The compensation of post-treatment incisor torque in sagittal jaw relationship / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the dental compensation in different sagittal jaw relationships.</p><p><b>METHODS</b>One hundred and fifty-seven post-treatment cases with satisfied outcome were chosen. Computerized cephalometric analysis was performed to evaluate the sagittal jaw relationship. Incisor torque were measured based on study models. Correlation analysis was performed.</p><p><b>RESULTS</b>Compared with skeletal class I cases, the upper incisors of skeletal class III cases were more proclined, and lower incisors were more retroclined; the opposite result was found in skeletal class II cases. Dental compensation in class I cases took place primarily at lower incisors.</p><p><b>CONCLUSIONS</b>Incisor torque control was important in patients with various sagittal jaw relationships.</p>
