摘要： 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.

摘要： Methods and apparatuses for 3D imaging (including 3D optical coherence tomography imaging) to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and/or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact. These measurements may be used design, modify or replace an aligner and/or to verify aligner fit. 3D models of the whole aligner and teeth may be generated.

摘要： 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 of the invention include tooth attachments having improved or optimized parameters selected or modified for more optimal and/or effective application of forces for a desired/selected orthodontic movement. Attachments of the present invention can be customized to a particular patient (e.g., patient-customized), a particular movement, and/or a sub-group or sub-set of patients, and configured to engage an orthodontic tooth positioning appliance worn by a patient, where engagement between the attachment and orthodontic appliance results in application of a repositioning force or series/system of forces to the tooth having the attachment and will generally elicit a tooth movement.

摘要： A method for digital treatment planning may include defining a set of contact points on a tooth of a patient's dentition and a plurality of connections between pairs of the plurality of contact points. The plurality of connections may include Hookian stiffness parameters of a dental appliance between the plurality of contact points. The method may also include generating a relaxed model of a dental appliance using the plurality of contact points and the plurality of connections. The method may also include generating a deformed model of the dental appliance using the plurality of contact points and plurality of connections. The method may also include transforming the relaxed model to the deformed model to direct the patient dentition towards a target tooth arrangement.

摘要： Systems and methods for designing additively manufactured objects are provided. In some embodiments, a method includes receiving a treatment plan for a patient's teeth, and determining a set of appliance parameters for a dental appliance configured to implement the treatment plan. The method can also include determining a set of manufacturing parameters for a fabrication system to be used to additively manufacture the dental appliance. The method can further include generating a 3D digital representation of an appliance geometry for the dental appliance. The appliance geometry can be configured to mitigate loss of fidelity at a target region of the dental appliance due to at least one manufacturing parameter of the fabrication system.

摘要： A series of appliances including a first shell and a second shell can be designed to incrementally implement a treatment plan. The first and second shells can have cavities designed to receive teeth of a jaw. A first number of bite adjustment structures can be formed of a same material as the first shell and extend from the first cavities and be designed to interface with teeth of a second jaw. The first number of bite adjustment structures can have a first shape and location. A second number of bite adjustment structures can be formed of a same material as the second shell and extend from the second cavities and be designed to interface with teeth of the second jaw. The second number of bite adjustment structures can have a second shape and location, different than the first shape and location.
