20080233529 | Active attachments for interacting with a polymeric shell dental appliance - An active dental attachment. Specifically, an attachment device for interacting with a polymeric shell dental appliance is described. The attachment device includes an anchoring attachment body. A bonding surface is coupled to the anchoring attachment body, wherein the bonding surface is configured for anchoring the anchoring attachment body to a dental feature of a patient's dentition. A force-applying active mechanism is coupled to the anchoring attachment body. A polymeric shell dental appliance contact region is coupled to the force-applying active mechanism. The polymeric shell dental appliance contact region is configured to contact the force-applying active mechanism and apply a force generated by the force-applying active mechanism between the dental feature and the polymeric shell dental appliance when the polymeric shell dental appliance engages the force-applying active mechanism. | 09-25-2008 |
20100151404 | TOOTH MOVEMENT MEASUREMENT BY AUTOMATIC IMPRESSION MATCHING - The present invention relates to systems and methods for detecting deviations from an orthodontic treatment plan. One method includes receiving a tracking model, performing a matching step between individual teeth in a plan model and the tracking model, comparing the tracking model with the plan model, and detecting one or more positional differences. | 06-17-2010 |
20110104630 | GENERATING A DYNAMIC THREE-DIMENSIONAL OCCLUSOGRAM - Methods and systems for generating a three-dimensional occlusogram are disclosed. One method includes determining a virtual three dimensional (3D) mesh model object of at least one tooth of a patient and displaying the determined virtual 3D mesh model object of at least one tooth of a patient wherein the 3D mesh model object includes a plurality of data sets associated with a set of occlusal information for the at least one tooth of the patient. | 05-05-2011 |
20110137626 | SYSTEM AND METHOD FOR AUTOMATED CONSTRUCTION OF ORTHODONTIC REFERENCE OBJECTS - System and method for automatic construction of orthodontic reference objects, such as the occlusal plane, arch form, and the local occlusal plane for a patient's teeth are disclosed. In accordance with an exemplary embodiment, a computer-implemented system and method for automatic construction of orthodontic reference objects comprises receiving three dimensional data for the teeth, setting an initial direction for a normal of the occlusal plane, determining tips for selected teeth, calculating a plane that matches the determined tip, and determining a new normal for the calculated plane. | 06-09-2011 |
20110270588 | INDIVIDUALIZED ORTHODONTIC TREATMENT INDEX - 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. | 11-03-2011 |
20120166163 | SYSTEM AND METHOD FOR AUTOMATIC CONSTRUCTION OF ORTHODONTIC REFERENCE OBJECTS - System and method for automatic construction of orthodontic reference objects, such as the occlusal plane, arch form, and the local occlusal plane for a patient's teeth are disclosed.

20130204599 | VIRTUALLY TESTING FORCE PLACED ON A TOOTH - Embodiments of the present disclosure include computing device related, system, and method embodiments for virtually testing force placed on a tooth are described herein. One method embodiment includes receiving initial orthodontic data (IOD) of teeth, and receiving a desired position of a tooth contained in the IOD. The method embodiment can also include computing a desired force and torque to be applied to the tooth to reach the desired position, wherein the force and torque are applied using a dental attachment. The method embodiment can include virtually testing and adjusting the attachment iteratively to reach the desired force and torque, and displaying the force and torque applied to the tooth via a user interface. | 08-08-2013 |
20130317800 | ADJUSTMENT OF TOOTH POSITION IN A VIRTUAL DENTAL MODEL - 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. | 11-28-2013 |
