Previous researches showed posterior teeth intrusion to treat openbite can improve chin morphology by counterclockwise mandibular rotation. In this lecture, I would like to show you the factors to be considered for obtaining profile improvement through intrusion treatment.
- Understanding the changes in facial skeleton and teeth that occur during intrusion treatment
- Understanding the related factors to consider during treatment planning for intrusion treatment
