Abstract: Methods and systems for digitally designing a plurality of aligners are provided. In some embodiments, a method includes receiving an intraoral scan of the patient's teeth, and generating 3D dental model of the patient's teeth using the intraoral scan. The method can include identifying a movement path to move the patient's teeth from an initial arrangement toward a target arrangement through a plurality of intermediate arrangements in accordance with a treatment plan. The method can also include identifying one or more appliance features of at least one aligner, the one or more appliance features including one or more feature regions having one or more feature thicknesses. The method can further include instructing an additive manufacturing machine to directly fabricate the at least one aligner in a layer-by-layer fashion.

Abstract: Systems, methods, and devices for improved orthodontic treatment of a patient's teeth are provided herein. In some aspects, a method for fabricating an orthodontic appliance for treating a patient's teeth is disclosed. The method may comprise determining a movement path to move a tooth from an initial arrangement towards a target arrangement; determining a force system to move the tooth along the movement path; determining a variable gable bend to produce the force system; determining a geometry for a tooth receiving cavity of the appliance based on the variable gable bend; and generating instructions for fabricating the appliance having a tooth receiving cavity formed according to the geometry for the tooth receiving cavity.

Abstract: A mold includes a main body and a separable feature. One or more first weakened regions join the separable feature to the main body. The one or more first weakened regions are breakable to enable the main body to be removed from a shell independently of the separable feature after the shell is formed over the mold. The main body includes a first section and a second section that are at least partially separable at one or more second weakened regions to enable the first section to be removed from the shell independently of the second section after the shell is formed over the mold.

Abstract: 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. The first shell can be designed to interface with a first surface of a plurality of surfaces of an attachment structure to provide a first engagement force specific to a first stage of the treatment plan. The second shell can be designed to interface with a second surface of the plurality of surfaces of the attachment structure attached to the at least one tooth of the first jaw to provide a second engagement force specific to a second stage of the treatment plan.

Abstract: A method includes forming a plastic orthodontic aligner having a plurality of cavities shaped to receive at least portions of a plurality of teeth of a patient. A first segment of the plastic orthodontic aligner corresponds to a first subset of the plurality of cavities for moving a first subset of the plurality of teeth of the patient. A second segment of the plastic orthodontic aligner corresponds to a second subset of the plurality of cavities. The method further includes removing a first portion of the plastic orthodontic aligner between the first and second segments of the plastic orthodontic aligner to form a connector to minimize force transmission between the first and second segments. The connector is configured to be disposed along one or more additional teeth to span a gap between the first and second segments without exerting a clinically significant force on the one or more additional teeth.
