Simplant® CBCT to Simplant® - Export protocol for Newtom VGi 5G This protocol gives a detailed description of the steps to be followed for exporting your NewTom VGi/5G scan images, with NNT software V3.00 or above, in DICOM format and for importing these in Simplant. This protocol aims at an optimal visualization of your images in Simplant but does not guarantee easy segmentation. Part 1: NNT software V3.00 or above 1. Scan the Patient (as provided by NewTom) a. Select the FOV: For implant dentistry, [12x8] FOV (in case there is no metal in the mouth, such as implants and large amalgam fillings) or [8x8] FOV is recommended. b. Positioning the patient: Position the patient in such a way that he/she is symmetrically positioned and the volume of interest is centred in the FOV. This is achieved by manually repositioning the patient’s head and by performing a check via scout flash images. Note: When a scan prosthesis is applied during the scan, make sure the prosthesis is separated from the opposing arch by a radiologically transparent bite -block. c. Taking the scan and process the dataset Perform the patient acquisition by selecting the “Patient scan” procedure. This will result in a dataset of axial images (Volumetric data) with an isotropic voxel. i. Creating a Study Create a Study from the Volumetric data. By creating the Study, you can crop unnecessary portions and limit it to the volume of interest. In the process, the orientation of the patient’s head can also be finely adjusted in terms of symmetry and orthogonality. Select ISO (isometric voxel).
