    10. Basic information about the device 11.1 Functioning of the Activity850/Activity855 The optical scanner with the designation "Activity 850/Activity855" 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.
  • Page 28 The entire scanning procedure is extensively automated so that you only have to carry out the essential operating steps. 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.

    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 rotating and swivelling unit powered by an electric motor. Rotating and swivelling unit/Object holder: The rotating unit allows you to position the object to be measured in any position relevant to the camera of the 3D sensor located on the object holder via the electric motor.
  • Page 33 This clamp is fastened or released using the hex key (4). Using the object holder system: The object holder of the Activity 850 primarily comprises a system base plate fixed on a rotating- swivelling unit.
  • Page 34 System base plate Figure 34: Object holder system In order to ensure an optimum alignment of the model to be scanned in the measuring range, a maximum of one additional spacer plate can be mounted on this. The object holder can now be fixed on the base or spacer plate. Example: Standard model holder without spacer plate Figure 35: Object holder system with model...

  • Page 35: Positioning The Model On The Object Holder

    11.4 Positioning the model on the object holder 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.

  • Page 36: Scanning Procedure

    The height alignment can be checked using the measuring range template of Activity850. To do this, place the template on the rotating and swivelling unit and check the height in the cross hairs with the jaw model. Activity 855: Due to its large measuring range an additional distance plate is not required.
  • Page 37 Switch the scanner on at the mains switch. The scan software opens after starting by double clicking on the "Activity" icon on your Desktop. An automatic referencing of the axes takes place. The project entry screen appears: Figure 37: "New project" Information such as laboratory, dental technician, patient, etc.
  • Page 38 After providing a name for the measurement, confirm this with "OK". The scanner then begins with a preview image. After a few seconds, a 2D scan will appear on the viewer, and you can select your individual scan type. During the prescan or the 3D scan, the symbol is displayed, and you can use this to cancel the corresponding scanning process.

Figure 41: Data set before "matching" You can rotate, move and zoom the model using the following mouse functions: Rotate model Left/Right mouse button Move model Both mouse buttons Zoom Scroll wheel 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".
  • Page 42 Cross hairs next to the area to be scanned Area to undergo a rescan Figure 42: "Rescan" mode Figure 43: "Rescan" If you click on the blue start button, any number of rescans can now be performed until all desired areas are recorded.
  • Page 43 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. Once you have recorded all relevant details, click on the green cross again to complete the rescan mode.
  • Page 44 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 10.4. 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.
  • Page 45 Figure 50: Information window Confirm with "Yes", and the device will immediately commence with the 3D scan based on the selection created in the main scan (see Fig. 50). After confirming the message with "No" , the prescan is started and you can then newly define the selection for the bite registration in the prescan image (see Fig.
  • Page 46 Figure 48: Cut bite registration After completing the 3D scan, you can evaluate the result and, if necessary, perform rescans, or cut to size with the cutting tool described above. Save the change and start the matching process. The matching button for a bite registration scan is not enabled unless the model data set has been matched previously.

  • Page 47: Case Study: Complete Jaw Scan

    12.4 Case study: complete jaw scan Clamp the model on the removable object holder. Ensure the height alignment in the measuring range. (See Fig. 37). For certain applications, e.g. archiving in orthodontics, it is necessary to simply and quickly scan a complete jaw. Unless high detail accuracy is required for this, we recommend setting the thinning to MEDIUM or STRONG.
  • Page 48 A new control (blue line) is shown in the prescan view: shift move Figure 51: Complete jaw alignment prescan The scan range is adapted to the size of the object to be scanned using the yellow checkpoints. The jaw must be inside the blue outline, the scan range. Start the 3D scan.
  • Page 49 Figure 53: Complete jaw 3D scan After the 3D scan, cut the data set if necessary. Now start the STL calculation with the Matching button. The matching process for a complete jaw can take up to several minutes, irrespective of the number and size of the scans to be matched or the selected thinning level and computer capacity.

    You can tell from the colouring of the file tab whether a data set is already "matched", i.e. whether there is an STL. (Blue - individual records, Yellow - STL data set, Grey - 2D scan) (see Fig. 59) Figure 55 : Tabs 12.5 Case study: occlusion scan You can also scan a jaw pair in occlusion.
  • Page 51 As soon as you have scanned in the lower and uppers jaw, you must perform a "vestibular scan", which allows the software to calculate how the jaw halves are located relative to one another. The scanned jaws do not have to be matched, as all scans performed are added together at the end of the process.
  • Page 52 Figure 58: New measurement Once the prescan has been performed, click on "Antagonist Alignment" in the left of the project entry screen, after which you can select what method is to be used to perform the vestibular scan. Figure 59: Antagonist Alignment A blue outline will appear in the 2D image after clicking on "Antagonist Alignment".
