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 apparatuses (including software) for optimizing dental treatment plans, including for optimizing the treatment plans using dental aligners. These methods and apparatuses may optimize a treatment plan by estimating a difference between a target set of tooth position and a predicted set of tooth positions using the treatment plan using a prediction network trained to use multiple translational and rotational directions for individual teeth as well as reaction forces on the individual teeth based on adjacent teeth.

Abstract: Apparatuses and methods for customized retainers to prevent relapse. In particular, described herein are customized retainers, and methods and apparatuses for making customized retainers that specifically reenforce and prevent movement of one or more teeth having a higher likelihood of relapse following completion of an orthodontic treatment plan.
