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: A series of appliances including a first shell and a second shell can be designed to incrementally implement a treatment plan. The first and second shells can have cavities designed to receive teeth of a jaw. A first number of bite adjustment structures can be formed of a same material as the first shell, extending therefrom and designed to interface with teeth of a second jaw. The first number of bite adjustment structures can have a first shape and location specific to a first stage of the treatment plan. A second number of bite adjustment structures can be formed of a same material as the second shell, extending therefrom and designed to interface with teeth of the second jaw. The second number of bite adjustment structures can have a second shape and location, different than the first shape and location, specific to a second stage of the treatment plan.

Abstract: The example systems, methods, and/or computer-readable media described herein help with design of highly accurate models of un-erupted or partially erupted teeth and help fabricate of aligners for un-erupted or partially erupted teeth. Automated agents that use machine learning models to parametrically represent three-dimensional (3d) virtual representations of teeth as 3D descriptors in a 3D descriptor space are provided herein. In some implementations, the automated agents described herein provide instructions to fabricate aligners for at least partially un-erupted teeth using representative 3D descriptor(s) of a tooth type.

Abstract: A method includes to receive, via a computing device, data representing a plurality of teeth, identify data indicating which of the plurality of teeth are unerupted or erupting, predict at least one characteristic of a tooth of the unerupted or erupting teeth after they have fully erupted using one or more tooth eruption prediction factors, generate new data representing the unerupted or erupting teeth in multiple states of eruption based upon the predicted at least one characteristic of the fully erupted teeth, and generate a series of incremental tooth arrangements with the new data to define a proposed orthodontic treatment based on the new data representing the unerupted or erupting teeth in multiple states of eruption.

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.

Abstract: Methods and systems are provided for generating a treatment plan for arch expansion where a polymeric shell appliance is utilized to generate one or more activation forces that facilitate tooth movement. The polymeric shell appliances may comprise one or more tooth receiving cavities, in which each of the plurality of tooth receiving cavities is shaped and arranged to provide a counter moment of each of the plurality of teeth.
