Biomechanics, Miniscrews, and MARPE. Seminar by Kee-Joon Lee in Warsaw. "Standard" option

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

Join an exclusive seminar in Warsaw with world-leading expert Kee-Joon Lee, and explore how modern biomechanics truly works in clinical reality.

This seminar transforms how you approach complex orthodontic cases. You will learn to control force systems with precision, design predictable tooth movement strategies, and use MARPE and miniscrews as fully integrated biomechanical tools rather than isolated techniques. Emphasis is placed on stability, control, and complication prevention in demanding clinical situations.

You will leave with a practical biomechanical framework that directly improves treatment predictability and clinical outcomes.

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.

IMPORTANT: the "Seminar. Comfort", "Seminar. VIP" and "Practical Course" participation options are also available for purchase.

Advantages of the "Seminar. Standard" participation option:
– Participation in the scientific program
– Coffee break
– Notes and handouts
– Certificate of participation
– ADA credits available upon request.

Program

Day 1

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

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.
