Kazumi Ikeda’s TMJ-First orthodontics — stabilise the mandible, then move the teeth
Orthodontist Kazumi Ikeda, who has headed the Roth Williams Center in Japan since 1990, condenses more than three decades of clinical work into TMJ First Orthodontics. Author’s course by Kazumi Ikeda. Six lessons totalling 8 h 35 min explain how to diagnose mandibular position, deal with disc displacement and 3D discrepancies before treatment, and use Roth mechanics to keep the mandible stable once braces come off.

What you’ll be able to do
- Tell a stable from an unstable mandibular position at the first consultation
- Use CBCT and MRI to read TMJ condition and recognise normal joint images
- Stage disc displacement in growing patients and time splint therapy against orthodontics
- Prioritise correction of vertical and lateral mandibular discrepancies in the plan
- Apply Roth straight-wire mechanics, torque and molar vertical control for lasting stability
Inside the course
Finding the true mandibular position
Ikeda starts with why the jaw position recorded at a first visit is often unreliable, how muscle relaxation reveals the real one, and how to analyse cases referred from other practitioners.
Disc displacement in young patients
A full lesson looks at how common disc displacement is among growing orthodontic patients, how it can progress, how to judge its stage and when a splint should come before brackets.
Discrepancies and mechanics
Three-dimensional mandibular discrepancies are built into planning with a worked case, followed by Roth’s modifications of the Andrews straight-wire approach, en-masse anterior retraction and vertical molar control.
Face, growth and function
The last lesson ties mandibular growth and joint health to facial aesthetics and closes with protocols for functional occlusion and analysis of joint movement.

Before you buy
Does the TMJ-First method require MRI for every patient?
The course presents CBCT and MRI as diagnostic tools and explains how they inform assessment; how routinely you image remains a clinical decision.
Has Ikeda written books on this approach?
Yes: TMJ 1st Orthodontics appeared in 2014, followed in 2021 by Face Design and Orthodontics.
Do I get CME credit or a certificate?
No. Clinicapedia provides the educational content only — no CME or CE credits, MOC points or certificates of completion are included with this product.
