Blue Sky Plan Manual

The Blue Sky Plan® Scanning Protocol calls for two CT scans. The first scan should be of the patient wearing a Scan Appliance, and the second scan should be of just the Scan Appliance. Since the Scan Appliance is made of mostly radiolucent material, the Scan Appliance does not appear in the patient's scan. It does however appear when scanned alone, since the relevant density of the Scan Appliance is greater than the density of air, causing it to appear in the scan. The software allows the two scans to be merged so the Scan Appliance can appear in the patient's scan. Merging the Scan Appliance is an aid for proper treatment planning as it shows the position of the future teeth and removes any artifacts which may have previously appeared in the area of the teeth.

Follow the steps below to import the Scan Appliance: 1) Load the patient's DICOM set into the Blue Sky Plan application. 2) In the "Model Master" module, choose "File > Import DICOMS > Scan Appliance". Follow the prompts to identify the location of the Scan Appliance DICOMs and select the relevant region of interest, selecting only the range containing the Scan Appliance.

Scan Appliance can also be imported via the "Model Master" module on the main screen. After choosing "Model Master > Import Patient CT Scan", follow the prompts and select the regions of interest (as described above). After that, the window with various types of additional surfaces appears. Choose "Import CT Scan of Denture or Scan Appliance with Markers".
