Abstract
A method and system for the fabrication of dental articles includes at least two imaging and measuring devices, which measure and provide images of the internal and external structure of intra-oral objects in a patient's oral cavity. The outputs from these devices are linked so that the descriptions of the intra-oral objects and features, oral cavity and surrounding bone structure are stored in a system of reference positions. The system of reference positions functions as a 'global positioning device' registering locations and orientations of the measuring and imaging device or probe relative to the intra-oral objects and bone structure and orientations of the resulting individual frames or scans in the global system of coordinates. Three-dimensional images, scans and/or maps of the oral cavity obtained from each device are pieced together to generate solid three-dimensional models of the intra-oral objects.
