1 FACAD TRACING - IntroductionFacad is a software program used
for orthodontic tracing, cephalometric analysis, andvisual
diagnostic imaging, as well as for treatment planning with soft
tissue profileprediction for both orthodontics and maxillo-facial
surgery. This program is meant to beused by orthodontists and
orthofacial surgeons.
Facad Tracing is a limited version for orthodontics, which does
not include thefunctionality for treatment planning and soft tissue
profile prediction. This tutorialdescribes the functionality for
the limited Facad Tracing version.

Facad Tracing 3.5 - Tutorial4
3 Open a Facad patientYou need to open a Facad patient, before
you can start working with a patient's image(s).You can open a
Facad patient using several methods:
Open an existing patient using the Patients List, see section
3.1 below Open a patient using one of the built-in plugin programs,
see section 3.2 below Create a new patient and import images
manually, see section 3.3 below
3.1 Open an existing patient using the Patients ListThe
Patients/Work List opens automatically when the Facad program is
started.If you want to open the Patients/Work List manually:
Standard menu: File>Patients/Work ListKeyboard key: L
Tool button:The Patients/Work List contains 2 lists, the
Patients List and the Work List.
Tab: Patients ListThe Patients List presents existing Facad
patients.
Tab: Work ListThe Work List presents new patients and new images
that have been transferred to Facadusing one of the built-in plugin
programs.
Open an existing patientSelect the patient you want to open from
the Patients List and click Open, or double-clickon the patient.
When a patient is opened, the patients Image/Tracing Manager
isdisplayed.
3.2 Open a patient using one of the built-in plugin programsThe
built-in plugin programs are used to transfer digital images and
patient data from x-raysoftware, PACS, or patient management system
to Facad. Examples on software than canwork with Facad are:
CliniView, DBSWIN, DentalEye, Digora, Dimaxis/Romexis,
Edward,Sectra PACS IDS5/IDS7, Sidexis, VisiQuick, VixWin.
Standard menu: Help>Facad Manuals>Plugin program
Guides>...Information on how to set up the different plugin
programs is found in the Help menu.You may also contact your Facad
dealer for help in this matter.
Some plugin programs opens the Facad patient (existing or new)
automatically, while otherplugin programs makes incoming
patients/images available in the Work List.

Facad Tracing 3.5 - Tutorial5
Open a patient from the Work ListSelect the patient you want to
work with from the Work List and click Open, or double-clickon the
patient. When a patient is opened, the patients Image/Tracing
Manager isdisplayed.
3.3 Create a new patient and import images manuallyLet us assume
that you have a digital x-ray image file (JPEG, TIFF, BMP, or in
DICOMformat) on the computer, a USB memory stick, or on a CD, and
no Facad plugin programis used to transfer the image to Facad.For
instance, the x-ray image file is a scanned x-ray film.
In this situation, the Patients/Work List is not used at all.
Close the Patients/Work List if it isopen.
Standard menu: File>New PatientKeyboard key: N
Tool button:Displays the New patient dialogue box.
Enter the patients unique ID, first name, lastname, and other
relevant patient data in theappropriate fields, and click
Create.This will automatically create a new patientfolder in the
Patient Data Node folder, and anew Facad file is automatically
saved in thisnew patient folder.The patients (empty) Image/Tracing
Manager isthen displayed.
If you are going to import a DICOM image file, use Import Dicom
image and import theimage before you enter any patient data. The
patient data will then be enteredautomatically using the
information stored in the DICOM image file.
3.3.1 Import an image to the patientTo import a new image, click
on Import image in the Image/Tracing Manager. Browse and locate the
image file. When the image is chosen, the Image Informationdialogue
box is displayed.
In this dialogue box: Specify the Image Type and when the
image was Created. Only when applicable: If the image is an
x-ray image, and if you are using yourstandard scale setting as
calibrationmethod - select Use standard scale tocalibrate the
image.
Click Save. The image file is now copied into the
patient folder.
Paste an image from the Windows clipboardIt is also possible to
paste an image from the Windows clipboard, to the patient. First,
youneed to copy an image from another software to the Windows
clipboard.
Standard menu: Edit>Paste

