Method and system for establishing an initial position of a tooth, determining a target position of the tooth in a treatment plan, calculating a movement vector associated with the tooth movement from the initial position to the target position, determining a plurality of components corresponding to the movement vector, and determining a corresponding one or more positions of a respective one or more attachment devices relative to a surface plane of the tooth such that the one or more attachment devices engages with a dental appliance are provided.

Thermoforming methods of making orthodontic appliances and orthodontic appliances preforms employ a barrier sheet positioned between an appliance sheet and a dental model during the forming step. The thermoformed orthodontic appliances are more pellucid than appliances thermoformed without the barrier sheet.

A method of treating or self-treating an orthodontic patient wearing braces or aligners to straighten their teeth using an orthodontic tool in the form of a tool set having at least three arms coupled together at one end by a fastener. The arms are rotatably movable about the fastener. One arm of the tool set has a sanding tool. Another arm has a hook. A third arm has a pick. The method includes utilizing the tool set by extending one of the arms outwardly from the other arms and inserting the leading end of the arm into the patient's mouth to perform the function.

Dental treatment can be provided by a system that overlays a treatment template on a patient's arch in mixed reality, enabling a practitioner to view a schematic of the dental treatment while administering the treatment itself. The system employs a physical guide which includes stabilizing pieces to hold the guide steady with respect to the area of the arch where treatment is being administered. When the physical guide is scanned, a virtual guide is produced, in relation to which the treatment template can be defined. When the physical guide is installed on the patient, the virtual guide is aligned with the physical guide, thus aligning the template with the physical arch. With the physical guide firmly in place, the guides provide abundant feature points for reliable alignment which can be maintained even while practitioners and patient's readjust their positioning throughout a treatment, or in situations where the oral anatomy may not be visible to a mixed reality device.
