Session I 3D PRINTING IN MEDICINE: HISTORY, APPLICATIONS AND ADT’S
Christensen, Andy *
Littleton, Colorado, United States
The advent of 3D Printing over thirty years ago spawned creative uses of 3D printed models in the medical space from almost day
one. This talk will focus on the major application areas for 3D printing in medicine as told through the history of their development.
Early applications for anatomical modeling are still relevant today but much of the excitement surrounding the use of 3D printing
for medical applications has come through surgical planning in conjunction with personalized templates, guides, prosthetics and
implants. The ADT has been a force for both developing and disseminating information for the use of this work in the head and
neck reconstruction space, which historically has been the clinical “driver” of this technology. Current and future trends for the
continued expansion of 3D printing within the head and neck reconstruction space will be addressed.
Biography: Andy Christensen has been active in the 3D printing (aka: additive manufacturing) industry since the mid
1990’s, the entire time with a focus on medical applications. He is a graduate of the University of Colorado at Denver,
with a BS in Business. From 2000 to 2014 he was the Founder and President of Medical Modeling Inc., a world-leading
medical device 3D Printing service bureau based in Golden, Colorado. Medical Modeling created entirely new toolsets
in the areas of patient-specific anatomical modeling, virtual surgical planning, personalized surgical guides/implants and
3D printed metallic implants. In 2014 Medical Modeling was acquired by 3D Systems and saw Andy lead the creation
of a new business vertical for 3D Systems in the Healthcare sector. Andy left 3D Systems in 2015 to pursue other
interests.

Objectives: Correct skill to handle the cutting device is indispensable to any surgeons. The lack of this may bring on overcuts
and damages to the surrounding tissue. This situation has risks of causing the subsequent complications or life-threatening
accidents by heavy bleeding and nerve damage. In order to solve these problems, we developed a remote controlled haptic robot
drilling system in oral and maxillofacial field.
Materials and Methods: The system consists of a master robot and a slave robot. The master robot is a robot that surgeons
operate, and the slave robot is a robot that interacts with the cutting target. The force and position of robots are transmitted in both
directions by bilateral control. White pine and balsa wood were used as phantoms. They have similar hardness of porous cortical
bone and dense trabecular bone as mentioned in Misch’s bone density classification. Both woods were bonded and drilled
continuously. The value of the force scaling function was calculated from the maximum motor torque and the cutting force by
using computer.
8
Results: As the force of master robot was increased, the force scaling function of slave robot decreased automatically in order to
avoid overcutting. It made slave robot stop at the position limitation and the error was in 60μm. It was only 2.5 % of 2 mm margin.
The situation of continuous drilling from starting point of pine surface, through pine and balsa, to stopping point after penetration
was displayed on a display screen.
Conclusion: The drill could successfully stopped within safe position at the position limitation. Higher accuracy was expected
by fine adjustment in force scaling.

AMANN GIRRBACH’S INTEGRATED CAD/CAM SOLUTION
Flores, Ramon *; Crispin, Chad
Amann Girrbach North America, LP
Charlotte, North Carolina, United States
With so many fragmented Cad Cam systems in the market, it is important to know what it is that one wants to accomplish by
finding the right system to use. Many labs/in-house labs will acquire a scanner from company X and a milling machine from
company Y. Amann Girrbach’s starting point is that we want to offer a user a complete in-house solution, where we own a
complete integrated solution from hardware to software, including an offering of a wide material indication beginning with
Zirconia to Soft millable CoCr, or a wide range of indications where a simple Zirconia crown can be milled, and after a quick
turnaround can be able to mill a denture shortly thereafter. Where system integration means that a user is able to have a peace of
mind because the R&D behind the company has taken care that the workflow is seamless and all the necessary digital integration
has been taken care of, this allows the user more productivity, less errors and down time through automation, but what is more
important, it brings more time to the user to maybe go home a little earlier in the day to enjoy time with his family.
Amann Girrbach is truly the most comprehensive in-house CAD/CAM solution on the market today. Amann Girrbach not only
manufactures all of the materials available, but manufactures all of the technology needed while providing support which is
unparalleled in today’s CAD/CAM arena. Amann Girrbach manufactures the materials which are proven to work every time
without fail. The materials range from millable wax, PMMA, zirconaiand block materials to a variety of millable metal materials.
They are used by Dentists and Laboratories all over the world daily. Amann Girrbach manufactures equipment for Model
Management, Scanning, Milling, and Finishing, to sintering for both zirconia and Cobolt Chrome. Amann Girrbach also develops
all of the software necessary to put it all together. The workflow is truly seamless because of the countless hours invested in R&D
to assure superior digital integration and increased productivity. Amann Girrbach has only chosen a few select partners in the

