE REPORT.

Attainment and control of anchorage is fundamental and critical in orthodontics. Anchorage control throughout the orthodontic treatment is essential for uncompromised results. Conventional means of supporting anchorage have been using either tooth borne anchorage or extra oral anchorage. Tooth borne anchorage is one of the greatest limitations of modern orthodontic treatment because tooth moves in response to forces.  Extra oral anchorage can be used to supplement tooth borne anchorage, but requires excellent patient co-operation. Skeletal anchorage would offer tooth movement in any direction without detrimental reciprocal forces and simultaneously solving the problem of patient compliance. They expand the range of biochemical possibilities and orthodontic forces might be applied directly to the jaws through skeletal anchorage. In this case report, we are explaining an approach for skeletal Class I bialveolar protrusion, with microimplant anchorage used for retracting the maxillary anterior teeth.
