27.1 Loading the Input STL Model

The planning starts by loading the STL jaw model using the menu selection "Import Models" and choosing the correct orientation. It is also possible to use the option "Import Patient CT Scan", with the stepwise uploading of CT data and jaw models. The alignment of the STL model and the CT scan is done via "Matching Teeth", and the STL model can then be further worked with. If the other jaw (the opposing arch) is available, it can be imported in this step. After it has uploaded, the user is able to show/hide this other model together with the "Collisions" and "Closeness" functions, switching on the colour visualization of collisions as the teeth approach each other or collide. Both jaws should be automatically aligned, or it is possible to activate the model alignment widget to allow the user to move the jaw manually in the 3D view. Another function for this purpose is "buccal bite registration" (see chapter 27.2).

Import Models and Import Patient CT Scan options in the Orthodontics Module in Blue Sky Plan

Blue Sky Plan also permits the processing and planning of both jaws in a single case. This requires uploading and aligning both models in the import stage. This step further includes entering the patient's name. If there is a missing tooth in the STL model, the user is able to add a tooth via the "Add Tooth" button. By clicking the option, the Add Tooth dialog appears and it is possible to choose a tooth from several teeth geometry sets. After the tooth selection, simply click on the OK button and left click on the model with missing tooth. It is possible to adjust the tooth position or remove the tooth by right clicking the mouse > Remove. Note: Teeth can be added/removed only in the import step. The selected tooth must match the correct jaw!

Merged teeth in the segmentation step in the Orthodontics Module in Blue Sky Plan

It is possible to automatically run the steps "Annotation", "Segmentation", "Trimming", and, if CT data are available, also to align STL models to CT data. If enabled in Preferences, all the selected steps will be skipped and the user will get to the "Teeth Moving" or "Continue to Add Brackets" steps faster. All skipped steps can be returned to using the "Back" button. If the automatic function for the steps is disabled, proceed to the next step by clicking the "Continue to Jaw Alignment" button.
