Interventions

Molar distalization by aligners with attachmentDEVICE

1. Plaster dental models will be poured from the rubber base impression. 2. Digital dental models will be created through scanning of plaster dental models. 3. Planning of the aligners will be done on 3 shape clear aligner. 4. Aligners will be fabricated on 3d printed models. 5. Patient will receive the first aligner and will be instructed to wear it full time (except during eating and brushing) for 2 weeks. 6. Patient will receive the following aligner after 2 weeks. 7. Follow up visits every 4weeks until 6 months.
