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.
VIP participants will have the exclusive opportunity to attend the practical portion of the course as observers.
You will witness the instructor perform each step while receiving detailed, step-by-step explanations of all clinical decisions. This unique format lets you experience real techniques in action and fully grasp the clinician’s decision-making process.
VIP participants will have the unique opportunity to participate in the practical part of the course in a «free audience» format.
You attend the practical part of the training. See how the lecturer performs each action and get detailed step-by-step reviews of all clinical solutions. This is an opportunity to see real techniques live and to better understand the doctor's logic, but without the opportunity to work with your hands. |

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.
Demonstration Masterclass: VIP Participants Only (24.01.2027)
Format: Observer
– 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.
