When setting up, commissioning and operating the scanner, you must observe the following
safety information at all times:
1.
The device may be operated only by adequately trained staff that has knowledge concerning the
proper use of the device as well as the safety information cited here.
2.
The device is intended exclusively for use in dry, enclosed rooms.
3.
The device may be operated only on a stable base (tabletop, bench, etc.) that has a load bearing
capacity which is at least twice the net weight of the scanner as stated in the technical
specifications.
The base must be fixed to a building wall or have a braced support frame that is suitable for
absorbing vibrations occurring during operation of the scanner.
Besides the pure load-bearing capacity, the sturdiness and stability of the base is crucial for safe
operation of the scanner.
4.
The information on transport and storage must be observed when lifting and transporting the
scanner.
5.
Please do not place any objects on the scanner, as there is a risk that these can fall down owing to
the surface structure as well as the resultant vibrations during scanning operation.
6.
The "Activity 885" scanner has been developed and manufactured in accordance with the
applicable safety standards and with the greatest possible care. In spite of this, the risk of an
electric shock, overheating or fire due to technical defects in individual components cannot be
totally excluded.
You should therefore switch the device off when not using it for longer periods and when it is left
unattended. This also benefits the environment, as it means less electrical energy is consumed.
7.
The scanner contains a motion unit comprising four electrically powered axes of rotation that serve
to position the object during scanning. To enable the object to be clamped in a definite position as
well as a faster workflow during scanning, the movement axes are also kept in position electrically
when the flap is open.
7. General saftey information

An electronic protection mechanism prevents the motors from starting up unintentionally or
continuing to operate when the flap is opened.
As there is a theoretical possibility of the protection mechanism failing, this entails a residual
risk which you can counter by complying with the following rules of use:
7.1.
Do not open the front flap during a scanning procedure until after
a corresponding prompt or the end of a scanning procedure has been displayed on the
screen.
7.2.
If you determine that the scanner is acting unusually, such as an uncontrolled or continuous
rotation of one or more movement axes, switch off the scanner at the main switch before
opening the flap.
If this unusual behaviour continues after switching on again and restarting the software, do
not use the scanner any longer. The device must be marked as defective and prevented from
being put into operation again until the fault is rectified.
7.3.
Do not reach inside the scanner if one or more movement axes move despite the flap being
open. Switch the scanner off immediately.
The scanner may no longer be used in this case and must be marked as defective and
prevented from being put into operation again until the fault is rectified.
7.4.
During scanning, never reach below the area between the rocker and case that is marked by
warning signs.
This also applies if the rocker is swivelled upwards to the rear.
Before removing any objects that have fallen into the scanner or before cleaning the scanner
compartment, you must switch off the device at the main switch.
8.
If you notice that the scanner is damaged or defective, you must label it as defective and make
sure that it is not used until it has been repaired.
General saftey information
10
The net weight of the scanner is approx. 32,2 kg.
Always observe the following instructions to lift the scanner properly out of the
packaging and position it at its location of use.
Two people must lift the device out of the packaging and place it on the prepared,
intended workplace.
Be sure to transport the scanner (while still on the pallet) as closely as possible to the
workplace to avoid longer transport distances.
The scanner accessories can be found at the base of the packaging.
Check that the scope of delivery is complete.
Inspect the external packaging for visible damage as soon as you take delivery of the scanner. If you
notice that the packaging is damaged, inform the delivering forwarder and your specialist dealer
immediately.
The device is delivered in a strong outer box on a wooden pallet. After removing the straps, open the
upper folding lid of the box. The box contains a foam piece that protects the scanner, which is packed
below during transport.
First, pull the foam piece upwards out of the box. You can then lift off the whole box upwards.
Before installing the scanner, you should select a suitable installation location.
A suitable, stable base (bench, tabletop etc.) should be chosen as an installation location.
If you install the computer required for operating the scanner underneath the worktop, the available
worktop area should be at least 1.1 m x 0.75 m (front width x depth). If you plan to also place the
computer on the worktop, the area must be enlarged corresponding to the dimensions of the
computer.
The selected workplace should, if possible, face away from windows or strong artificial light, as
excessively strong external light can lead to undesirable reflections on the monitor that can interfere
with the functioning and results of the optical scanner in extreme cases.

