Teaser DGAO - 7th Scientific Congress for Aligner Orthodontics 2022

The DGAO Congress for Aligner Orthodontics

The accompanying industrial exhibition offers a comprehensive overview of the current products for all aspects of aligner therapy.

Congress 2022

Dear Sir or Madam,

what is certain is that nothing is certain. Not even that[1]. If you had been asked in 2019: Can our lives be changed forever if a person in Wuhan coughs, you would have put this question in the same category as: Can a butterfly flapping its wings in Brazil trigger a tornado in Texas?[2]. Her first "no" would have been refuted by reality, however. Perhaps the only positive thing about this whole C mayhem is that our complacent safety has been somewhat challenged.

But despite all the confusion, our everyday life went on - somehow. We have protected our fellow human beings and ourselves, treated our patients and educated ourselves through reading (Journal of Aligner Orthodontics) and digital lectures (1st Virtual DGAO Science Congress). Certainly nothing was the same as before, and we certainly missed the direct human contacts (private and professional). Now, however, there are good signs that we can return to a new but different normal.

Certainly part of this normality is the 7th Scientific Congress for Aligner Orthodontics, which will take place on November 18th and 19th in Gürzenich in Cologne, as in the past, as a face-to-face event and taking into account all conceivable hygiene measures. But if that's not safe enough, or if you prefer the digital version for other reasons, you can (again) participate remotely. In any case, you are all cordially invited by the entire board of the DGAO. As always, we have made the greatest effort with the program design in order to present to you the knowledge, insight and experience that has been accumulated in spite of all the adversities.

So even if almost nothing is certain, the DGAO is absolutely certain that this congress is worth attending!

With 28 speakers, 250 participants and 18 exhibitors, the 1st Scientific Congress for Aligner Orthodontics of the DGAO eV started in November 2010 in Cologne's InterContinental, today the Dorint Hotel am Heumarkt. A success across the board.

Since then, four more face-to-face events have followed with steadily increasing numbers of participants and exhibitors, which resulted in a move to Cologne's Gürzenich. Most recently, due to the pandemic, the 1st Virtual Congress was held, at which the DGAO welcomed 700 international participants. A unique, interactive 3D exhibition platform crowned this first digital event.

This year, the DGAO eV is organizing a hybrid congress in Cologne's Gürzenich, at which numerous renowned speakers will once again present their scientific contributions to the international audience. An extensive industrial exhibition and the gala evening at SkyKöln complete the program.

“Nothing stays the same” – 3rd Scientific DGAO Congress

With an impressive number of participants, the 21./22. The scientific congress for aligner orthodontics took place in November. Around 550 orthodontists interested in aligner therapy traveled to Cologne to find out about new developments in this treatment technique and to exchange experiences at the conference, which was being held for the third time after 2010 and 2012. The conference president was again this year Dr. Julia Haubrich, who, together with the DGAO board, had set up a scientific program that included many a lecture highlight. One of these highlights was B. the contribution of Prof. Dr. Erwin Keeve. In his lecture “Future of robot-assisted surgery”, he gave an interesting outlook into the future of robotics and navigation, looking beyond the aligners, which – if you observe the development of digital processes in dentistry alone in the last five years – sooner or later will also affect the orthodontics department.

A complete success with over 300 participants

With 320 participants, 32 internationally renowned speakers and 18 industry partners, the 1st Scientific Congress for Aligner Orthodontics in Cologne at the end of November 2010 was a complete success. The organiser, the German Society for Aligner Orthodontics (DGAO), drew a consistently positive conclusion.

For two days, specialist lectures on a wide variety of aspects of all existing aligner systems were held in the conference rooms of the renowned InterContinental Hotel in Cologne. The interested specialist audience was able to exchange ideas with internationally renowned experts in a pleasant atmosphere. The 1st Scientific Congress for Aligner Orthodontics was the largest manufacturer-independent event to date, which offered a forum specifically for aligner therapy.
