Page 25: Basic Information About The Device
11. Basic information about the device 11.1 Functioning of the Activity 850 The optical scanner with the designation "Activity 850" 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 26 Basic information about the device 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.

Page 38: Figure 38: Starting The Scan Process
Scanning procedure After aligning all scan positions, start the 3D scan with this icon. Figure 38: Starting the scan process The scanner now moves the model down automatically, based on the predefined scan strategy, and compiles a number of individual measurements from various perspectives. In the case of adjacent teeth, it is necessary to additionally measure the individual teeth independently, as otherwise the interdental area cannot be recorded with sufficient accuracy. -
Page 39: Figure 40: Data Set Before "Matching
Scanning procedure 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. -
Page 40: Figure 41: "Rescan" Mode
Scanning procedure 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. -
Page 41: Figure 43: Save Project
Scanning procedure 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. -
Page 42: Figure 44: "Matching" Process
