OHI-S Complex Orthodontic Cases. Braces, TADs, MARPE, Aligners 7 lessons 6h 13min

Overview Complex orthodontic cases demand more than alignment—they require control over space, skeletal relationships, and vertical balance. This course delivers a structured, biomechanically driven approach to managing challenging malocclusions using a combination of fixed appliances, aligners, skeletal anchorage, and digital planning. The program explores how treatment decisions change across different spatial dimensions, with a strong focus on extraction logic, vertical correction strategies, and anteroposterior control.