24
Basic information about the device
If the axis calibration fails, please check the height alignment of the model in the
measuring field.
The optical scanner with the designation "Activity 880" is used for the three-dimensional measuring of
jaw models, in orthodontic and prosthetic applications.
The most important components of the scanner are the 3D sensor and the positioning unit with
object holder.
The 3D sensor consists of a camera and a projector. The projector throws a light pattern onto the
object to be measured at an oblique angle of incidence; the object is simultaneously monitored with
the camera.
Since the camera cannot capture the entire object if the object is complex in shape, as in the case of a
jaw model, the object is mapped with a series of individual scans from various perspectives.
The software then combines the individual scans to create a complete data set.
The positioning unit positions the object to be measured in the required perspectives opposite the 3D
sensor.
It contains motorized axes for this, which can rotate and tilt the model on the base relative to the 3D
sensor.
The entire scanning procedure is extensively automated so that you only have to carry out the essential
operating steps.
11. Basic information about the device
11.1 Functioning of the Activity 885
25
Basic information about the device
A 3D scan is created as follows:
The model to be measured is mounted on the object holder:
The model is fixed on the object holder for this.
Prescan:
The prescan compiles a two-dimensional image of the clamped model.
This image serves as a basis for the following scan definition.
Scan definition:
The scan definition defines the positions in which the model is to be scanned.
The scan definitions are formulated using the prescan image after the user highlights the tooth
positions on the screen.
Individual measurements:
After completing the scan definition, the software automatically calculates a scan program for
recording the positions specified by the operator and starts these. The positions provided in the scan
program are started up by the positioning unit and a 3D measurement is performed.
When scanning adjacent tooth stumps, it is usually necessary to measure the stumps in isolation
without the adjacent stumps, as otherwise the interdental area cannot be captured by the 3D sensor.
The software will therefore prompt you to present the relevant tooth stumps individually and freely, i.e.
to remove all other stumps from the saw cut model.
Matching and data storage:
The recorded individual measurements are grouped together in the "Matching" mode.
The finished data set is then saved on the hard disk of the computer.
Visualization:
When the matching process is complete, the scan result is displayed on the monitor so that you can
directly assess the result visually.
The most important components and operating controls of the scanner are explained below.

Positioning unit (inside the scanner):
The positioning unit contains the fixed base holder on which the object to be measured is fixed as well
as a rocker and a rotating unit powered by an electric motor.
Swivel axis:
The electrically driven swivel axis means that the object that is to be metered can be held in any turning
position relative to camera of the 3D sensor that is above the object slide.
The swivel unit makes it possible to swivel the whole set-up consisting of swivel unit and object slide
sideways and so capture side views of the object to be metered.
Interior lighting:
The interior lighting switches on automatically when the flap is opened. If the flap remains open for
longer than 5 minutes, the lighting will switch off automatically.
The interior lighting switches off automatically when the flap is closed.

Positioning:
The correct positioning of the model on the object holder is indispensible for correct measuring results.
The positioning must be maintained in respect to the "height alignment".
Height alignment:
The scanner has a definite height measuring range. If the object to be measured is located outside this
range, no measuring values will be measured there. This means that the finished scan will exhibit holes
or have a cut-off effect.
The scanner has a height measuring range of +/-40 mm, in other words a total of 80 mm. The middle
of the measuring range is determined using the measuring range template. (See fig. 29)
We recommend positioning the preparation margin / tooth equator at the height of the cross to
capture the jaw models in its entirety.
11.4 Positioning the model on the object holder
Basic information about the device
33
Incorrect height alignment is one of the most frequent reasons for unsatisfactory scanning
results!
Figure 28: Height alignment with measuring range template
It is not usually necessary to realign each non-articulated model in respect to height.
Since you will usually work with one model system in a laboratory, you can work with a standard
setting already defined in most cases. However, we recommend making sure that the height deviation
is not too great for each model to be scanned.
Mounting:
Fasten the required spacer plates on the base holders. When doing so, the correct screws must be used
to stabilise the setup. Last of all, position the locking plate fitted with a magnet in place. Place the
object holder being used onto this.
34
Scanning procedure
Using "zero" spacer plates:
Should it be necessary to attach a model directly to the base plate, remove the locking plate from the
spacer plates using the hex key included in delivery, and place it on the base plate.
The number of spacers laid beneath must be entered using the software (see software
description).
To set the height of the object holder, start the scanner software before the setting the height, so that
the axes move into the reference position (this occurs automatically when starting the program).
Clamp the model in the removable object holder and align the height using the spacer plates (see
Figure 28 and 29).
Depending on the scanner and CAD software combination, it is not necessary to fill out the
project information thanks to a special interface, as this is automatically undertaken by the
CAD software (e.g. with exocad
®
DentalCAD). The scanner uses software messages to
guide you step by step through the entire scanning procedure.
After starting the program by double clicking the icon "DentalDB" on your desktop, the program input
mask opens:

