Abstract: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These palatal expanders may be configured to have a variable surface smoothness on one side (e.g., the lingual-facing surface) compared to the opposite side (e.g., the palatal-facing surface). These palatal expanders may be configured to have a varying thickness in the palatal region. These palatal expanders may be adapted for ease in removal by the patient or caregiver (e.g., including a hinged region and/or detachment region, and/or including a thinner buccal side then occlusal side, etc.).

Abstract: Embodiments are provided for using an individualized orthodontic treatment index. One method embodiment includes receiving an initial virtual dental model from a first scan of a patient's dentition, modifying the initial virtual dental model to create a target virtual dental model according to a treatment goal, assigning a number of dental references to the target virtual dental model, receiving a treatment outcome virtual dental model from a second scan of the patient's dentition, mapping the number of dental references from the target virtual dental model to a treatment outcome virtual dental model, and calculating an individualized treatment index score for the treatment outcome virtual dental model according to one or more differences between the target virtual dental model and the treatment outcome virtual dental model based on the number of dental references.

Abstract: Dental appliances having modified gingival edge profiles for optimizing orthodontic tooth movement. In some cases, at least a portion of the gingival edge is lengthened to extend past the gumline of the patient, thereby directing forces closer to a center of resistance of one or more teeth. In some cases, at least a portion of the gingival edge is shortened with respect to the gumline of the patient, thereby directing forces farther from a center of resistance of one or more teeth. The change in the force system of the dental appliance due to the gingival edge modification can be tailored and tuned for specific tooth movements.

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 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: A system and method for determining a center of resistance of a tooth may include receiving a 3D digital representation of an initial arrangement and a final arrangement of a patient's teeth and determining a 3D treatment plan. The 3D treatment plan may include a plurality of 3D stages for rearranging the teeth from the initial arrangement toward the final arrangement. The method may also include determining, in accordance with the 3D treatment plan, an intended movement of the teeth for each of the stages and deriving, using a 3D resistance model, an applied force system for achieving the intended movement of the teeth for each of the stages. The method may also include deriving 3D geometries of oral appliances for the stages in response to the applied force system. Various other systems and methods are also disclosed.

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.
