Dentist Andre J. Keet is the founder of IOS. The company structure was set up to be extensive and accessible. Many other courses that involve several blocks are literally viewed as real millstones. We decided  that the live seminars in orthodontics (Semios) should be offered as one-day courses on Fridays. They deal with a single concept. Although the topics do fit together as a series, it is possible to follow the seminars individually.
In addition, the Remote E-Learning in Orthodontics (Relio) was set up so it is possible to view the subject again or to study it only through the Internet.

As for case guidance, this will usually take place remotely: experience shows that during the course there is just too little time or the case can’t wait. What you can do is choose a product in Treatment Planning in orthodontics (Trepior) or send an e-mail with your request.
