- Primary Outcome Measures
Name Time Method Amount of tooth movement<br>Parameter: The tooth position will be determined on each of the 3D models. The achieved 3D tooth position will be compared with the initially planned tooth position. <br>When: after completing the treatment<br>
- Secondary Outcome Measures
Name Time Method Amount of tooth resorption <br>Parameter: Panorama x-rays at the beginning and the end of the treatment<br>When: after completing the treatment <br><br>Uniformity of tooth movement<br>Parameter: The tooth position will be determined on each of the intermediate 3D models. In this manner the tooth position within each aligner change within the same setup step can be separately evaluated. <br>When: After each aligner change.<br><br>Wearing duration<br>Parameter: The wearing duration will be documented by the patient in a special wearing card. <br>When: during the wearing period of each aligner<br><br>Amount of the pressure on the teeth <br>Parameter: The amount of the pressure on each tooth will be documented by the patient on a visual ordinal scale. <br>When: during the wearing period of each aligner<br>
