Blue Sky Plan Manual

The STL model imported to BSP may contain excess material and printing it would mean an unnecessary waste of printing material. For these situations, BSP offers the trimming function by means of a curve. The trimming curve is created automatically at a distance from the teeth based on the "Gingiva Trim Margin" parameter (which can be modified in Preferences). The curve is further manually adjustable by dragging the control points. Part of this step is also the closure and trimming of the model at a specific height based on the distance of the segmented teeth. The parameters "Model Height Below Mandible Teeth After Trimming" for the lower jaw and "Model Height Above Maxillary Teeth After Trimming" for the upper jaw can be modified in Preferences. The Model Trimming step can be skipped by using the options "Don't Trim Maxilla" or "Don't Trim Mandible".

In this step, Model Trimming is only defined. It will only start after clicking on Continue to Teeth Moving, so this operation may take a while. After the separation of the teeth, the gingiva may be augmented (i.e. inflated) to prevent interference with the aligner and to help prevent tissue impingement. Note: Due to the optimisation in the processes, the .0mm value is recommended for versions 4.7.50 and higher. The .2mm is recommended for versions 4.7.20 and older. This is the "Gingiva Augmentation Amount" parameter in Preferences. Also, the colours of the 3D model and the teeth change to a more natural pink and white, respectively. Now the software allows you to reposition the teeth and plan their final positions.
