An opportunity to learn from one of the leading figures in modern orthodontics and the master behind refined and predictable biomechanics in orthodontics — Dr. Giorgio Fiorelli.

This 2-day advanced seminar is a must-attend event for all practitioners working with aligners, who really want to understand what aligners can truly achieve — and what they cannot.

Through a rigorous biomechanical approach and real clinical evidence, Dr. Giorgio Fiorelli will guide you through:

— The true force systems behind aligners
— The biological limits that influence predictability
— When and why aligners fail
— How to overcome these limitations using smart, low-visibility hybrid mechanics.

Key topics of the seminar include:

— The foundations of aligner biomechanics
— Limitations of tooth movements and anchorage issues with aligners
— Extraction and non-extraction cases
— Deep bite correction and expansion
— Anchorage with TADs
— Hybrid approaches for molar uprighting, deep bite correction, true intrusion, and space closure.

This seminar is your chance to learn first-hand and unlock the hidden potential of aligners by mastering the true, defined principles of advanced biomechanics.

Day 1

Morning Session

— Foundations of aligner biomechanics:

- Mechanical properties of aligner materials (PET-G, TPU, SmartTrack, TC-85)
- Stiffness, moment of inertia, span length and force delivery in thermoplastic appliances
- Stress–relaxation and clinical consequences
- Biological limits: capillary pressure thresholds and safe force levels.

Afternoon Session

— Limitations of tooth movements with aligners:

- Predictability of different movements
- Least predictable movements: rotations, extrusions, true intrusion
- Why aligners overload teeth: setup increments, material thickness, stress–distribution problems.

— Anchorage issues with aligners:

Threshold forces, resistance levels, equilibrium analysis
T1 and T2 phase of treatment.

— Clinical consequences: refinement cycles, uncontrolled tipping, anchorage loss:

- When aligners fail and why: evidence-based discussion.

Day 2

Morning Session

— Clinical case analysis and effective treatment planning:

- Extraction and non-extraction cases
- Deep bite correction: what is achievable vs not
- Expansion and asymmetrical corrections
- Anchorage with TADs: direct, indirect, and hybrid mechanics
- Sequencing movements to avoid loss of control
- How to assess predictability before approving the setup.

Afternoon Session

— Hybrid approach for molar uprighting:

- Why aligners struggle
- Simple aesthetic appliances for controlled uprighting: cantilevers and alpha-beta springs. With or without TADs.

— Hybrid approach for deep bite correction:

- Evidence-based approach. Real intrusion with aligners
- How minimal fixed appliances can produce true incisal intrusion.

— Intrusions and extrusions:

- Biological limits, span length problems, and force delivery issues
- Aesthetic auxiliaries for predictable vertical movements.

— Space Closure:

- Why aligners often fail to deliver the right M/F ratio
- Using aesthetic fixed mechanics to close spaces before switching to aligners
- Anchorage reinforcement strategies.
