Abstract
Orthodontists have increasingly shown more interest in the problem of retracting permanent canines. This dental movement is necessary in space closure of the arch for resolving different orthodontic problems. Very often, the extraction of first bicuspids is necessary in cases where there is severe crowding due to a discrepancy in tooth size and jaw size. First bicuspid extraction followed by separate cuspid retraction may also be indicated in cases of dento-alveolar sagittal anomalies such as excessive dental protrusion of the upper and/or lower teeth. Separate canine retraction may be accomplished with elastic chains, NiTi compression springs, lacebacks, Poul Gjessing (PG) canine retraction spring, rare earth magnets or distraction osteogenesis. These tend to tax anchorage. Headgears or orthodontic implants may be used for anchorage enhancement. Turning the wheel back and improvising the age-old technique of moving teeth with open coil springs, the authors have devised this economical, intra-oral, biomechanically efficient anchorage conserving technique of canine Distalisation, with minimal increase in routine orthodontic armamentarium and patient co-operation, the reciprocal retraction of canines with the use of open coil springs. There is no published literature on reciprocal canine distalisation for an entire premolar width.
