3DHEALS 2020 Virtual Medical Summit: Comprehensive Look at Craniomaxillofacial 3D Printing

There were a multitude of sessions and sub-sessions to follow at 3DHEALS 2020 (running from June 5-6, 2020), with over 70 speakers and four workshops, covering many topics on complex design and patient-specific treatment. Here at 3DPrint.com, we have covered many stories on craniomaxillofacial surgeries, including exploring patient-specific applications , research into simulation , and the use of advanced 3D printed visualization and surgical planning guides .
In attending the virtual summit, however, we were able to hear from Dr. Devid Zille (Director of Applied Innovations at OsteoMed ), Dr. Rui Coelho (CEO at BoneEasy ), Zsolt Pasztor, PhD (Managing Director at PREMET ), and Dr. Albert Woo (Associate Professor of Surgery at Brown University )—professionals and innovators who put the wheels into motion for fabricating complex, 3D medical designs for intricate surgeries. As an interesting side note, Dr. Zille actually used to work in the automotive realm as a car designer and, yes, he actually designed wheels (see below).
Now, as an oral and maxillofacial surgeon, Zille states that he sees parallels between virtual surgical planning (VSP) and the spokes of the wheel that he designed below:

Zille also discusses the numerous evolutionary phases in 3D printing with training models, patient-specific models, cutting guides, and patient-specific implants.

Initially, the surgeon also stated that surgical planning with conventional methods can be extremely time-consuming and is not always predictable. Models allow for better diagnostics and treatment, and excellent training for everyone from medical students to surgeons.
Surgeries now can be simulated ahead of time, offering much better visual presentation and a foundation for nearly “anything to be developed over the mesh.” Zille points out that that includes cutting tools, but also patient-specific implants.
Dr. Rui Coelho went on to explain what is involved in biological design, as it requires engineering and architecture, as well as a surgeon.
“We should design a process where the experience of all of the designs could benefit new designs,” explains Coelho in his presentation. “Our design should answer to every anatomical detail. Not only to the bone but also the surrounding structures.”
Engineers must have time to examine the face of the patient, decide on materials for proper attachment (such as metal, PEEK, ceramics), create a prototype, and ultimately, improve the quality of life for the recipient.
