1.
Definition
Curve is a 3-dimensional user defined curved or straight line in 3D Pane and MPR
Pane. In EzImplant, the user sets the path along which is generated continual 2D
cross section according to the selected start/finish points and view direction. Also,
with [Select Latest Item] function, the user can easily find all Curves made
previously.

(1)
Curve / Cross-Sectional
How to make Cross-Sectional View
In dental image, the direction of each tooth changes according which part you
see the arch. Therefore in dental area, generally analyzes teeth by making
Cross-Sectional View. To make Cross-Sectional View of arch is divided into 2
type; Full arch and partial arch.
58
▪ Partial Arch
It is important firstly to determine the correct orientation of the Occlusal Plane and
teeth and to adjust the axes to match the desired planes.
Firstly, adjust the X-axis (Coronal) to run parallel with arch in [Axial] Pane.
In [Axial] Pane, the X-axis (Coronal) is rotated parallel to the arch.
Move the X-axis over to the arch by dragging the interior part of the axis.
The image in [Coronal] Pane is converted into Panoramic image. To analyze the
entire arch, Rotate X-axis (Axial) parallel to Occlusal plane and to analyze a single
tooth Rotate X-axis (Axial) as parallel to the tooth.
59
For precise arch settings, move X-axis (Axial) to the roots on [Coronal] Pane.
Having defined the planes accurately, on the Main Tool, click [Task] → ‘Curve’ →
‘Cross-Sectional’ then go to [Axial] Pane and click the middle of the arch to set the
line. Finish drawing line by Double-clicking the mouse.
★ Note: It is recommend not to click numerous points when drawing the line. As
you will notice by practicing, fewer points generates a more natural curve line.
60
▪ Full Arch
Rotate X-axis (Axial) on [Coronal] Pane so as to parallel the Occlusal Plane.
Rotate X-axis (Axial) on [Sagittal] Pane so as to parallel the Occlusal Plane.
Then move X-axis (Axial) to the plane of the roots.
The 3D image helps to define the Occlusal Plane and this can be easily adjusted.
61
Click [Task] → ‘Curve’ → Cross-Sectional on Main Tool and go to [Axial] Pane.
Click points on the middle of the arch to set curved line. Finish drawing line by
Double clicking the mouse.
(2)
How to understand the Cross-Sectional View
Cross-Sectional Pane is composed of [Cross-Sectional View], [Axial View],
[Panoramic View] and [3D View]. You can confirm the exact location of points
located in [Cross-Sectional View] and [Panoramic View] via [Axial View]. And
with [3D View] you can find out the location more intuitively.
▪ Cross-Sectional View
Cross-Sectional View displays the perpendicular section of the arch continuously.
The structure of Cross-Sectional View is as shown below. In each frame in the Pane
the ruler indicates the real size. In [Cross-Sectional View], as the image’s right-left
orientation is subject to change according the part of the arch displayed, the
direction is inmdicated as L(Lingual) and B(Buccal).

Understanding & Application for MPR image
MPR (Multi Planar Reconstruction) provides the function that makes possible to see
selected sectional images by Anterior, Lateral and Horizontal planes as crosssectional images which are reconstructed from captured Z-axis data.
In the diagram above, Yellow is vertical section in the Anterior plane and describes
the “Coronal View”, Red is vertical section in the Lateral plane and describes the
“Sagittal View” and Blue is vertical section in the Horizontal plane and describes the
“Axial View”. By moving the 3 axes which correlate to the 3 vertical sections, you can
view structures in any position.
In Dental diagnosis, as the Dental Arch is the object to observe, correlation to ‘Front’
and ‘Lateral’ is subjected to change according the position along the arch. Therefore
CT (Computerized Tomography) in Dental uses Cross-Sectional Views and multi
planar econstructed images (MPR) as a practical tool to analyze the continually
varying plane of the arch.
Application for Dental CT image is generally divided into Maxillary and Mandible use.
For Maxillary, distance to Sinus and the existence of Sinus outer wall are the
important factor to reduce failure in Bone Graft surgery. And for Mandible, CT
imaging is applied to check the distance to neural tube and to confirm where the
neural tube is sited.
121
Appendix
2. Application for 3D image
3D image is a reconstructed image using Volume Rendering techniques.
(1)
MPR Plane Image
When you click an axis in MPR, the vertical section of the selected axis is also marked
in 3D image in overlay form so that you can easily confirm the position.
(2)
State of Bones
Adjustment of the Opacity Graph with “Fine Tuning” function allows checking of the
state of bones, especially bones of teeth. This is very useful to obtain the patient’s
agreement in medical treatment.
122
Appendix
(3)
Review Treatment Result
With 3D Zoom function more confident and efficient surgery or treatment is possible
as the user can view the state of bones in great detail inside. Also, when a patient
complains of unknown pain after implant surgery or neural treatment, Cube Zoom
function makes it possible to find a subtle cause for post treatment faster.
The image below shows bone absorption because of wrong neural treatment.
3. 3D image and CT No.
(1)
The relation between 3D image and CT No.(Hounsfield Unit, HU)
When you click “Fine Tuning” on the bottom, the Fine Tuning window appears. In
above image, values shown equate to CT numbers. CT number, also called as
Hounsfield Unit(HU), has the range of density from -1000 to +1000 and it is set
relatively according the standard value of AIR(-1,000), WATER(0) and hard bone as
CROWN(+1,000). For example, in above Fine Tuning window, only data with more
than -19.3 values will be reconstructed as D image and if you want to change the
value click and drag the ladder like Graph. When you click and drag the Graph’s outer
region with mouse right button, the range of “Fine Tuning” is extended or reduced.
123
Appendix
★ Note: when you click and drag the Graph’s outer region with mouse left button,
you can see the Graph is moving on range extended view.

The relation between 3D image and Color bar
The Color bar is for changing the 3D image’s color and it’s helpful to give different
color on each image and as a rough indication of density. The Blue outline above
indicates the Color bar with anchors inside you can adjust colors. For example, less
than -19.3 value is showed in Red color and more than 162 is showed in White color.
The middle value is subjected to show a middle color between Red and White. And if
you click and drag the dots valued 162 right to left, you can see the change on color
bar and 3D image.
