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: The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment placement structure. One dental attachment placement apparatus includes a body having an attachment placement surface that is to be placed on an attachment affixing surface of a tooth and wherein the attachment placement surface includes a portion that is shaped to allow placement of an attachment at a particular position on the affixing surface of the tooth and a portion of the body having a contour that is shaped to correspond with a contour of an alignment surface of a tooth and when the contour of the body and the corresponding contour is aligned, the attachment is located at the particular position and can be secured to the affixing surface of the tooth.

Abstract: A system and method for post-processing of polymeric items having a liquid component and a predetermined heat deflection temperature is provided. The system includes a washing station to spray water at elevated temperature and pressure on the items while maintaining the temperature of the item below the heat deflection temperature. Then using a water distillation system to separate the water from the water mixed with the liquid polymer component by evaporating the water using heating coils with surface that is not conducive to adhesion of the liquid polymer component and then condense the water vapor into liquid water. The system may further include a spin station to separate the liquid polymer component by spinning the item. The system may further include one or more processing stations to rinse the item, dry the item, cure the item, remove the item from a tray to which the item may be attached and clean trays after removing the item. A conveyor system may be used to automate the post-processing of the items.

Abstract: Method and system for managing multiple impressions of a patient's jaw for an orthodontic treatment are provided. The method includes scanning at least a first impression and a second impression of the same jaw for the orthodontic treatment; determining if the first jaw impression and the second jaw impression have distortion in different areas; selecting the first jaw impression or the second jaw impression as a base impression; and replacing distorted tooth data from the base impression with data for the same tooth from a non-base impression. The method also includes scanning at least a first jaw impression for the orthodontic treatment; scanning a bite impression for the orthodontic treatment; matching the scanned first jaw impression with the scanned bite impression; comparing bite information with a tooth occlusal surface; and determining if reconstruction is to be performed on the tooth occlusal surface.
