Les Essentiels by Global DComet Meetings Bourse, Paris

Our mindset

At MIOS, staying in our comfort zone was never an option.

Innovation is about evolution, not repetition. We keep asking how we can deliver more value to the surgeons who train with us, and that search for excellence led us to a brand-new concept.

The decision

We moved away from the traditional congress format to build something completely integrated.

The result

Four days, one integrated education experience.

MIOS Cadaver Lab

An intensive, hands-on day in the lab to master execution, step by step, with the whole MIOS faculty at the table.

20 January, Skylab, Nantes

MIOS Surgical Immersion

The symposium day with our entire faculty, from technique and planning to the lessons nobody teaches and how to manage the unexpected.

21 January, Comet Meetings Bourse, Paris

Les Essentiels by Global D

Two days to close the week with innovation from another level, bringing surgeons and orthodontists together.

22 and 23 January, Comet Meetings Bourse, Paris
