Lecture Description

Lecture Description: Chin deficiency by Class II skeletal pattern is frequently accompanied by protrusive lip profile. Patients often complain lip protrusion rather than chin deficiency. 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.
