CHAPTER 5 Treatment stages
Differential tooth movement, as previously defined, involves repositioning of the crowns of the teeth first, followed by root uprighting to the new crown positions. However, there is a prescribed overall sequence of tooth movements, in the correction of any malocclusion with Tip-Edge, that needs to be followed closely. It is basically very simple and goes as follows:
Normally .020 inch high tensile stainless archwires are preferred during this stage, since they offer easy free sliding through the molar tubes, yet have enough flexibility to correct molar rotation. However, the extra robustness of .022 inch wires may sometimes be indicated, such as when expanding maxillary crossbites, or when protracting second molars across first molar extraction spaces.
