A material difference: Clinical excellence with the Invisalign System

What to expect

This webinar, delivered by Beena Harkison, will provide an evidence-based understanding of the Invisalign System. It will outline how force-based aligner therapy works, focusing on Invisalign’s Smart technologies and their role in delivering predictable tooth movement.

Beena will also explore key biomechanical principles, before critically reviewing the clinical evidence supporting clear aligner treatment, with specific reference to Invisalign.

A CPD certificate (in the name of the purchaser) will be available to download once viewing of this online lecture has been completed. It is a recording of a webinar delivered in July 2026.

Learning objectives

• Understand why a force-based clear aligner is an effective orthodontic appliance and how the three Smart technologies unique to the Invisalign System create a force-based system
• Understand the biomechanics of the Invisalign System using low continuous force with optimised attachments and aligner activations
• Critically appraise the evidence for clear aligner orthodontics and highlight research specific to the Invisalign System.

Meet the speaker

Dr Beena Harkison graduated in Dentistry from the University of Witwatersrand in 2001 and obtained her Master’s degree in Implantology (MSc Implantology) in 2004. She was a Research Fellowship Student at the South African Medical Research Council and worked as a dentist for both the Department of Health providing community care as well as working in a private practice that predominantly provided paediatric dental care. In 2011, Beena achieved an MBA from Imperial College, London and graduated with Merit.​

On moving to the UK in 2004, Beena worked for Image Diagnostic Technology where she was responsible for sales, training and education related to cone-beam CT scanners and implant planning software products, ultimately winning the “Best Distributor Worldwide Award”.​

Beena joined Align Technology in 2007 and was the recipient of performance-based European Awards in 2008, 2009, and 2012.  Beena progressed to the clinical team in 2013 as a clinical specialist before she was promoted to the Clinical Support Manager role in 2014.  In 2016, she moved to Amsterdam to take on the role of Clinical Operations Manager for EMEA, joining the European Leadership Team.  2017 saw her further promoted to Director of Clinical Operations EMEA and then to Director of Clinical and Professional Education in 2018.​

In 2020, Beena moved back to the UK from The Netherlands to practice clinical dentistry and facial aesthetics.  Her particular interests are in minimally invasive dentistry harnessing digital technologies such as the Invisalign system and intraoral and facial scanners. With these technologies, aesthetically and functionally orientated treatments are provided in a comfortable, predictable, convenient and safe manner.
