A 3D print

J5 MediJet™ gives University Hospitalof Southern Denmark, Esbjerg new
pathway to improve presurgicalplanning and research.

Surgeons are already saying
things like, ‘we don’t want to
do this surgery without a 3D
printed guide.’”Michael Boelstoft Holte

The head of the Department of Oral andMaxillofacial Surgery reached out to Prof. Holte,
who was working as an associate professor ata local university at the time, to think about asolution. Because they needed a 3D printing
system that they could use on a daily basis,
Prof. Holte suggested that the hospital establish
an in-house lab to manage model production
effectively.

Michael Holte, PhD, is the head of the 3D lab,which provides patient-specific 3D printed solutions
for several departments at the University Hospitalof Southern Denmark, Esbjerg. Before the 3D lab
was established the hospital’s Department of Oraland Maxillofacial Surgery worked with a third-party
service bureau to prepare 3D models to assist inplanning for corrective jaw surgeries at the hospital.
As the surgeon’s requests for 3D printed medicalmodels grew over time, the department found it
difficult to sustain the business model both froma budget standpoint and managing the iterative
process of revising 3D models in a timely manner.

The new in-house lab, which is now 3D Lab
Denmark, began to produce single-material models
with an SLA printer in the beginning of 2018. Themodels were sufficiently detailed and surgeons inother departments around the hospital began toask the lab to print models for them, too. Today,3D Lab Denmark has produced more than athousand 3D printed parts.
“It became an innovation hub,” Prof. Holte said.
“Surgeons had ideas that fostered dialogue andcreated new areas for 3D printing.”
Over time, Prof. Holte and his team realized that asingle-material printer couldn’t meet the demand
to print more advanced models such as hollow
models, multi-colored models, multi-material ormore realistic prints for better research and surgicalplanning.

StudyTitle HereIn their search for a more advanced 3D printer, thelab found the Stratasys J5 MediJet PolyJet printer.
The J5 MediJet has allowed the lab to produce
surgical guides with biocompatible and sterilizable
materials, it prints models with highly detailed
surfaces or with varying elasticity and softness.
In the short time the hospital has had theMediJet, clinical staff have used the 3D models
for presurgical planning, surgical guides,patient education, and research. It’s not just thedepartment of Oral and Maxillofacial Surgery that’s
asking for prints, either—the orthopedics and ENT
departments are asking for models frequently, too.

People say a picture isworth a thousand words,
but a 3D print is worth athousand pictures. The
possibilities are endless.”

Researchers at the hospital are currently studying
the best method for planning and printing positionalguides for total shoulder arthroplasty. Placementof the glenoid implant can deviate quite a bit fromthe anatomical orientation, and 3D printing theguide helps the surgeon place the prosthesis in theshoulder more precisely.
The study will help identify the most efficient
workflow for printing surgical guides. Researchers
are also evaluating whether 3D printing the surgical
guides makes a significant difference in improving
surgical outcomes for patients—and according toProf. Holte, surgeons at the Hospital are starting torely on the 3D-printed guides.

Looking into the future, Prof. Holte is exploring
additional areas of interest such as automation
and artificial intelligence, training and education,
incorporating 3D printing with additional
technological advancements. “There are many
possibilities. Our knowledge is developing throughinteraction with clinical staff and networking
through different professional forums. 3D labs allaround the world are looking into this development.
Even in Denmark we see additional 3D labs and3D printing centers popping up and it’s interesting
to see, it is becoming more prevalent.”4J5 MediJet:
