A temporary alignment system and method for holding a dental coping to an implant abutment using the same threads in the abutment that are used for definitive attachment are disclosed. The disclosed temporary fasteners initially orient and hold a coping against an abutment with a force along the same axis as the semi-definitive screw. The aligned coping can be picked-up in a closed-tray impression process without unscrewing the temporary fastener. Embodiments include threaded posts that release copings from the abutment through axial forces. Some embodiments include a threaded post with separable cap that is picked-up with the coping. Methods for converting an existing prosthesis for screw attachment to implants in a single visit and digital capture of the converted prosthesis are described.

An intraoral scanner according to an embodiment of the present disclosure includes: a camera module comprising at least one camera; a communication unit including a first communication module configured to perform wireless communication in a first frequency band, and a second communication module configured to perform wireless communication in a second frequency band; and a processor configured to execute at least one instruction. In addition, the processor is further configured to obtain image data corresponding to at least one image obtained by the at least one camera, perform control such that the image data is transmitted to an external electronic device through the first communication module performing wireless communication in the first frequency band, and perform control such that control signals related to at least one of operations of obtaining transmitting the at least one image are transmitted to and received from the external electronic device through the second communication module performing wireless communication in the second frequency band.

An intraoral imaging device comprises a base and a removable probe coupled to the base. The base comprises a processing device configured to control operation of the intraoral imaging device and a first connector at a distal end of the base. The removable probe comprises one or more structured light projectors configured to project a light pattern, a plurality of cameras configured to image the projected light pattern to produce intraoral image data, and a second connector at a first end of the removable probe. The second connector mates with the first connector to provide a power connection between the removable probe and the base and a data connection between the removable probe and the base.
