OHI-S Force-Driven Orthodontic Mechanics Maxillary Expansion and Auxiliary Appliance Systems 6 lessons 3h 24min

Explore force-driven orthodontic mechanics with a focus on maxillary expansion, transverse correction, and auxiliary appliance systems, bridging classical orthodontic principles with modern evidence-based protocols. This course provides a deep understanding of the biomechanics behind RME appliances, transpalatal arches, quad helices, Nance appliances, and the Ricketts utility arch, empowering clinicians to design and execute predictable, efficient treatment plans.
Learning Objectives

Apply design, bonding, and activation protocols for rapid maxillary expansion (RME).

Navigate clinical decision-making for expansion timing in growing and adult patients.

Master the biomechanics and application of transpalatal arches, quad helices, and Nance appliances.

Execute segmental maxillary distalization using the Ricketts utility sectional arch.

Evaluate force systems, center of resistance, and control of unwanted side effects.

Implement activation protocols and compensatory mechanics in utility arch systems.

Target Audience
This program is designed for dental practitioners looking to master force-driven mechanics, refine their use of auxiliary appliances, and apply evidence-based protocols for transverse correction and maxillary expansion.
Best for Orthodontists, Pediatric Dentists, and Restorative Dentists.
