    Abstract: The present disclosure provides computing device implemented methods, computing device readable media, and systems for adjustment of tooth position in a virtual dental model. Virtual dental modeling can include detecting space and/or collision between posterior teeth of an upper jaw and posterior teeth of a lower jaw in a virtual dental model that has been set in a preliminary target position. An energy function can be defined including the space and/or collision, tooth root movement, and align points. Weights can be assigned for each variable in the energy function. A position of the posterior teeth of the upper jaw and the posterior teeth of the lower jaw can be adjusted in six degrees of freedom to minimize the energy function. The detection, definition, assignment, and adjustment can be repeated until the energy function converges. The weights can be adjusted to reduce the space and/or collision.

    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: A method may include generating a model of an orthodontic appliance having a shell having teeth receiving cavities shaped to receive and reposition the patient's teeth. At least one of the cavities may be shaped to apply a resilient repositioning force to move at least one of the patient's teeth from a current arrangement toward a target arrangement. The method may include forming a ridge on the at least one of the cavities having a width and a length greater than the width. The ridge may be configured to apply at least a portion of the resilient repositioning force to the at least one of the patient's teeth. The method may also include modeling the orthodontic appliance with the ridge on the patient's teeth and modifying a portion of the shell to compensate for modeled contact of the portion of the shell with the at least one patient's tooth.

    Abstract: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems include the generation of an overcorrection in the tooth-receiving cavities of an appliance worn in the dentition. The overcorrection may provide an improved and more accurately applied force or moment applied to a tooth. The overcorrected force or moment can move a tooth closer to a desired position than if not overcorrected as sufficient force can still applied to the tooth as it gets closer to the desired position. The overcorrected force or moment may also better target the root of the tooth where the biological response to tooth movement occurs. The overcorrection may be calculated in various ways as described herein.

    Abstract: The present disclosure includes computing device related, systems, and methods for identifying force placed on a tooth are described herein. One method includes receiving initial orthodontic data (IOD) including teeth data; creating a virtual set of teeth from the IOD; receiving dental appliance information including at least one of dental appliance material properties and characteristics; virtually placing a dental appliance, formed from the dental appliance information, onto the virtual set of teeth; and determining one or more forces applied to the teeth based on information from the IOD and dental appliance information.
