What is the result of a clockwise rotation of the mandible?
What is the result of a clockwise rotation of the mandible?
- Less anterior facial height and more horizontal change of the chin
- No significant changes in facial height or chin position
- More anterior facial height and less horizontal change of the chin (correct)
- Equal anterior and vertical facial changes
In Schudy's concept, what causes the mandible to rotate counterclockwise?
In Schudy's concept, what causes the mandible to rotate counterclockwise?
- Significantly less growth at the condyles compared to the molar region
- Equal growth between condylar and vertical growth in the molar area
- Upside-down positioning of the condyles
- Greater condylar growth than vertical growth in the molar area (correct)