Keywords: Temporomandibular joint, Magnetic resonance imaging, Dynamic technique
Purpose/Aim: This study was aimed to determine and optimize the parameters for the MR fast imaging employing steady-state
acquisition (FIESTA) sequences, which was to obtain an acceptable image to evaluate the movement of the temporomandibular
joint using a 3.0-T imaging unit.
Materials and Methods: Ten volunteers were evaluated by static and dynamic imaging. The static images were obtained in
maximum open- and closed-mouthed positions in the oblique sagittal plane, with double echo proton density weighted/turbo spin
echo T2 weighted sequences. The dynamic images were obtained from a slow, consecutive open-closed movement. The cycle of
the open-close movement was unlimited. To obtain transverse images, dynamic imaging was performed along three axes of
mandibular rotation, in the planes perpendicular to the longitudinal axis of the condyle, the mandibular ramus, and the condylar
path.
Results: All of the images were successfully obtained from all volunteers, and the rapidity of dynamic FIESTA means this is a
feasible technique. The disc and condyle were well depicted where open-close movement was slow. In dynamic FIESTA MRI,
the direction of the mandibular movement and the perpendicular plane to the longitudinal axis of the condyle does not always
coincide. The plane in the direction of the condylar path had a slight predominance over the other two slices with respect to the
dynamic grasp of positional relationships in the articular frames.
Conclusions: Static imaging is the gold standard in the evaluation of the temporomandibular joint. Dynamic imaging is a valuable
tool that can provide additional information about the movement of the articular disc and the mandibular condyle.
Biography: Dr. Namiaki Takahara is Clinical fellow of Oral and Maxillofacial surgery, Tokyo Medical and Dental
University. He received a D.D.S. degree from Niigata University and Ph.D. from the Tokyo Medical and Dental
University. He has board Certified specialists of Oral and Maxillofacial Surgery and Temporomandibular Joint.

Introduction: Mandibular discontinuity, caused by tumor ablation or trauma, has normally been reconstructed by using
vascularized or non-vascularized block bones. However, block bones cannot reproduce the natural curve and configuration of the
defected mandible. In the 1990’s, several oral and maxillofacial surgeons attempted to produce a more accurate mandibular
reconstruction with a custom-made Titanium (Ti-) mesh tray and particulate cancellous bone and marrow (PCBM). A
commercially available Ti-mesh tray, called the “Dumbach Titan Mesh-System (DTM) (Stryker-Leibinger, Freiburg, Germany),
was also introduced. [3] Since then, mandibular reconstruction, using DTMs and PCBM, have been applied to a wide range of
mandibular discontinuity, and with reports on their clinical advantages being reported. Nevertheless, DTMs had limitations in
reproducing the configurations of defective mandibles and fitting to the residual mandible, due to the three-dimensional (3-D)
prefabricated configuration of the DTMs by the manufacturer. [4] These limitations may disturb the top-down prosthodontic
treatments after mandibular reconstruction. Unfortunately, DTMs have disappeared from market.
On the other hand, the physical models fabricated by computer-assisted design (CAD), computer-assisted manufacturing (CAM),
and rapid prototyping (RP) technologies have contributed to more accurate mandibular reconstruction. In fact, they have been
used for surgical simulation of mandibular reconstruction, and pre-processing or pre-fabrication of reconstruction materials.
Purpose: The purpose of this report is to propose a computer assisted mandibular reconstruction procedure, utilizing a custom-
made Ti-mesh tray with particulate cancellous bone and marrow, and a removable denture. This procedure was based on the top-
down treatment technique, and reviews the case of a representative patient with mandibular continuity defect.
Methods: The patient was a 74-year old female with a chief complaint of facial asymmetry and masticatory dysfunction. Due to
gingival carcinoma, she underwent a segmental mandibulectomy on the left mandibule.
On the VR space, using 3-D reconstructed computer tomography data, the residual right-side mandibular fragment was
repositioned based on the condylar position and the occlusal relation. The mandibular fragment was then mirrored for a central
sagittal plane. The position of the mirrored object was slightly arranged with the occlusal relation. Through the above operations,
the landmark configuration, for the custom-made Ti-mesh tray as a virtual simulation model, was fabricated. On the physical
model, we produced a custom-made Ti-mesh tray with a commercial Ti-mesh sheet. Surgical treatment was carried out using the
tray.
The denture pattern was designed by a dental technician on the VR space, fabricated using a 3D printer, and modified to create
an impression tray with resin. Using the impression, the temporary removable denture was fabricated.
Conclusions: We propose a computer assisted design for a custom-made Ti-mesh tray and a removable denture, based on the
Top-down treatment concept. We feel this technique is advantageous in reconstructing functional occlusion, and in accurately
regaining dental and facial aesthetics.

