    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: A dual aligner assembly including a plurality of aligners, including a first aligner and a second aligner. The first aligner has a first shape corresponding to a set of target tooth positions and applies an orthodontic force against a set of target teeth. The first orthodontic force generates movement of the set of target teeth to the set of target tooth positions. The second aligner has a second shape corresponding to a combination of current tooth positions of the set of target teeth, the set of target tooth positions, and a thickness of the first aligner. The second aligner partially encloses the first aligner and provides an anchor for at least a portion of the first aligner. Via the anchor, a combination of the first aligner and the second aligner provides an orthodontic force that prevents the set of target teeth from moving to unwanted tooth positions during orthodontic treatment.

    Abstract translation: 包括多个对准器的双对准器组件，包括第一对准器和第二对准器。 第一对准器具有对应于一组目标牙齿位置的第一形状，并将正畸力应用于一组目标牙齿。 第一种矫正力产生一组目标牙齿到目标牙齿位置集合的运动。 第二对准器具有对应于组的目标齿的当前齿位置，目标齿位置集合和第一对准器的厚度的组合的第二形状。 第二对准器部分地包围第一对准器并为第一对准器的至少一部分提供锚固件。 通过锚固件，第一对准器和第二对准器的组合提供正畸力，其在正畸治疗期间防止该组目标牙齿移动到不需要的牙齿位置。

    Abstract: The present disclosure provides methods, devices, systems, and computer-implemented methods for forming and placing attachments for use with dental appliances, and more particularly to the design, manufacture, and use of three-dimensionally printed attachment templates for use with orthodontic devices. Dental attachment templates include a cavity with one or more openings for injecting and bonding attachment material directly on a patient's tooth, which allow accurate placement of the attachments while providing the dental practitioner flexibility during the attachment forming process. Digital dental attachment template model techniques can be used to accurately place the cavity and opening.

    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.
