Abstract: A method of making a transfer apparatus includes providing a physical mockup having a shape that corresponds to a positive shape of a patient's dental arch and a positive shape of one or more appliance analogs including ramps extending in a generally gingival direction from the analog. A transfer tray may be formed over the physical mockup, with the transfer tray representing a negative replica of at least a portion of the mockup. One or more receptacles and related channels are accordingly formed in the ray, each receptacle approximating a least a portion of the shape of an appliance analog and each channel approximating at least a portion of the shape of a ramp. An appliance associated with an appliance analog is placed into a receptacle of the one or more receptacles, and the appliance may be bonded to a tooth surface of the patient's dental arch.

Abstract: Methods for recognizing a virtual tooth surface, defining a virtual tooth coordinate system, and simulating a collision between virtual teeth are provided. Methods include receiving input data specifying a point on the rendered surface model associated with a tooth, deriving a perimeter on the surface model of the tooth based on the input data, and analyzing the surface model along a plurality of paths outwardly extending from points on the perimeter along the three-dimensional surface to produce gingival margin data. Methods also include receiving point input data that defines a point on the virtual tooth, receiving axis input data that defines first and second axes associated with the virtual tooth, computing a substantially normal vector for a portion of the tooth surface surrounding the point, and computing a coordinate system based on the axis input and the computed vector. Methods also include receiving permissible movement input data directed to permissible movement of a first virtual tooth, simulating, in three dimensional space, bringing the first virtual tooth into contact with a second virtual tooth while constraining movement of the first virtual tooth based on the permissible movement input data, and displaying data resulting from the simulation.

Abstract: Methods for generating intermediate stages for orthodontic aligners using machine learning or deep learning techniques. The method receives a malocclusion of teeth and a planned setup position of the teeth. The malocclusion can be represented by translations and rotations, or by digital 3D models. The method generates intermediate stages for aligners, between the malocclusion and the planned setup position, using one or more deep learning methods. The intermediate stages can be used to generate setups that are output in a format, such as digital 3D models, suitable for use in manufacturing the corresponding aligners.
