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.

The present disclosure provides systems that utilize a cheek retractor and/or a mobile device holder. The cheek retractor includes a first and a second lip holder to hold a cheek away from a mouth of a user to expose teeth of the user. A mobile device holder can receive a mobile device to capture images of the patient's teeth. These systems may be useful for case assessment and/or dental treatments.

A dental model and related systems and methods, including a first component representing a portion of a patient's jaw and a second component that is demountably attachable to the first component, and a second component representing a dental structure of interest, such as the remaining portion of a tooth or a dental implant.

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.

Disclosed are example embodiments of methods and systems for identifying and quantifying manufacturing defects of a manufactured dental prosthesis. Certain embodiments of the system for performing quality control on manufactured dental prostheses includes: a quality control module configured to determine whether the dental prosthesis is a good or a defective product based at least on a differences model generated by comparing a design model and a scanned model of the manufactured dental prosthesis.

A scanning object carrier (1), which is provided for installation on a scanner rocker (2) of a scanning device (3) for scanning at least one, in particular dental, object (20), wherein the scanning object carrier (1) includes a base body (4) and at least one fastening device (5) for fastening the base body (4) to the scanner rocker (2) and at least one object fixing device (6) for fixing the object (20) to the scanning object carrier (1), wherein the object fixing device (6) is mounted in a pivotable manner on the base body (4) relative to the base body (4), and wherein the object fixing device (6) is mounted in a pivotable manner on the base body (4) between two end positions (7, 8) by freely following gravity.

Example dental scanning methods for analyzing jaws of a patient involve taking multiple scans of the jaws, and/or models thereof, and then shifting the image of one scan to match that of another. In some examples, fiducial markers are attached to the patient's jaws beforehand to accurately identify and track the relative position of the jaws. The methods provide a way for creating a precise image of an upper jaw and a lower jaw in their proper bite registration, even though the resulting image may show an insufficient number of teeth to readily do so. The final, properly shifted image serves as a virtual 3D jaw model that can be manipulated and analyzed to aid in various orthodontic and other dental treatments.

Example fiducial markers include features that make them particularly useful in dental scanning methods for analyzing jaws of a patient, wherein the dental scanning methods involve taking multiple scans of the jaws, and/or models thereof, and then shifting the image of one scan to match that of another. Prior to scanning, the fiducial markers are attached to the patient's jaws to accurately identify and track the relative position of the jaws.

A scanning object carrier (1), which is provided for installation on a scanner rocker (2) of a scanning device (3) for scanning at least one, in particular dental, object (20), wherein the scanning object carrier (1) includes a base body (4) and at least one fastening device (5) for fastening the base body (4) to the scanner rocker (2) and at least one object fixing device (6) for fixing the object (20) to the scanning object carrier (1), wherein the object fixing device (6) is mounted in a pivotable manner on the base body (4) relative to the base body (4), and wherein the object fixing device (6) is mounted in a pivotable manner on the base body (4) between two end positions (7, 8) by freely following gravity.

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.
