Edgewise appliance were non-programmed appliance. There were two basic short comings. First was bracket design problem and the second was heavy force requirement for the bodily tooth movement of the teeth. To overcome bracket design shortcomings one has to doextensive wire bending. For that an orthodontist should be skilled enough to do required wire bending for getting good results. The second problem of heavy forces for moving the tooth bodily, require greater anchorage preparation. Heavy force also compromises the health of the surrounding tissues. In 1970 Dr. Lawerence F. Andrews introduced straight wire appliance also known as preadjusted appliance, in which he tried to overcome the short comings of edgewise appliance.
