Comments
- The severe anterior open bite was closed with selective posterior intrusion.
- Maxillary crowding was resolved with the aid of expansion and IPR.
- Her convex profile was improved due to mandibular auto-rotation caused by posterior intrusion.
- The patient was very satisfied with final outcome which allowed her to smile with confidence and chew better.
- Invisalign is certainly a good option for patients with periodontal problems because it leads to fewer periodontal problems than fixed appliances during treatment.
