  • Patent number: 11744530
    Abstract: Example radiographic dental jigs include a generally vertical post traversed by a generally horizontal beam to create a cross that can be used for marking a dental patient's midline (vertical line centered between the eyes), incisal edge plane, and forward lip position. The jig is radiographically scanned along with multiple fiducial markers on the patient's jaw to generate a first scan result. In some examples, physical models of the patient's jaws are also scanned to generate upper and lower jaw images. The upper and lower jaw images are shifted to coincide with the first scan result. Portions of the first scan result, including an image of the dental jig, are superimposed onto the properly shifted upper and lower jaw images to create a composite image. The composite image shows the dental jig in proper relation to the patient's upper and lower jaws, thereby rendering a conventional stick bite virtually obsolete.

  • Patent number: 11607295
    Abstract: A method of providing an accurate three-dimensional scan of a dental arch area is disclosed. The arch area has two segments and a connecting area between the two segments. The connecting area has homogeneous features. A connecting-geometry tool with at least one definable feature is affixed to the arch area. The definable feature overlays at least part of the connecting area. The arch area is scanned to produce a scanned dataset of the arch area. The definable feature of the connecting-geometry tool on the connection area is determined based on the scanned dataset. The dimensions of the arch area are determined based on the data relating to the definable features from the scanned dataset.

  • Patent number: 11571276
    Abstract: The present invention relates to systems and methods of developing and tracking delivery and patient progression through an orthodontic treatment plan. One method includes identifying deviations from an orthodontic treatment plan, including receiving a digital representation of an actual arrangement of a patient's teeth after an orthodontic treatment plan has begun for the patient and prior to completion of the orthodontic treatment plan. The method further includes comparing the actual arrangement to a pre-determined planned arrangement to determine if the actual arrangement substantially deviates from the planned arrangement, the comparing comprising matching teeth from a previously segmented model to a surface of an unsegmented representation of the actual arrangement; and calculating one or more positional differences between the actual and planned arrangements of at least some of the corresponding teeth.