Keywords: 3-dimensional Model, Synthesis of Data, Dental Model Scan
Purpose/Aim: Recently, various three-dimensional (3D) data have been used in the dental and medical fields. In addition,
computed tomography (CT) images have been used to fabricate surgical support of 3D models in orthognathic surgery. However,
CT artifacts from metal prosthesis adversely affect the reproducibility of the 3D models. The purpose of this study was to evaluate
a new method for fabrication of 3D models of orthognathic surgical support using synthesized Maxillofacial CT data and dental
arch models scan data.
Materials and Methods: CT images were obtained with opened or closed mouth. The CT images were converted to
stereolithography data by image processing software (non-synthesized images). Dental arch plaster models were fabricated using
conventional dental impression technique. Dental model data was scanned by a 3D dental scanner. The CT data and the dental
model scan data were synthesized by CAD (synthesized images). The plaster models of these images were produced by a 3D
printer. The discrepancies between these models was evaluated using computer matching method software by root mean square
(RMS).
Results: The RMSs of the non-synthesized models become greater when the greater amount of artifact were observed, but those
of the synthesized model did not significantly changed regardless the amount of artifacts. In addition, the RMS of non-synthesized
models with open mouth showed significantly smaller comparing those with closed mouth. By contrast, the RMS of synthesized
models showed no significant difference between the images obtained with open mouth and closed mouth.
Conclusions: These results suggest the new method using synthesized CT and dental arch models is promising to fabricate
surgical support of 3D models.

3dMD- THE POTENTIAL FOR 3D TEMPORAL SURFACE IMAGING IN REGULAR
CLNICAL ENVIRONMENTS
Lane, Chris *
CEO 3dMD LLC
United Kingdom
The goal for any clinical imaging system is to present the anatomical truth of the subject being imaged. The move from traditional
photography to textured 3D surface imaging represented a massive improvement in terms of digitally recording and measuring a
patient’s surface information. Photographic analysis could be objective rather than subjective and errors caused by perspective
and the 2D plane of the camera eliminated. Temporal 3D imaging eliminates a further ambiguity by capturing sequences of images
over time, allowing a profile of movement and expression to be built. With modern interventional techniques the clinician has the
ability to engineer the dynamics of the body and face and it is becoming more important to record this an eliminates further
ambiguity in the anatomic model. This presentation highlights the road to developing useable temporal systems (5-60 3D frames
per second) for everyday use and highlights the fascinating parallels between clinical challenges and the emerging new worlds of
wearable technologies and intelligent fabrics.

primarily orthopedic myoelectric prostheses. We developed a noninvasive blinking periorbital prosthesis that can synchronize
with blinking of the intact eyelid by using surface electromyographic signals of the orbicularis oculi muscle.
Materials and Methods: Myoelectric potentials of the orbicularis oculi muscle while blinking were measured with surface
electrodes on the eyelid in four healthy adults. Possible crosstalk introduced via the electrodes was also measured and assessed to
determine whether crosstalk would affect surface electromyographic measurements while blinking.
Results: The amplitude of the surface myoelectric potential of the orbicularis oculi muscle was sufficiently high for the practical
use of blinking prostheses. Our blinking model was successfully synchronized with blinks of the subjects’ eyelids under
experimental conditions without crosstalk between the orbicularis oculi muscle and other muscles.
Conclusions: Although our study revealed several problems, the use of surface electromyographic signals could be a promising
and useful technique for synchronizing blinking of the prosthetic eyelid with blinking of the intact eyelid.

