Abstract: Methods and systems for forming dental attachment formation apparatuses. Methods may include creating a virtual dental attachment formation apparatus including a body having a surface shaped to conform to contours of a virtual model of a patient's dentition, a well in the body that is shaped to receive a dental attachment, and a light path directed through the body to the well. A physical dental attachment formation apparatus may be manufactured based on the virtual dental attachment formation apparatus. At least a portion of the body of the physical dental attachment formation apparatus may be made of a light transmissive material. The physical dental attachment formation apparatus may include an opaque portion arranged to keep light from illuminating another portion of the body other than the well.

Abstract: A dental appliance includes a first segment comprising a first plurality of tooth receiving cavities shaped to receive and to impart a first distalization force in a distal direction on a first part of a patient dentition on a first jaw. The dental appliance further includes a second segment comprising a second plurality of tooth receiving cavities shaped to receive and to impart a second distalization force in the distal direction on a second part of the patient dentition. The dental appliance further includes a connector shaped to span a plurality of anterior teeth of the patient dentition and to leave open a labial side of the plurality of anterior teeth. The connector operates to decrease transmission of one or more forces between the first segment and the second segment to limit transmission of at least one of the first distalization force or the second distalization force to the plurality of anterior teeth.

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 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.

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: An orthodontic aligner includes a first plastic segment having a first shape that fits over a first portion of a dental arch of a patient, a second plastic segment having a second shape that fits over a second portion of the dental arch of the patient, and a connector that joins the first plastic segment to the second plastic segment. The connector is configured to be disposed along a lingual side of one or more additional teeth of the patient without exerting a clinically significant force on the one or more additional teeth. The connector spans a gap between the first plastic segment and the second plastic segment, the gap corresponding to the one or more additional teeth that are not to receive the clinically significant force. The connector includes a flexible material that will perform at least one of flex, move or change shape responsive to applied forces.
