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.

The present disclosure provides methods, computing device readable medium, devices, and systems that utilize a cheek retractor and/or a mobile device holder for case assessment and/or dental treatments. One cheek retractor includes a first and a second lip holder, both including imaging markers of a predetermined size to determine a scale of teeth of a user, where each imaging marker is located a predefined distance from the remaining imaging markers, and where the lip holder is to hold a cheek away from a mouth of a user to expose teeth of the user. A mobile device holder can include elements to receive a mobile device to capture images of the patient's teeth.

Interproximal reduction guides apparatuses and methods of making and using them are described herein. These interproximal reduction guides apparatuses may include a body that fits over the patient's dental arch and one or more guide slots formed in them configured to limit the motion of an interproximal reduction cutting tool in a defined manner.

The present invention relates to a combined model scanning and oral cavity scanning apparatus. The combined model scanning and oral cavity scanning apparatus includes an optical three-dimensional measurement unit configured to generate light, acquire intraoral shape information, and acquire model shape information, a data processor configured to generate three-dimensional tooth data, a data transmission unit configured to transmit the three-dimensional tooth data, a main body accommodating the optical three-dimensional measurement unit, the data processor, and the data transmission unit, and at least two intraoral scanning tips configured to be alternately detachable to the main body and provide light paths, wherein the at least two intraoral scanning tips includes a model scanning tip for scanning a dental model.

Methods and systems for taking images of a patient's teeth for tracking a progress of an orthodontic procedure. The methods and systems include a mobile device holder with one or more adjustable stops for providing a compressive force on a mobile device placed therein; a cheek retractor coupled to the mobile device holder; and a user interface on the mobile device indicating whether the mobile device holder is in a correct position relative to the patient's teeth as the mobile device holder is moved while the cheek retractor engages a cheek of the patient to expose the patient's teeth, while taking one or more visual images of the exposed teeth using a camera of the mobile device.

The present disclosure provides methods, computing device readable medium, devices, and systems that utilize a cheek retractor and/or a mobile device holder for case assessment and/or dental treatments. One cheek retractor includes a first and a second lip holder, both including imaging markers of a predetermined size to determine a scale of teeth of a user, where each imaging marker is located a predefined distance from the remaining imaging markers, and where the lip holder is to hold a cheek away from a mouth of a user to expose teeth of the user. A mobile device holder can include elements to receive a mobile device to capture images of the patient's teeth.

Provided is a dental image acquisition apparatus that allows for acquisition of images in a plurality of imaging directions with a single captured image. The dental image acquisition apparatus includes an oral cavity insertion section and an image acquisition section. The oral cavity insertion section is inserted into an oral cavity. The image acquisition section has a light source. The oral cavity insertion section has an imaging unit that includes an imaging section and a light reflection section. The light reflection section is placed at a position opposed to the imaging section via an imaging target. Also, the dental image acquisition apparatus can further include an image processing section and an image display section. The image processing section calculates three-dimensional coordinates of the imaging target on the basis of the image acquired by the image acquisition section. The image display section displays a three-dimensional image created on the basis of the three-dimensional coordinates calculated by the image processing section.

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.

The present invention relates to a combined model scanning and oral cavity scanning apparatus. The combined model scanning and oral cavity scanning apparatus includes an optical three-dimensional measurement unit configured to generate light, acquire intraoral shape information, and acquire model shape information, a data processor configured to generate three-dimensional tooth data, a data transmission unit configured to transmit the three-dimensional tooth data, a main body accommodating the optical three-dimensional measurement unit, the data processor, and the data transmission unit, and at least two intraoral scanning tips configured to be alternately detachable to the main body and provide light paths, wherein the at least two intraoral scanning tips includes a model scanning tip for scanning a dental model.

A dental method and associated apparatus is disclosed in which a navigation body, comprising a plurality of navigation elements, is scanned using a scanner. Relative locations of the navigation elements are determined and, based on the relative locations, a scanner coordinate system is determined. A dental model is also scanned using the scanner to obtain three-dimensional virtual image data of the dental model and the scanner coordinate system is associated with the image data. A three-dimensional virtual image of the dental model is positioned, based on the three-dimensional virtual image data, within a three-dimensional virtual scene. The virtual scene is associated with a virtual articulator coordinate system, and the positioning of the virtual image within the virtual scene comprises positioning and orienting the virtual image relative to the virtual articulator coordinate system based on a transformation of the virtual image data from the scanner coordinate system to the virtual articulator coordinate system.