DIGITAL TECHNOLOGY IN ADVANCED JAW RECONSTRUCTION:
OUTCOMES OF IMMEDIATE INTEREST

Advanced Digital Technology has initiated profound change in approach to head and neck cancer resection, reconstruction and
rehabilitation. Cancer resection involving the jaws may present patients with considerable challenges in their survivorship. A
growing body of evidence supports that the primary needs of such patients in their survivorship is to have function: speech,
swallowing and mastication. The challenge has been how to achieve improved functional outcomes that are meaningful to the
patient. With the intuitive intraoperative surgery approaches used historically to reconstruct jaws with bone containing
microvascular free flaps, the spatial positioning of the bony reconstruction and hence the spatial positioning of osseointegrated
implants was not predictable. The use of digital technology with surgical design and simulation (SDS) as well as additive
manufacturing (AM) allows for improved and predictable spatial positioning of the osseous reconstruction and osseointegrated
implants. The outcomes of these innovative treatment approaches need to be measured to determine the precision of planned to
achieved anatomical result. Functional outcomes also need to be measured to determine that the primary need of patients is being
achieved. The presentation will discuss early results that are emerging with regard to spatial and functional outcomes in advanced
jaw reconstruction that makes use of SDS and AM.

Keywords: computer-guided implant therapy, immediate loading, cumulative survival rate
Purpose/Aim: Recently, the use of CT scans and surgical planning software to produce a CAD/CAM surgical template with a
prefabricated provisional restoration for immediate loading can make implant placement more predictable and effective for
patients is watched.
15
Materials and Methods: This report is that a computer-guided surgical technique for the partial and fully edentulous patient,
with a provisional restoration fabricated prior to implant placement, for immediate loading using advanced digital technology
(ADT) that is NobelGuide® (Nobel Biocare, Switzerland). We analyzed a cumulative survival rate of implants in edentulous
patients with this therapy for 8year 4months after loading. A structured study was used to find out the edentulousness based on
missing teeth classification.
Results: In this study, total of 129patients (469implants (Nobel Biocare, Switzerland)) were enrolled. 56cases 121 implants were
bounded edentulous group 29 cases 123 implants were cantilever edentulous group 44 cases 225 implants were full edentulous
group. Cumulative survival rate was 95.5% for 8year 4months after loading.
Conclusions: The computer guided surgical technique is minimally invasive surgery, which does not need to open major flap,
achieving immediate functional loading to the implants by using prosthesis. Moreover, this treatment has high survival rate of
implants. It indicates that this implant treatment is very reliable treatment for edentulous patients without having parafunctional
oral motor behavior.

Orthopaedics and Cranio-maxillofacial divisions our engineers are helping surgeons plan complex procedures. Our 3D printed
surgical guides include joint replacement guides for knee, shoulder and hip replacement surgeries, osteotomy guides and CMF
guides. Specifically in CMF, we are partnered with DePuySynthes CMF to provide customized surgical planning services
alongside their reconstruction hardware. The typical workflow for surgical planning begins with CT images that are segmented
to create a 3D representation of the patient’s anatomy. An interactive web session allows surgeons to plan osteotomies, reposition
anatomy and try various treatment plans virtually. Once a plan is finalized, custom guides and models are designed and shipped
prior to surgery to help transfer the planning in to the operating room.

AUGMENTED REALITY USING THE BINOCULAR TRANSPARENT SMART
CLASSES FOR SURGICAL NAVIGATION
Itamiya, Tomoki *
Aichi University of Technology
Department of Engineering
Gamagori, Aichi, Japan
Keywords: Augmented reality, Smart glasses, Surgical navigation
Purpose/Aim: Using a transparent smart glasses is very useful for surgical navigation because a surgeon does not need to move
his/her line of sight from the operative field.
Materials and Methods: We propose the application development method that is able to be a stereoscopic vision of 3D-CG
medical model using a transparent smart glasses. We did Augmented Reality (AR) by using a smart glasses. We use EPSON
Moverio BT-200 as smart glasses. Unlike competitive models, its each lens has its own display composed of micro projector and
half mirror. With a front-facing camera and motion tracker, BT-200 can recognize AR marker or 3D printed model. Therefore,
we can see a stereoscopic vision of 3D-CG medical model projected into our surrounding. BT-200 work out of the box with
Android apps. We developed Android application using Qualcomm Vuforia which is a software developing library. A stereoscopic
vision of 3D-CG medical models made from CT/MRI image data is possible by using the application.
Results: A user can make the application software within only five minutes by preparing 3D medical model file for instance STL.
Therefore, a surgeon and a dentist and a clinical staff can make the AR 3D-CG content easily by oneself. One plastic surgeon is
using our method for his daily operation for instance Zygomatic bone fracture.
18
Conclusions: This method is effective for informed consent and education. It is also possible that we apply it to a surgical
navigation by doing the registration of an actual object and 3D-CG model more precisely.
