He later obtained his PhD from the University of Groningen, Netherlands, in 2005.

Trained in Invisalign since 2001, Dr. Chan was appointed as a clinical consultant and has been lecturing for Invisalign since 2006.

He currently teaches orthodontics and supervises biomechanical engineering projects on a part-time basis at the University of Sydney. He has also contributed to orthodontic teaching programs at the University of Hong Kong and the National University of Singapore.

Dr. Chan has published extensively in leading international journals, including the European Journal of Oral Science, Annals of Biomedical Engineering,  Orthodontics and Craniofacial Research, American Journal of Orthodontics and Dentofacial Orthopedics, European Journal of Orthodontics, and the Australian Dental Journal.

An experienced international speaker, he has lectured at numerous conferences and received multiple awards for his research and presentations across Europe, Australia, and the Asia-Pacific region.

Dr. Chan is a Diamond Invisalign Provider and a former member of the Asia-Pacific Invisalign Clinical Advisory Board. He is widely recognized as a key opinion leader in the field of clear aligner systems and has provided Invisalign training to clinicians globally.

Abstract

Invisalign treatment has evolved from a modality once reserved for simple alignment into a sophisticated system capable of treating a broad range of malocclusions. With appropriate diagnosis, case selection, treatment planning and clinical execution, clear aligner therapy can deliver highly predictable and refined orthodontic outcomes.

This lecture will provide a practical overview of how clinicians can confidently incorporate Invisalign into daily orthodontic practice. It will explore why Invisalign may be chosen as a treatment option, including aesthetics, comfort, hygiene, digital planning capabilities and increasing patient demand. Key principles of case selection and treatment planning will be discussed, with emphasis on matching case complexity to clinician experience.

A variety of malocclusions will be presented, including crowding, spacing, deep bite, open bite, Class II and Class III correction, extraction and non-extraction treatment, and cases requiring detailed finishing. Clinical examples will demonstrate how attachments, staging, anchorage control, auxiliaries and refinements can be used to achieve excellent treatment outcomes.

Learning objectives

To help clinicians gain the confidence and knowledge needed to initiate and successfully treat a broad range of cases with Invisalign.

Abstract

Clear aligner therapy for growing patients has expanded significantly with the development of Invisalign First, Invisalign Teen, Invisalign Palatal Expander and Mandibular Advancement treatments. These innovations provide clinicians with new opportunities to manage children and adolescents using digital planning, staged treatment protocols and appliance systems designed specifically for growth and dental development.

This lecture will provide an overview of Invisalign solutions for younger patients, with emphasis on case selection, treatment objectives and clinical application. Key concepts in early intervention and growth modification will be discussed, including arch development, space management, transverse correction, sagittal correction and the timing of treatment in mixed and permanent dentitions.

Particular focus will be given to the clinical use of Invisalign Palatal Expander and Mandibular Advancement with Occlusal Blocks, including appropriate indications, treatment protocols, patient compliance considerations and expected clinical outcomes. Case examples will demonstrate how these systems may be integrated into modern interceptive orthodontic treatment for children and teenagers.

Learning objectives

To introduce clinicians to Invisalign solutions for children and adolescents, with a focus on new innovations such as Invisalign Palatal Expander and Mandibular Advancement with Occlusal Blocks, and their role in modern interceptive orthodontic treatment.
