    Abstract: Improved dental models for use in dental procedures are provided. In one aspect, a unitary dental model of an intraoral cavity of a patient having a dental implant comprises a physical surface representative of gingival tissue of the patient. The model can comprise a channel shaped and oriented to receive an abutment corresponding to a physical abutment to be connected to the dental implant, in which the channel extends to an opening in the physical surface. The channel can comprise a first portion shaped to receive and constrain a corresponding structure of the abutment to a position and orientation and a second portion shaped to receive a fastener to couple the abutment to the unitary dental model. In many embodiments, the first portion comprises a shoulder shaped to receive the corresponding structure of the abutment in order to position the abutment along the channel.

    Abstract: A method of generating a virtual 3D model of a dental arch is provided. The method includes receiving intraoral scans of a dental arch, determining a first depth of a first intraoral 3D surface in a first intraoral scan, and determining a second depth of a second intraoral 3D surface in the first intraoral scan, and wherein there is a fixed distance between the first intraoral 3D surface and the second intraoral 3D surface in the first intraoral scan. The method further includes stitching together the intraoral scans and generating a virtual 3D model of the dental arch from the intraoral scans, wherein the fixed distance between the first intraoral 3D surface and the second intraoral 3D surface is included in the virtual 3D model.

    Abstract: Improved orthodontic appliances, along with related systems and methods, are provided. In one aspect, an appliance includes a shell having a plurality of cavities shaped to receive teeth, a discontinuity formed in the shell, and an elastic member positioned to interact with the discontinuity. In another aspect, an appliance includes a plurality of discrete shell segments joined by an elastic material to form a single appliance shell. In another aspect, an appliance includes a shell having an exterior layer and an interior layer having a stiffness less than a stiffness of the exterior layer, and a discontinuity formed in the exterior layer. In another aspect, an appliance includes a shell comprising an interior surface and an exterior surface, and an elastic coating covering at least a portion of one or more of the interior surface or exterior surface of the shell.
