Comments

1. This is a severe deep bite case.
2. Invisalign aligner is a great system to resolve deep bite problem without put on any bite turbos on anterior teeth, therefore patient still can eat easily.
3. Staged intrusion for lower anterior teeth was used to ensure intrusion performed perfectly.
