Biomechanics, Miniscrews, and MARPE. Hands-on Course by Kee-Joon Lee in Warsaw

Advanced techniques beyond textbooks: MARPE biomechanics and miniscrews in Kee-Joon Lee’s protocols!

We invite you to an exclusive hands-on course in Warsaw led by world-renowned expert Kee-Joon Lee, where you will explore the core principles of modern orthodontic biomechanics in both theory and practice.

This course integrates scientific principles with clinical application, enabling you to master advanced techniques in maxillary expansion and miniscrew biomechanics for precise, predictable outcomes.

Designed to help you confidently and safely apply MARPE and miniscrews in daily practice, the program emphasizes biomechanical control for achieving long-term stability—even in complex clinical situations. You will develop a clear understanding of how to plan tooth movement, manage anchorage, control reactive forces, and prevent complications, leading to more predictable results and greater clinical confidence.

Key topics of the seminar:

– Treatment planning and simplified biomechanics for incisor movement control
– Biomechanics for molar movement control
– Miniscrew placement and complication management
– Biomechanical rationale for MARPE protocols
– Clinical application of MARPE in the treatment of open bite, Class 3 malocclusion, and asymmetry.

The hands-on training includes:

– Selection of the optimal expansion protocol: “rapid for adults” vs “slow for children” (or vice versa)
– Expander activation: step-by-step protocol and force control
– Practical exercises on MARPE application in different clinical scenarios.

You will leave this course with an applicable biomechanical framework that directly enhances treatment predictability and improves clinical outcomes.

Program

Day 1

Theory

Goal-Oriented Treatment Planning and Basic Biomechanics for Incisor Control

– Concepts of force moment and center of resistance
– Force-driven approach
– Anchorage control in anterior tooth movement
– Protocols for preserving deeply impacted teeth
– What is the first step in managing tooth impaction?
– How to preserve a periodontally compromised tooth?

Basic Biomechanics and Molar Control

– Molar movement control using MAPS (molar axial positioning system) and MAUS (molar uprighting using spacers) protocols
– 3D and 4D control of impacted molar movement: when and how?
– Why is three-dimensional visualization necessary?

Miniscrews: Selection of Insertion Sites and Complication Management

– Anatomical considerations for optimal miniscrew insertion site selection
– Rationale for using interradicular miniscrews
– What to do in case of failure: miniscrew stability and complication management.

Strategies for Complicated Cases: Non-Prosthetic Treatment

– Translation and root movement of molars
– Is a lever arm sufficient for molar mesialization?
– Reconstruction of compromised cases for non-prosthetic treatment
– Managing ankylosis: treatment planning and force control for safe tooth movement without complications.

Day 2

Theory

Transverse Correction: Why Is It Needed?

– Diagnosis of transverse discrepancies
– Application of transverse correction in cases of severe crowding
– Biological rationale for managing transverse discrepancies.

Biomechanical Rationale for MARPE Protocols

– Comparison of MARPE and bone-borne rapid palatal expansion (RPE)
– Is MARPE mandatory for skeletal expansion in adults? Can conventional RPE achieve midpalatal suture separation?
– Stability of outcomes after MARPE
– Use of rapid palatal expansion and straight archwire systems for maxillary expansion.

Practical Guidelines for MARPE 

– Maxillary anatomy considerations for safe and effective MARPE placement
– Activation protocol: rapid vs semi-rapid expansion
– If no separation occurs, should expansion be accelerated or slowed?
– Does failure of separation necessarily indicate SARPE? If not, what are the intermediate options?

Clinical Application of MARPE in Open Bite, Class 3, and Asymmetry Cases

– Complications associated with failure of suture separation
– Considerations in treating asymmetries with MARPE
– Correction of open bite and Class III malocclusion: step-by-step protocol
– Monitoring and control of expansion forces to minimize complications
– Practical recommendations for treatment planning in complex clinical cases.

Hands-on

– Working protocols of the latest versions of bone-borne rapid palatal expanders (RPE) and MARPE systems
– Selection of the optimal expansion protocol: rapid expansion for adults vs. slow expansion for children (or vice versa)
– Expander activation: step-by-step protocol and force control
– Practical exercises on MARPE application in various clinical scenarios.
