Provided herein are exemplary orthodontic elastic attachments that are customized to fit within the cutout windows of dental aligners, thus improving adhesion and minimizing inadvertent detachment from the tooth surface. The unique base pads are designed to have a shape that complements the present shape of the cutout windows like a puzzle piece. To improve adhesion to the tooth surface, the base pad may have its surface area maximized within the cutout windows. Also for improved adhesion, the base pad may be contoured to the dental anatomy of the tooth at the gumline for an intimate fit. Further exemplary embodiments may include the base pad having beveled edges to permit the aligner to slide over the base pad if it is adhered slightly off-center.

The present disclosure provides removable airway appliance for guiding and developing the lower and upper jaws forward. The present invention prevents crowding of the teeths and makes room for all the teeth, making room for all permanent teeth without crowding, creates space for all the permanent teeth. The present invention may grow the upper jaw forward and unrestrict the lower jaw that is often trapped back behind the upper jaw. The present invention guides and develops the lower and upper jaws forward, and widen the upper jaw, making room for the tongue in the mouth to maximize the airway space. In removable airway appliance, on the horizontal axis the screws can be positioned flat at a small angle or at a steeper angle to help direct the direction of growth and development of the upper and lower jawbones.

Systems for fabricating dental appliances are provided. In some embodiments, a system comprising one or more processors, and a memory operably coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the system to determine an appliance geometry for a dental appliance including a shell configured to move the patient's teeth from an initial arrangement toward a target arrangement. The appliance geometry can include a first power arm having a first connection point for connecting to the shell, a second power arm having a second connection point for connecting to the shell or to a tooth, an elongate connecting structure coupled to the first and second power arms, and an elongate counter-force connector coupled to the first power arm and extending toward the second power arm.

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.
