With Dr. Chris Chang

Course information
Explore how Dr. Chris Chang approaches orthodontic treatment decisions across growing patients and challenging adult cases. Fourteen lectures connect early intervention, skeletal anchorage, digital planning and clear aligner therapy.
Follow the reasoning behind extraction and non-extraction plans, asymmetry treatment, open-bite correction and impacted-tooth management. The course also examines orthodontic preparation for implant treatment and minor surgical procedures used in orthodontic practice.
Who this course is for
Designed for orthodontists and dentists with an orthodontic foundation who want to examine the rationale behind more complex treatment plans.
Compare anchorage and appliance choices across different malocclusions and impaction cases.
Review digital planning, challenging movements and the role of adjunctive mechanics.
Explore the connections between orthodontics, implant-site preparation and minor surgery.
Diagnosis and mechanics
An appliance is part of the treatment plan—not the starting diagnosis.
Compare early treatment, Class II and Class III correction, and extraction decisions before reviewing the individual mechanics. Use the case discussions to examine why a particular combination was selected.
Connect the intended tooth movement with anchorage, timing and treatment limits.
What you’ll learn
Consider timing and diagnosis before selecting a treatment approach for growing patients.
Examine the role of TADs within fixed-appliance and aligner treatment.
Connect the proposed tooth movements with a workable biomechanical plan.
Review case-based approaches and the limits of non-surgical treatment.
Study maxillary and mandibular impactions as distinct planning challenges.
Relate orthodontic movement to implant preparation and adjunctive surgical procedures.
TADs and aligners
Dedicated lectures address challenging aligner cases, digital orthodontics and the combined use of TADs and aligners. Revisit these alongside the lessons on asymmetry, open bite and impaction.
