Abstract
The pre-adjusted edgewise or StraightWire appliance was introduced by Andrews in the 1970s, largely based on occlusal cornerstones derived from analysis of untreated ideals (Andrews 1972). Specifically, Andrews isolated 6 keys to the ideal occlusion based on analysis of 120 non-orthodontic normal occlusions, namely:
