Avoiding the mistakes in planning and management of aligner patients. What to do if everything goes wrong? Use of auxiliary techniques

The main mistakes in planning:

- Why don’t the aligners work in the patient’s mouth as on the virtual plan?
- How to avoid physically impossible movements for aligners

Auxiliaries:

- Complex rotation of incisors, canines and posteriors: how to avoid problems at the planning stage, how to rotate different teeth using chains.
- Extrusion. Attachments or buttons and elastics? How to easily extrude teeth for 1mm per week.
- The use of braces, miniscrews, elastics: possible side effects and how to overcome them.

Aligner pliers:

- Strengthening the retention
- Speeding up rotations
- Enhancing tipping and the other movements

Common mistakes when doing an IPR. What to do if you:

- Did not make an IPR on time
- Stripped excessively
- Damaged tooth anatomy

Aligner retention problems:

- Trays do not fit
- When should I do a refinement and can it be avoided?

Avoiding negative effects at the finish:

- Disocclusion in the posteriors
- Sagittal gap
- Incomplete movements
- Loss of angulation
- Loss of torque
- Unwanted intrusion (watermelon seed effect)
