AO Technical Commission Experts Symposia

Where outstanding minds come together in a robust process to improve available treatments.

The Experts Symposia of the AO Technical Commission (AO TC) are well-established events to foster exchange among surgeons and representatives of our industrial partners with the overall goal to improve patient treatment. It is essential to review the clinical performance of implants, instruments, and the surgical techniques. Open and straightforward discussions are fundamental for identifying potential device improvements and refinements of surgical procedures. Consequently, the symposium format is fundamental in fulfilling the AO TC quality assurance mandate for newly developed devices when they become available for surgeons. The symposia have proven to be invaluable for defining the remaining unmet clinical need that is not yet addressed by existing solutions. This type of information is imperative to justify the initiation of new development projects, which makes the Experts Symposia highly appealing to our industrial partners. The information exchange at the symposia is strictly confidential.

The experiences over the past few years have reinforced the benefits of inviting experienced surgeons of all age groups to the symposia. While the more senior surgeons are familiar with the development history of implants and instruments as they became available, younger surgeons may be more apt to think out of the box. Since the initiation of the AO TC Experts Symposia in 2006 about 920 surgeons have participated and consequently, this AO TC network is rapidly expanding.

2nd AO TC CMF Experts Symposium, Denmark

The 2nd AO TC CMF Experts Symposium, a one-and-a-half-day event convened in Copenhagen, Denmark in 2023, was overseen by D Buchbinder and M Grant. It drew nine experts from five countries and attracted 23 participants from seven different countries. The symposium was structured into three distinct sessions, comprising a total of 18 case presentations, which were as follows:

  • Computer Assisted Planning and Patient Specific Solutions in Orthognathic Surgery
  • CAS and PSS in Orbital and Midface Trauma Surgery
  • CAS and PSS in Post Ablative Maxillofacial Reconstruction

Throughout the sessions, both the participants and faculty engaged in discussions that brought to light several challenges for the AO TC and the industry. The AO TC CMF community has pledged to collaborate in order to address these challenges effectively.

Plans are underway for the organization of the third AO TC CMF Symposium on September 6-7, 2024, with N-C Gellrich set to take the helm as the chairperson.

 

1st CMF AOTK Experts Symposium, USA

The first AOTK CMF Experts Symposium was held on November 13–14, 2019, in Tampa, Florida, US. D Buchbinder chaired the symposium which was attended by 14 surgeons and 9 representatives from the industry.

The three symposium sessions focused on:

  • Patient specific orthognathic solutions
  • Patient specific solutions for orbit and midface reconstruction
  • Patient specific solutions for CMF reconstruction following ablative surgery

The participants exchanged their case experiences to discuss and to identify opportunities for improvement. Recent advances in digital planning and innovative approaches to design and to manufacture patient-specific surgical guides and implants allow that complex surgical procedures can be performed in a highly reproducible manner independent of the surgical experience. Although the costs that are currently associated with the use of patient-specific implants and cutting guides are high, there is a clear trend toward their increased use because of the high predictability and accuracy that can be achieved and the potential to reduce operating room time.

The case winner was Ruediger Zimmerer, with his case about bilateral TJR with counter-clockwise rotation in mandibular hypoplasia.

The 2nd AO TC CMF Experts Symposium will take place on October 13-14 in Copenhagen, Denmark and will be chaired by D Buchbinder.


“The AO ITC, like no other association, enforces the international dialogue amongst key opinion leaders in their field. It has been an exceptional experience being part of this community.”
