Intraoral scanning system and method for using remote resources

The intraoral scanning system includes an intraoral scanning device configured to acquire light information reflected from a dental object and further includes one or more processors connected to the intraoral scanning device. The one or more processors are configured to determine, in real time, surface information from the light information, and generate a three-dimensional surface model of a dental object using the surface information. One or more remote computers includes a resource pool, wherein the system provides temporary access for the intraoral scanning device to one or more resources of the resource pool based on a predefined performance mode of the scanning session. Each of at least two predefined performance modes is configured to operate the intraoral scanning device with a different number of resources from the resource pool and/or with a different type of resources from the resource pool.
