• Design and placement protocols for TADs in Class 3 correction
• Step-by-step protocols for non-surgical management of severe Class III cases
• Clinical case demonstrations and long-term stability outcomes.

Lesson 4: Overview of the New Damon Ultima System™

• Introduction to the Damon Ultima System: concept and evolution
• Key features and innovations compared to previous Damon systems
• Improved bracket design and torque control mechanics
• Integration with light-force archwires for efficient tooth movement
• Clinical advantages: precision, comfort, and reduced treatment time
• Case example illustrating system performance and outcomes.

Lesson 5: Popular Question to Chris Chang

• Treatment without MARPE
• Arch development with the Damon System
• Treatment of Class III asymmetry cases
• Why choose the Damon System?
• How to simplify treatment mechanics.

Lesson 6: Hot Tips for Impaction Treatment

• Challenges associated with maxillary and mandibular impactions in orthodontics
• Application of minimally invasive techniques, such as VISTA, for the treatment of impacted upper and lower incisors and canines
• Advantages of using VISTA in preserving gingival tissue and reducing treatment duration
• Strategies for achieving precise and efficient outcomes in complex.

Lesson 7: Advanced Mechanics with Aligners

• TADs for challenging tooth movements such as forced eruption, mesialization, and molar uprighting in aligner therapy
• Application of TADs at different stages of aligner treatment to manage impactions and other complex movements
• Protocols for designing treatment plans that leverage the complementary strengths of aligners (pushing) and TADs (pulling) to simplify complex orthodontic cases.

Lesson 8: Class 3 Treatment Mechanics with Aligners

• The role of temporary anchorage devices (TADs) in facilitating complex tooth movements during aligner treatment
• Application of TADs to perform bodily movements such as forced eruption and mesialization that are difficult to achieve with aligners alone
• Use of TADs in cases requiring molar uprighting and impaction management
• Combining aligners and TADs for optimal treatment outcomes.

Lesson 9: Case Report. Analysis of Discrepancy Index (DI) and Cast-Radiograph Evaluation (CRE)

• Introduction to Discrepancy Index (DI): definition and clinical relevance
• Components and scoring system of DI
• Overview of Cast-Radiograph Evaluation (CRE) and its diagnostic value
• Step-by-step protocol for calculating DI and CRE in clinical cases
• Case presentation: practical application and interpretation of DI and CRE results.

Lesson 10: Class 2 Treatment Mechanics with Aligners

• How to diagnose Class 2 malocclusion and evaluate mandibular growth potential to guide treatment planning
• Indications, biomechanics, and limitations of the FOUR Class 2 treatment designs:
• Class 2 elastics
• Infrazygomatic crest (IZC) screws
• Mandibular advancement (MA) devices
• MA combined with IZC screws.
• Selection and application of the most appropriate Class 2 mechanics in aligner therapy to achieve predictable treatment outcomes.

Lesson 11: Challenging Cases Made Easy with Screws: 6 Key Application Principles

• Identification of the FOUR key anatomical sites (IZC, buccal shelf, incisor region, and ramus) for miniscrew placement and their clinical indications
• Six innovative principles of miniscrew applications for managing sagittal, vertical, and transverse discrepancies, as well as complex impactions
• Protocols of miniscrew-based mechanics to improve treatment outcomes in complex orthodontic cases, including:
• Whole-arch distalization
• Posterior intrusion
• Crossbite correction
• Impacted tooth traction.
