AO Technical Commission Experts Symposia
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 convened in Copenhagen, Denmark in 2023 and was led by Daniel Buchbinder and Michael Grant. This one-and-a-half-day event 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. Session topics included:
- 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 AO's key industry partner. The AO TC CMF community has pledged to collaborate in order to effectively address these clinical needs.
1st CMF AOTK Experts Symposium, Florida, US
The first AOTK CMF Experts Symposium was held on November 13–14, 2019, in Tampa, Florida, US. Daniel Buchbinder chaired the symposium which was attended by 14 surgeons and 9 representatives from the industry.
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 AO ITC, like no other association, enables international dialogue amongst key opinion leaders in their field. It has been an exceptional experience being part of this community.”
Sebastian Baumbach, participant of the 15th AO TC Trauma Experts Symposium (Europe)
Challenging cases - clinical need - robust examination
Since the first AO Technical Commission Experts Symposium was held in 2006, these events have come to be recognized as a critical component of the innovation development process.
