OVERVIEW

Chris Chang's Updated Protocols: Biomechanics, Impaction, Treatment with TADs and Aligners is organized by OHI-S and will be held from Oct 07 - 08, 2025 in Dubai, United Arab Emirates.

Total lecture time: 12 h

Description:
Chris Chang’s 2-day intensive seminar — the most anticipated event led by one of the most prominent and influential orthodontists in the world, renowned for his incredibly effective practical solutions.

This seminar is your opportunity to learn modern orthodontic protocols from one of its pioneers.

During this 2-day event, you will not only gain valuable orthodontic knowledge but also be inspired by Chris Chang’s exceptional energy and passion for advancing the field in the vibrant city of Dubai.

You will receive first-hand learning experience on highly demanded topics, including:
– Treatment of impacted incisors and canines in the upper and lower arches
– Advanced biomechanics for torque control
– Application of miniscrews and utilization of the infrazygomatic crest (IZC) and buccal shelf (BS) to treat extremely difficult cases
– Combining aligners with TADs for controlled, predictable treatment outcomes.

This event is a unique opportunity that will transform your orthodontic practice forever, equipping you with advanced skills and knowledge to deliver exceptional patient care.

PROGRAM
Day 1
Topic 1: Impaction Treatment, Part I — Maxillary Impactions
– The focus on management of impacted maxillary incisors and canines
– Minimally invasive techniques, including the VISTA approach
– Preservation of gingiva and reduction of overall treatment time
– Practical clinical strategies to improve treatment outcomes and patient comfort.

Topic 2: Impaction Treatment, Part II — Mandibular Impactions
– Challenges of treating mandibular impactions
– Safe and effective biomechanical approaches
– Use of buccal shelf screws and 3D lever arms
– Overcoming high bone resistance and anatomical limitations
– Practical methods to enhance precision, safety, and efficiency.

Topic 3: Advanced Biomechanics for Better Torque Control
– Innovations in self-ligating bracket systems
– Role of advanced slot and wire geometry (e.g., parallelogram slot with round-sided rectangular wires)
– Enhanced torque expression with improved wire-to-slot contact
– Importance of torque control in incisor positioning
– Integration of TADs in space closure mechanics
– Strategies for achieving precise and efficient outcomes in complex.

Day 2
Topic 1: Six Key Applications of Miniscrews, Part I
– Overview of over 23 years of clinical experience with miniscrews in orthodontics

– The focus on two key anatomical sites and advantages of these sites:
- Infrazygomatic crest (IZC)
- Buccal shelf.

– Clinical strategies to enhance:
- Anchorage control
- Treatment predictability in complex cases.

Topic 2: Six Key Applications of Miniscrews, Part II
– Exploration of two additional placement sites:
- Incisor region
- Ramus.

– Application in:
- Transverse discrepancy correction
- Management of complex impactions.

– Combining multiple miniscrew sites for:
- Greater biomechanical flexibility
- Efficient and stable treatment outcomes.

– Practical techniques for solving a wide range of orthodontic challenges with precision.

Topic 3: Aligners with TADs
– TADs as stable anchorage to support challenging tooth movements

– Facilitate difficult movements like:
- Forced eruption
- Mesialization
- Molar uprighting
- Management of impactions.

– Clinical cases demonstrating integration of TADs into various aligner treatment stages

– Synergistic use of aligners (pushing forces) and TADs (pulling forces)

– Learn how to combine aligners and TADs for optimal treatment outcomes.
