Dear Colleagues,

Due to current situation under Covid-19 pandemic, recently we decided to hold the Turkish Orthodontic Society Congress, which has been organized every two years on October since the foundation of the society in 1985, as a virtual congress on March 12-14, 2021.

We all know from the excellent experiences that we have had for years; when congresses held physically, we fulfill our longings, we reinforce our friendships, and we exchange our knowledge and experiences. In short, these environments are remind us that we are a family. However, due to Covid-19, which affected the whole world and changed our lives, unfortunately we will only be able to see each other on screens this year. Nevertheless, we think that we can and we will fill this gap, with the nice and warm feelings of being a family, even in a virtual environment.

In each congress, the contributions of our guest speakers and the carefully selected and meticulously prepared abstracts from Turkey and all over the world, take our profession a step forward. We are waiting for your abstracts and studies. Let's experience our first virtual congress together.

It is my pleasure to invite you to our congress, with the hopes of  leaving the tension and sorrows of this very difficult year, and things will return to normal all over the world soon.

Yours sincerely,

Prof. Dr. Özlem SEÇKİN
Chairman of Congress

Dear Colleagues,

We are organizing the XVII. International Congress of Turkish Orthodontics Society virtually between 12-14 March, 2021. On behalf of the Executive Committee of the Turkish Orthodontics Society, it is my honor to invite you to this meeting, which excites us with its up-to-date topics and the fact that it will be held virtually for the first time in the 35-year history of the Turkish Orthodontic Society.

We determined the theme of this virtual congress as "Orthodontics in a Changing World". Due to the pandemic conditions, perhaps this is the most unique period all through our lives in which we are most open to "unforeseen changes and changing". As orthodontist and orthodontic students, we embraced technological developments and current orthodontic practices with curiosity and enthusiasm throughout our professional life. We believe that this virtual congress will provide an enjoyable and fruitful event for all participants and will expand our vision even more.

Under the title of "Orthodontics in a Changing World", we will examine the "adult orthodontics" topics for our adult patients, who have increased their awareness thanks to the irresistible rise of social media and "selfies". We will also include orthodontic treatments with "skeletal anchorage units" and "clear aligners" that have entered our professional life with the developing technology. Another interesting subject of our congress will be "artificial intelligence". We think that we will have the opportunity to refresh our knowledge and follow innovations with conferences, satellite symposiums, oral and poster presentations to be held on these topics. Another feature of our virtual congress is that all presentations will be translated from Turkish to English or from English to Turkish simultaneously during the congress.

We would sincerely like to thank the distinguished keynote speakers, oral and poster research presenters who will share their experiences and knowledge with us, the scientific and organization committees, sponsor companies and our congress organization company for their valuable contribution.

With my kindest regards,

Prof. Dr. Ayşe Tuba ALTUĞ
President of the Turkish Orthodontic Society