12.3 Case study: bridge with squeeze
36
Scanning procedure
Case example:
In the case example we scan a bridge of 24-26.
In the tooth schema, click on the teeth 24, 26 and under scan type select "reduced anatomic cap "
and 25 as "pontic reduced ".
Teeth 23 and 27 are marked as "neighbouring teeth". For 33 to 37 select "Antagonist" and under
"Antagonist type" -> "None/squeeze occlusion".
The teeth are now coloured with the respective scan type colour in the tooth schema.
Confirm the entries by pressing the "Save" button.
Switch the scanner on at the mains.
The activity software opens automatically after the "Scan" button is pressed.
The axes are then automatically referenced.
The scanner software guides you through the scan workflow based on the details in the
"DentalDB".
You will now be asked to mount the model with the squeeze occlusion and start the 2D scan.
Figure 31: "bite 2D scan"
After a few seconds, a 2D scan will appear on the viewer, and you can select your individual scan type.
37
Scanning procedure
Figure 32: "Bitescan-Preview"
Coloured squares will appear simultaneously in the preview. (See fig.33)
These squares indicate the scan area of the tooth/ squeeze occlusion. The respective colour scheme is
the same as the selected scan strategy/ scan type in the tooth schema on the left-hand side. By
pressing the left mouse button, you can slide these squares so that they centre on the respective tooth
stump/ squeeze occlusion. The scan software can now recognise the position of the tooth/squeeze
occlusion and will apply the respective scan strategy for these coordinates.
The software will indicate the next steps in the workflow
(See fig.34)

Use the spacer plate to ensure the correct height alignment in the scanner. (see Figure
28; 29 and 35).

The scanner now moves the model down automatically, based on the predefined scan strategy, and
compiles a number of individual measurements from various perspectives.
During the prescan or the 3D scan, the symbol is displayed, and you can use this to
cancel the corresponding scanning process.
After a short time the squeeze occlusion scan will appear in the 3D viewer. (See fig. 37)

Figure 38: 2D modelscan
Perform the 2D scan again and align the prescribed tooth positions, select the spacer plates and start
the 3D scan. (See fig. 33 and 35)
The prescan is started and you can then newly define the selection for the occlusion registration in the
pre-scan image.
The neighbouring teeth can also be measured for individual images. If this mode is activated by
checking the box, the neighbouring teeth will be interdentally measured individually.
If this mode is deactivated, only a global scan will be used for the neighbouring teeth.
(See fig. 40)
Figure 39: selection box Scan Type
The entire scene is therefore always measured in the first step, and in the second step you are
prompted to present one tooth each freely (see Fig. 41).
Scanning procedure
41
Figure 40: prompt notification
Remove all teeth from the saw-cut model, apart from the one required.
Close the front flap and click "Continue" or "Continue with axis homing".
If "Continue with axis homing" is selected, a new reference travel of the axes, object holder or all
axes is first executed before the measurement is continued, after removing the stumps. The object
holder is moved into the predefined initial position for this.
This selection option is due to the fact that the motor driving the object holder could also be turned by
hand when switched on with a correspondingly high action of force. The motor is not damaged by
this, but the defined motor position is lost.
It may be the case in individual situations that greater force has to be applied for very tightly-fit
stumps, and the object holder is consequently turned inadvertently. Here a considerable "slipping
through" of the object holder can be heard, so that you usually recognize such a case. Select the
option "Continue" to continue the scan.
After the individual tooth presentation is completed, you can evaluate the scan data in the 3D viewer
for completeness (see Fig. 42).
Scanning procedure

Figure 41: Data set before matching
If the model scan exhibits holes or blurred areas, you can correct these with the rescan function.
A green cross is located at the top of the 3D viewer, which can be used to start the "Rescan Mode".
(See figure. 43)
Figure 42: Rescan button
If "Rescan Mode" is enabled, this green cross will be shown in the centre of the 3D viewer (see above).
Now the edge of the data hole must be positioned below the cross using the familiar mouse options
(left mouse button rotate, right mouse button move and scroll wheel zoom).
If the centre of a hole is positioned directly below the cross, the scanner will move to an
incorrect rescan position and possibly a recording at another point.
Scanning procedure
43

If you click on the blue start button, any number of rescans can now be performed until all
desired areas are recorded.

