Orthodontic treatment is focused on teeth movement. By moving the teeth in the right direction, the clinician secures the optimal position, which ensures the correct bite and aesthetic results. Orthodontics has a myriad of possible movements, the major ones are reviewed below:
1. Root tipping. Tilting the root of the tooth without adjusting the apex of the crown.
2. Crown tipping. Tilting of the crown of a tooth without adjusting the root apex.
3. Translation. Shifting the tooth along the occlusal plane without altering the long axis’ orientation.
4. Rotation. Turning a tooth about its long axis.
5. Extrusion. Pulling a tooth out of the gingival tissue.
6. Torquing. Adjusting the inclination of a crown.
7. Intrusion. Moving a tooth inside the gingival tissue.
8. Distalization. Pushing a tooth along the occlusal plane away from the midline.
9. Mesialization. Pushing a tooth along the occlusal plane towards the midline.
10. Expansion. Moving posterior teeth outwards away from the midline.
11. Proclination. Tipping the crown of anterior teeth labially.
Attachments are needed In order to facilitate movements that otherwise would not have been aligner treatment. Placed on the teeth behind the aligner, they serve as an anchorage point for the aligners, allowing to do such movements as rotation or extrusion. Below you will find the detailed description of the attachments used by eXceed.
