Simultaneous incisor retraction and distal molar movement with microimplant anchorage.
OBJECTIVE
To show how microscrew implants provide orthodontic clinicians with several advantages, eg, the elimination of interarch mechanics for correcting sagittal discrepancies, the reduction of treatment time, the simplification of treatment mechanics, the correction of midline discrepancies without interarch mechanics, and the ability to move entire quadrants rather than individual teeth.


METHODS
A step-by- step procedure for inserting microscrews is shown, along with several treated patients, which together demonstrate the mentioned advantages of this technique.


RESULTS
The authors show how microscrews can rescue treatments that have achieved less than ideal occlusion during the course of therapy and offer readers explicit instructions for placing these microimplants.


CONCLUSIONS
Microscrews offer orthodontic clinicians a minimally intrusive method of intra-arch anchorage that can translate entire quadrants with no untoward reciprocal results that afflict interarch techniques. Clinicians can correct sagittal discrepancies and midline deviations, and gain space for arch-length discrepancies with judicious use of microscrew anchorage.
