摘要： The present disclosure relates to a dental scanning system for acquiring scan data of a physical three-dimensional dental object during a scanning session. The dental scanning system comprises a scanning device and a first processing device for generating a 3D model. The dental scanning system may further comprise one or more second processing devices for rendering and/or displaying the 3D model. The dental scanning system is preferably suitable for continuously acquiring, processing, and transmitting images such that a video is streamed during the scanning session. The disclosure further relates to methods related to e.g. transmitting digital images in real-time during a scanning session to one or more external processing devices, and methods for generating a digital three-dimensional (3D) model of a dental object and displaying said 3D model remotely in realtime.