For details, such as in interdental spaces, please remove all teeth that impair the sensor's
view of the area to be closed, e.g. directly adjacent teeth and segments that are not
required for the scan.
After completing the scan and cutting the data set to size, you need to perform a matching.
To do this, click on the following icon:
Figure 45: "matching" process
The recorded individual measurements are automatically added together by special
algorithms, and an STL is created. This process is known as matching. You can set the
quality of the STL under Item 13.4.
After matching the records, the completed data set is reloaded into the 3D viewer. If more areas are
missing, the rescan mode can be repeated on the STL data set.
To remove superfluous areas on the model, you can now cut the data set to size with the following
tool.
Cut data inside the selection
Cut data outside the selection
Undo the last cutting action
Select a cut function and click with the left mouse button around the required area. In this way, you
select the area on and around the model.
To complete the process, make the last selection with the right mouse button.
The model has been cut to size and can be reset with the "Undo cut function" icon.

The checkbox is used to activate a cut filter, which cuts the upper and/or lower area of the STL
data set. The dimensional unit is millimetres.
Base:
The STL surface details and so also the data size are determined by the scan quality.
The higher the surface details, the lower the distance between the pixels.
The maximum distance between the pixels is reproduced by selecting "Very high".
A slightly larger distance between the pixels is cross-linked to a data set by selecting "High".
This distance gets bigger by selecting "Normal" and "Low".
The highest precision is achieved by selecting the scan quality "Very high".

If sporadic "data holes" appear after a scan, you can close these
using the “Fill holes" function. The size of the hole to be closed is limited upwards by entering
the area in mm

. We recommend that you use this function for flat surfaces only. Incomplete
areas at preparation limits or sharp, occlusal edges should not be extended by this, as the area
to be replaced is only interpolated.
Fill large holes
If you activate the checkbox, the object will be displayed in the 3D viewer at an even higher
resolution. The object calculation when adding new records as well as during movements
requires much greater capacity from the graphics card and can lead to time delays.

You can use this function to define whether matching is to be made to the existing STL or to
the existing individual images. The query is only set for an existing STL.
Prompt for matching on raw scan data
Existing individual images are again used to create STLs also for re-scans and additional scans
and an already existing STL is not used for the calculation as a matter of principle.
Always match scan data
The existing individual images are automatically deleted irrevocably when the program closes.
Automatically change to re-scan after each individual tooth presentation
The re-scan mode is started after each individual tooth presentation when this function is
activated. This function should only be used in complex cases.
Always delete scan data on program exit
Here you can choose whether the STL file of the individual image is to be cropped first. We
recommend cropping the STLs first.

Maintenance and servicing
14. Maintenance and servicing
The axes should be calibrated every four weeks using the calibration model supplied to ensure
consistently good results. They should also be calibrated each time the device is transported. We also
recommend performing an axis calibration at temperature fluctuations of +/- 15 °C.
The scanner should be cleaned regularly when in service. To do this, turn the scanner off and use a
vacuum cleaner to carefully remove any dust and foreign objects that have accumulated in the base
area of the scanner.
The optics of the 3D sensor are situated in the upper area of the interior of the scanner. Do not attempt
to clean them, as inappropriate cleaning may result in damage.
Cleaning with a slightly damp microfibre cloth is sufficient in most cases. Do not use paper towels, etc.,
if at all possible, as they can easily scratch the sensitive plastic surfaces.
Please do not treat the case with strong cleaning agents.
Please remember that the scanner is a sensitive optical device. Maintenance and repair may therefore
be performed only by trained technicians.
Faults that cannot be cleared by restarting the scanner or the program should be referred to customer
service.
You can return the packaging to your dealer for disposal.
We strongly recommend that you keep the packaging so that it can be used if you need to transport
the scanner or if you have to return the scanner to us in the event of a warranty claim.
You can return the scanner to the manufacturer or dealer for disposal.
Please remember that the scanner is designed exclusively for commercial or industrial use.
It must therefore not be taken to public waste facilities for disposal.
Please contact your dealer or the manufacturer regarding disposal.
