<p>The development of the pre-adjusted appliances, by<br /> Andrews, was a significant progress for the orthodontist,<br /> especially in the finishing of orthodontic treatments.<br /> A recent research shows that 71% of the orthodontists<br /> utilize one of the several types of pre-adjusted systems<br /> available. This type of appliance was developed to reduce<br /> the bends in the wires and, therefore, making the results<br /> more predictable. However, the slot designs of the<br /> pre-adjusted brackets can cause difficulties at<br /> the beginning of the treatment, especially the bracket slots<br /> of canine teeth.<br /> The replacement of the conventional pre-adjusted<br /> brackets on canine teeth for pre-adjusted Tip-Edge<br /> brackets conceived by the author, has solved problems in<br /> Straight-Wire conventional mechanics.<br /> From this new differentiated bracket indication on canine<br /> teeth, the author developed the Simplified Straight-Wire<br /> Technique. His 15 year-old experience developing this<br /> new proposal was reported in this work with more than<br /> 1000 pictures and 20 clinical cases described in detail and<br /> refinement in all the stages of the treatment, following a<br /> method proposed in the individual planning for each case.<br /> The described clinical procedures are an essential guide for<br /> the orthodontist for the understanding and utilization of<br /> this new proposed technique.</p>
