ABSTRACT
<p><b>OBJECTIVE</b>To investigate the imtrusion of overerupted molars with microscrews as anchorage.</p><p><b>METHODS</b>Thirteen adult patients were treated with microscrew anchorage and fixed appliances. Twenty-three overerupted posterior maxillary teeth were intruded. The intrusive movement was investigated on cephalometric radiographs.</p><p><b>RESULTS</b>The molars were intruded and the occlusal plane was corrected successfully in all patients. The treatment period of intrusion was from 5 to 18 months (mean 10.4 months). Significant true intrusion of overerupted maxillary molars, ranged from 0.45 mm to 7.00 mm [mean (2.86 +/- 1.80) mm], was achieved (P < 0.001). The apical root resorption was not clinically significant and the bone level was unchanged.</p><p><b>CONCLUSIONS</b>The microscrew anchorage and fixed appliances were applicable and efficacious for intrusion of overerupted maxillary molars.</p>
