Removable handle scan body for impression trays and radiographic templates for integrated optical and CT scanning

摘要

A device for use in optical scanning and CT scanning including a radiographic template and at least one shape of known dimension (SKD). The radiographic template includes a plurality of radio-opaque markers and is configured to take an impression of at least one surface of a patient. The SKD is removably attached to the radiographic template and serves as a basis for registration of data of a CT scan of the device with data of an optical scan of the device. The device may further comprise a mounting plate. The SKD is mounted on the mounting plate such that the at least one SKD is in an exact same position with respect to surfaces in a model formed from the impression as when the impression of the patient is formed in the radiographic template.
