Invisalign Scientific Symposium’s inaugural digital edition attracts more than 1,400 delegates from 75 countries


The 2020 Invisalign Scientific Symposium, held on 15 and 16 May 2020, was conducted from a TV studio and featured a roster of global clinical and orthodontic speakers. The speakers shared scientific data and their best practices for treating Class II deep bite, and surgical cases in both adult and growing patient populations including Phase 1 treatments for younger patients. This is on top of the Invisalign System with mandibular advancement for teenagers.

The virtual format reflected Align Technology’s commitment in sharing forward-thinking knowledge and arming orthodontists and dental practitioners with clinical sessions  so as to learn from  peers, exchange best practices and move forward with their clinics.

The Scientific Symposium attracted 1,400 delegates, including over 1,000 orthodontists and 400 university students from 75 countries worldwide. Dr Beena Harkison, former clinical and professional education director of Align in EMEA region, moderated the event.She highlighted the clinical data on the use of the Invisalign system as compared with traditional treatments such as the use of a fixed appliance.

Dr Alessandro Greco who runs an exclusive Invisalign system practice in Rome, Italy, presented the first clinical case. In his lecture, he addressed the perception of aligners and their capacity to help patients with deep bites. He demonstrated a case using the G5 features of the Invisalign system, including bite ramps and pressure areas. Dr Greco concluded that the G5 protocol is effective and efficient in correcting severe deep bite.

Dr Dieter Brothag, a digital orthodontist from Germany, compared clinical outcomes of fixed appliance techniques with Invisalign. He concluded that the Invisalign System is a tremendous practice builder and the treatments are proven to be faster than fixed appliance techniques while offering more comfort and greater hygiene.

Dr Federico Migliori from Italy spoke about the predictability of distalising with aligners referencing to the systematic review done by Rossini in 2017 which states that 2.5mm is predictable. He concluded that using the Invisalign system with class II elastics and distalisation was predictable. It was more effective at controlling the vertical dimension and lower incisor proclination. Distalisation was achieved in an average of 15 months, which was shorter than treatments completed with fixed appliances.

Dr Simona Dianiskova from Slovakia discussed how they de-rotated upper first molars up to 2mm with expansion to correct a class II malocclusion. She explained that there was a significant statistical increase in condylar distance revealing a greater response of the mandible with expected growth using class II elastics and Invisalign system. Good vertical control was also noted. The duration of treatment was between 16 and 21 months.

Dr Sandra Tai’s study concluded that there was better skeletal change using mandibular advancement with the Invisalign System, as well as better control of lower incisor inclination. The study also revealed that mandibular growth was enhanced, and Invisalign aligners controlled the vertical dimension very well.

The study, along with Dr Dianiskova’s using class II elastics and Invisalign system for distalising or mandibular advancement, showed that there were no or only minimal changes to the incisor inclination.

Two more studies about expansion were also presented at the Symposium. Firstly, Dr Silvia Caruso from Italy assessed the amount of expansion which can be achieved using the Invisalign First System. The study concluded that using the Invisalign First system for expansion is predictable on the buccal cusps. Palatal expansion was predictable in canine to canine region and less predictable in the molar regions. 

The duo of Dr Tommaso Castroflorio and Dr Francesco Garino also presented a similar study relating to Invisalign First. The authors shared that expansion was the greatest between primary canine to primary canine region, achieving more than 3mm of expansion.

The two studies showed that expansion can be achieved using aligners. It also demonstrated that expansion is greater in the anterior region than in the posterior, and it is more predictable in the buccal plane than it is in the palatal plane. 

Dr David Couchat from France talked about dealing with impacted teeth, “The tracking of an impacted tooth is always a challenge but since I have been using the Invisalign System, it became finally easier and better. The situation is completely different if you consider tracking a tooth for an adult or a teen.”

Align Technology also previewed other campaigns that it plans to launch this year to further support digital orthodontics, includingan upcoming marketing campaign entitled “Invis Is Your Brilliance. Enhanced.”

Peer recognition

Attendees were also offered the opportunity to achieve recognition for their successful Invisalign treatment cases through votes.

Dr Mercedes Revenaz, a specialist orthodontist from Italy received the most votes. Dr Martin Pedernera from Spain, who won the 2018 Invisalign Peer Review Award, won the second place. Dr Cihan Capan, an orthodontist from Turkey, and founder and board member of DentGroup Clinics, won the third award.

Commenting on her win, Dr Mercedes Revenaz stated, “The digital edition of the Align Scientific Symposium, in my opinion, was a revelation in terms of the impact. The event was informative and was likely watched more carefully than any other live event. The doctors who use the Invisalign system are digital natives, and believe in the power of digital technology. It could only be a success! We all hope that in the near future, if the conditions are right, international events can be at least a hybrid, with the possibility of being followed live, but also via web.

I was so thrilled when Dr Mitra Derakhshan announced the award for my case. It made me believe that what I do for my patients every day is really important! I like to share my experience in Invisalign treatment to young patients because they really appreciate the digital workflow.”

The fight against COVID-19

Align Technology pledged to donate €50 to the World Health Organization in the fight against COVID-19 for each Symposium registered participant, with a total donation of €70,000.
