Orthodontic Treatment Mechanics and the Preadjusted Appliance

The introduction of the Straight Wire or Pre-adjusted Appliance, in the 1970s, was regarded as a significant advance in orthodontic practice. Its increasing use has led to a better understanding of treatment mechanics, yielding reliable and consistent results, to the satisfaction of both practitioner and patient. Today, the pre-adjusted appliance is widely accepted as the system of choice by orthodontic practitioners world-wide.
