Abstract: Systems and methods for forming eruption compensation (EC) features in dental appliances for accommodating erupting teeth. An EC feature may be oversized compared to a predicted geometry of an erupting tooth, thereby allowing natural eruption of the tooth when a subject wears the dental appliance. The size, shape, location and/or orientation of the EC feature may be determined based on a virtual EC region in a virtual dental model of the subject's teeth. Dimensions of the virtual EC region may be calculated using a scaling process applied to the predicted geometry of the erupting tooth. In some cases an asymmetric scaling may be used to provide a prescribed larger lingual or buccal side of the EC region to accommodate an ectopically erupting tooth.

Abstract: 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.

Abstract: 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.

Abstract: Apparatuses and methods for assessing a dental x-ray image and predicting tooth eruption and/or exfoliation. The apparatuses may use one or more trained neural networks to assess a patient's x-rays as well as dental measurements determined from the patient's x-rays to predict approximately when a permanent tooth may erupt to replace a baby tooth. The neural networks may be trained using a data training set of x-ray images and accompanying dental measurement data.
