3DHEALS 2020 Virtual Medical Summit: Craniomaxillofacial 3D Printing Applications

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.

Clinical Applications and Case Studies

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.”

Regulatory Considerations and Safety

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.

Zsolt Pasztor, PhD, introduced himself from Hungary, explaining that Budapest is the capital of “dental tourism.” In using dental implants, placement is critical; however, 50 percent of patients do not have sufficient room for these medical devices, meaning that more ‘complex solutions’ like customized, patient-specific implants often offer success.

Research Breakthroughs and Innovations

Bone loss is a challenge for treatment

Development of implants includes:

  • Design
  • Measurements
  • Simulation
  • Consultation
  • Continuous improvement

Those are the cases that concern him the most, due to the extreme precision required in measuring. Insertion of implants in such surgeries requires state-of-the-art materials and technique.

Woo has also inserted implants in other severe cases; for instance, one patient was missing half of his nose due to cancer. With digital imaging, Woo was able to use a scan from the other side of his face to create an appropriate prosthetic. His team has also used 3D printing to sidestep the need for making molds. With 3D imaging, they are able to create the orthotic and go from there.

Biocompatible Materials and Processes

Dr. Woo concluded his presentation by explaining that he and his team are also using 3D technology for computational flow dynamics, creating new designs for treating spinal tumors.

Although originally set for ‘the heart of San Francisco’ as a venue, this year’s 3DHEALS Global Healthcare 3D printing conference became a virtual—and inspiring—event. Focusing on the continued impacts to the field of medicine, rather than cancel the annual event due to the COVID-19 restrictions, founder and CEO, Dr. Jenny Chen, committed to an online format, and along with seeing every speaker conform to the changes, she was even able to add 25 percent more in programming.

Frequently Asked Questions

How is 3D printing used in medicine?

3D printing is used in medicine for surgical planning models, custom implants, bioprinting tissue scaffolds, drug delivery systems, dental aligners, and prosthetics. It enables patient-specific solutions that improve outcomes and reduce surgery time.

What materials are biocompatible for 3D printing?

Common biocompatible materials include PEEK, titanium alloys (Ti6Al4V), bio-ceramics (hydroxyapatite), medical-grade resins, PLA for temporary implants, and hydrogels for bioprinting. Material choice depends on the application and required mechanical properties.

Is 3D printed medical equipment FDA approved?

Yes, several 3D printed medical devices have FDA clearance, including orthopedic implants, dental restorations, and surgical guides. Each device must go through the appropriate regulatory pathway based on its risk classification.
