12 Planning without CT scan

Blue Sky Plan® software also allows planning for cases without a CT scan – STL models only. If a user plans a case without a CT scan, the imported models might not be oriented properly (the orientation does not match the head in the bottom left of the 3D view). This makes planning very difficult. For these cases, Blue Sky Plan has a model alignment dialog, which opens when selecting the planning type of the "Surgical Plan with Optical Scan".

You can import one or several models. For alignment, it is necessary to select the primary model (ideally Maxilla) through which the alignment is done. The user also needs to specify if the model is a Dentated Arch, an Edentulous Arch or a Partial Arch.

In the next step, the user marks three points on the model (by holding Shift + Left clicking the mouse) to help the software align the models properly (to match the orientation of the BSP coordinate system). The rest of the models will be aligned relative to the alignment of the primary model.

In the last step, the user can manually fine-tune the primary model using the grid. If several models were imported, they will move together as a group.

Blue Sky Plan® software also allows the user to align models automatically. This option can be modified in Preferences.

The primary model can be manually adjusted using the grid. If several models were imported, they will move together as a group. It is possible to reset the position of the fine-tuned model to its automatically aligned position. STL model alignment will be completed by clicking the "Finish" button.
