How do ODS Aligners move Teeth?
Clear aligners are but another Orthodontic technique to move and align the teeth. As they exert a very mild force on the teeth and as there are no attachments on the teeth,the oral hygiene maintenance is easier hence Teeth Friendly. How do ODS Aligners move Teeth?
The aligners while moving the teeth follow all the principles of Orthodontics. So when the tooth is being moved from A to B position there will be a stretch component on the A side and a crush component on the B side. The stretch and crush component works on the periodontal ligament thickness.
So to move the tooth from A to B position the pressure applied should be within the maximum movement in the periodontal ligament.
When a tooth is being moved from A to B position care has to be taken to check that the space to move the tooth should be available on the B side. Either, natural space or by interproximal reduction or by extraction.

For the tooth to move, the pressure has to be continuous so that means that the patient is supposed to wear the aligners maximum amount of time and should be removed only while eating and brushing.
In Aligner therapy, as there are no other orthodontic auxiliaries like wires and springs, the treatment happens by the fit of the aligner on the dental arch. When a tooth has to be moved from A to B, the fit on the A side will be absolutely snug or 100% and that on the B side it will have space for the tooth to move in the desired position. The movement is already calculated by the software.

To enhance the accurate movement the composite buttons or stops are made on the individual teeth or on the posterior teeth for anchorage. As the space for the movement of the tooth is limited the movement happens gradually, accurately and without much discomfort to the patient. The maximum movement happens on the first 48 hours after wear of the new aligner, so the patient should be advised to wear the aligners maximum during the first 48 hours.
