413 words, about 2 min02Craniofacial Growth and Development
The exam tests growth timing, pattern, and mechanism enough to decide when interception is possible and when it is not. Questions often use cephalometric superimposition, cervical vertebral maturation, and growth rotations.
386 words, about 2 min03Fixed Appliance Biomechanics and Treatment
The exam tests force systems, anchorage control, and mechanotherapy. You need to predict tooth movement from the moment-to-force ratio and to recognize when a planned movement is statically indeterminate.
