A system for correcting malocclusions may include a maxillary appliance having tooth receiving cavities shaped to receive teeth of a maxilla and a first elastic coupling at gingival line of the maxillary appliance. The first elastic coupling may be configured for receiving an elastic. The system may also include mandibular appliance having tooth receiving cavities shaped to receive teeth of a mandible. The system may also include a corrective appliance having a first coupling configured to be coupled to the mandibular appliance at a first location on a first side of incisors of a patient and a second coupling configured to be coupled to the mandibular appliance on a second side of the incisors, and having an arm extending from the corrective appliance towards the gingival line of the maxillary appliance and being shaped to receive the elastic.

Orthodontic appliance systems for correcting malocclusions

A method may include identifying a jaw position of a misaligned jaw of a patient from the virtual image of the patient's jaw and providing a treatment plan. The treatment plan may include tooth repositioning forces and jaw repositioning forces. The method may also include virtually modeling application of jaw repositioning forces between a first repositioning jaw element and a second repositioning jaw element to obtain a virtual model of the application of the jaw repositioning forces on the virtual model of the patient's jaw, identifying one or more constraints limiting the application of the jaw repositioning forces to the misaligned jaw, and adjusting the first repositioning jaw element and the second repositioning jaw element to accommodate the one or more constraints.

Dental aligner storage case

A support is coupled to an appliance to decrease warpage. The support may comprise a plurality of extensions coupled to the appliance to decrease warpage. The extensions can be coupled to the appliance at one or more of many locations, such as on an occlusal surface, a wall, an edge or an interior of the appliance. In some embodiments, the extensions are coupled to walls of the appliance such as a buccal wall and a lingual wall, and the extensions can be coupled to the walls of the appliance near edges of the walls, such as a gingivally facing edges of the walls that are oriented toward the gingiva when the appliance is worn.

Various structured supports for 3D printed aligners/mouth pieces

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.

Accurate method to determine center of resistance for 1D/2D/3D problems

A system for correcting class III malocclusions is disclosed. The system may include a maxilla appliance having tooth receiving cavities shaped to receive teeth of the maxilla and a first coupling for receiving an elastic. The system may also include a mandibular appliance having tooth receiving cavities shaped to receive teeth of the mandible. In some embodiments, the system includes a class III corrective appliance having a first mount shaped to engage with the mandibular arch of the patient and having a second coupling shaped to receive the elastic.

Systems and methods for correcting malocclusions of teeth

The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include identifying a misaligned jaw of a patient from a virtual image of the patient's jaw, and providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient. The virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient.

The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include identifying a misaligned jaw of a patient from a virtual image of the patient's jaw, providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient, and adjusting the position of the repositioning jaw elements on the first shell and the second shell to comply with a number of constraints. The virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient.

A series of appliances including a first appliance and a second appliance. The first appliance can be configured to receive at least one tooth of a first jaw and have a first number of bite adjustment structures extending from the lingual surface of the first appliance. The first number of bite adjustment structures can have a first shape and location specific to a first stage of the treatment plan. The second appliance can be configured to receive at least one tooth of the second jaw, have a second number of bite adjustment structures extending from the second appliance and be designed to make contact with the first number of bite adjustment structures.

Alternative bite adjustment structures

A support is coupled to an appliance to decrease warpage. The support may comprise a plurality of extensions coupled to the appliance to decrease warpage. The extensions can be coupled to the appliance at one or more of many locations, such as on an occlusal surface, a wall, an edge or an interior of the appliance. In some embodiments, the extensions are coupled to walls of the appliance such as a buccal wall and a lingual wall, and the extensions can be coupled to the walls of the appliance near edges of the walls, such as gingivally facing edges of the walls that are oriented toward the gingiva when the appliance is worn.