Facad Tracing 3.5 - Tutorial6
4 Create a new TracingThe image/tracing manager is used to
manage the patients images and tracings. Every Facad patient
contains one or several tracings. A specific tracing can represent
e.g.a pre-treatment tracing, or a post-treatment follow-up tracing.
A tracing can also representa combination of several tracings, a
so-called superimposition.
The middle area of the image/tracing manager is called the Image
overview and containsall the patients digital images, shown as
image thumbnails.The right-most area of the image/tracing manager
is called the Tracing overview andcontains the patients tracings,
shown as tracing thumbnails.
To create a new tracing, first select an image thumbnail
(usually a lateral x-ray image) inthe image overview as the tracing
image, and then click New Tracing.A new tracing named Tracing # is
now created. This new tracing is automatically selectedin the
tracing overview and information about the tracing is presented in
the tracinginformation area (the left-most area of the
image/tracing manager).
4.1 Tracing informationIn the tracing information area (the
left-most area of the image/tracing manager):
1. Enter a more appropriate name that better describes the
tracing, forexample Pretreatment.
2. Select the cephalometric analysis that you want to use in
this tracing,for example BergenShort.
3. To change to another analysis, click Load and select an
analysisamong standard analyses that come with Facad, or local,
customdesigned analyses.
4.2 Open tracingTo start working with this new tracing, you need
to open the tracing. Double-click on thetracing thumbnail in the
tracing overview. The analysis window and the tracing image willbe
displayed, and you are now ready to start working with the
tracing.
Note! If you double-click on the image thumbnail in the image
overview (middle area) instead,this image will be shown in the
image viewer (display only) instead of opening the tracing.If this
happens, just close the image and you will be in the image/tracing
manager again.
4.3 SMART TIP Quick startIf you are in a hurry and you know that
the correct cephalometric analysis is previouslychosen, you can
first select an image thumbnail in the image overview as the
tracingimage, and then press the -key twice on the keyboard. This
will first create thenew tracing, and then the tracing will be
opened.

Facad Tracing 3.5 - Tutorial9
8 Calibrate the tracing imageTo be able to make correct distance
measurements in mm, the tracing image must becalibrated. If the
image is not calibrated, you need to calibrate the image.
To ensure high accuracy in distance measurements, use the Zoom
tool (before calibrating)to enlarge the image so that the x-ray
system ruler becomes as large as possible.
Standard menu: Tools>CalibrateTool button:
Starts the Calibrate tool and displays the Calibration Method
dialogue box.
The current calibration status is shown in the upper-most part
of this dialogue box.
Calibrate by measuring a well-defined distance in the tracing
image, on the x-ray system ruler (real world) which is the method
we recommend.
Select the appropriate choice in the Calibration Method dialogue
box and then clickCalibrate.
Click at two points in the tracing image that define a
well-defined distance and enterthe length (in mm) of that
distance.
You can also calibrate by measuring a well-defined distance in
the tracing imagethat is a certain distance you have measured on
the x-ray film. If known, you canspecify the enlargement
factor.
Or you can calibrate by using the image scanner's DPI (dots per
inch) setting (if the tracing image comes from a scanned x-ray
film). If known, you can specifythe enlargement factor.
Or you can calibrate by using your standard calibration
setting.
To save a certain calibration value as standardIf the button
Save as standard is clicked, the calibration value is saved as the
standardcalibration value, to simplify further image
calibrations.

which alignment method that is going to be used, in order to
geometrically
align the included tracings.Movement by one marker and rotation
by a line (recommended)Facad will place all tracings so that the
reference marker (for example S) matchesin all tracings. The
tracings will then be rotated according to the reference line
(forexample NSL) so that the reference line is parallel in all
tracings.No scaling of the tracings will be done, so it is
important that the tracing images inthe included tracings are
