## Indications for use
PC/MAC version: The RealGUIDE software is intended for the following uses: 1. Support to the diagnosis for trained professionals. The input DICOM files acquired by a CT/CBCT scanner are not modified in any way but they are showed to the doctor through the classical imaging and volume rendering techniques. It is a stand-alone product. No information of the patient is modified, all the parameters used for the image processing are read from the DICOM file itself. Neither automatic diagnosis is made, nor automatic disease detection is performed. This software is not connected to any medical instrumentation and it doesn’t control any medical or energy supplying device. The user imports DICOM data coming from any CT/CBCT imaging device and the software enables him to view the Patient exam in different multi-planar 2D images and easily reconstruct the 3D volume for an immediate visualization of bone structures and surrounding tissues. 2. Virtual oral and maxillofacial surgery planning. Doctors can plan virtual implants and surgeries on 2D/3D reconstructions and export the projects in open or proprietary format for further processing. The user can choose different implant models (for example dental implants models) from a library provided by the Manufacturers and simulate the positioning in the Patient reconstructed volume (this operation is called “virtual plan”) 3. Dental/maxillofacial surgical guides and prosthetic modelling. The virtual plan is used to design a surgical guide that is used by the doctor to drive the surgery drills according to the planned implants direction and depth. This surgical guide can be manufactured by any 3D printer working from STL files. The user can also design the patient prosthesis (typically a denture) with the surface and volume free-form tools implemented in the software. The result is exported in STL format for 3D printing or CAD/CAM technologies. Mobile version: The RealGUIDE software APP is intended for the following uses: 1. Projects visualization and editing. The input PROJECT files, pre-processed with the RealGUIDE desktop version, are used by trained professionals to evaluate the implants projects, edit them and share them with other colleagues through the cloud, as well as for a more effective Patient treatment communication. The RealGUIDE APP version is NOT INTENDED for managing a 3D diagnosis starting from DICOM images, due to the mobile devices screen resolution limitations. For this reason, the APP is not reading directly the DICOM files but only pre-processed project files, exported through the cloud by the RealGUIDE desktop version.
