The year that takes a general dentist from referring aligner cases out, to running them with confidence. The 2026 cohort has just finished that year. The 2027 seats are open.
A year of real cases, hands-on sessions, and mentorship that closes the gap between the lecture hall and Monday morning. You leave able to plan, treat, and finish aligner cases in your own chair.
The year opens at The Hoxton in Brussels: a private offsite room, a small group, and the first case on the screen before the coffee is finished. From the first morning, this is not a conference. Everyone is here to work.
By March the theory has to survive contact with a typodont. Attachment placement, IPR, tracking checks, done and redone under the curing light until the movement you planned is the movement you get.
Screen by screen: planning software, tracking checks, finished smiles. Faculty and invited guest speakers take the room through real cases, one decision at a time. This is the part no textbook can do.
The cohort walks the floors of PEBS, Dr. Dumu's own practice, to see the whole machine at work: the workflow, the team, the patient experience. The year closed on October 18. The 2027 chairs are set again.
These are the weekend recaps exactly as they went out to the cohort's own following through the year: the modules, the guest speakers, the hands-on sessions, the next date. Unpolished on purpose.
Tap the phone to flip through. Weekend 2 closed with "the next training weekend will take place on June 19–21." It did.
Six two-day sessions, Thursday to Friday, from January to October. The program is the one the 2026 cohort followed.
Biomechanics, diagnosis and digital planning
Mechanics and the full cycle, with guest speakers and hands-on work
Attachments, auxiliaries and tracking, with guest speakers and hands-on work
Complex cases: spacing and crowding
Complex cases: Class II, Class III and open bite
Exam and awards, then a final day on patient communication, at a surprise venue
Master's in Dentistry and a four-year specialization in Orthodontics at Ghent, followed by five years of clinical supervision and organizing the COS conference. A member of the WFO, EOS, EAS and BBNO, treating Invisalign cases since 2014.
With fifteen years in dentofacial orthopedics, he runs two of Brussels' leading orthodontic practices and heads the orthodontics course at the Haute Ecole Libre de Bruxelles - Ilya Prigogine. Diamond Apex 2023-24 and 2025, he lectures across the world on both clinical technique and the art of patient communication.
Diagnose and plan cases with digital tools like ClinCheck.
Manage a full treatment cycle, from the first aligner to retention.
Treat spacing, crowding, Class II and III, and open bite.
Integrate a predictable aligner workflow into daily practice.
I learned tips and tricks with braces and aligners you don't hear in other courses. We covered more cases, more patients, how to work with Invisalign, working with insurances, practical tips, and troubleshooting.
It's nice that the group is quite small so we can all communicate, talk with each other, talk with the instructors. There's no shame. You can ask any question. By day two we were loosening up, and we dared to ask more.
A strong and informative start. Day two brought even more practical and theoretical knowledge. I'd love more workshops to practice clinical planning myself.
A starter kit (~€3,000) is available separately through our partner lab and is not included.
The cohort is small. Tell us about your practice and where you want to take it. We review every application personally.
