Abstract: Apparatuses and methods for assessing a dental x-ray image and predicting tooth eruption and/or exfoliation. The apparatuses may use one or more trained neural networks to assess a patient's x-rays as well as dental measurements determined from the patient's x-rays to predict approximately when a permanent tooth may erupt to replace a baby tooth. The neural networks may be trained using a data training set of x-ray images and accompanying dental measurement data.

Abstract: A dental attachment placement device comprises a plurality of registration elements shaped for placement on a plurality of teeth and one or more flexible arms for biasing the registration element to a tooth. A first a first flexible arm may extend from a registration element on a lingual side. The first flexible arm may have a connected end and a distal end. The distal end may be configured to extend at least part way over the tooth and apply a lingual force to bias the registration element against the tooth.

Abstract: Methods and apparatuses for generating ortho-restorative treatment plans and orthodontic aligners. The ortho-restorative treatment plan may include prescribed movements of one or more teeth to correct mal-positioned teeth while accounting for planned restorative treatments on a patient's dentition. The methods may include forming a virtual target dentition model having a target restorative feature, and one or more virtual intermediate dentition models having one or more intermediate restorative features having a different shape and/or size as the target restorative feature. The methods may be used generate a series of aligners in accordance with the ortho-restorative treatment plan.

Abstract: A dental attachment placement device comprises a plurality of articulated registration elements shaped for placement on a plurality of teeth, which can facilitate placement, accommodate tooth movement, and improve alignment of the registration elements with the teeth, so as to accurately position an attachment for placement. An orthodontic device may include a plurally of registration element. A plurality of first flexible arms may extend from each registration element on a lingual side. The first flexible arm may have a connected end and a distal end. The distal end may be configured to extend at least part way over the tooth and apply a lingual force to bias the registration element against the tooth. A plurality of attachment supports may each be located on a buccal side of the plurally of registration elements and include an attachment frame that is releasably coupled to an attachment.

Abstract: A dental attachment placement device comprises a plurality of articulated registration elements shaped for placement on a plurality of teeth, which can facilitate placement, accommodate tooth movement, and improve alignment of the registration elements with the teeth, so as to accurately position an attachment for placement. The plurality of registration elements may comprise one or more attachment supports and one or more retention supports extending from the plurality of registration elements. A dental attachment can be removably coupled to the attachment support. The plurality of registration elements and attachment supports may be located on opposing sides of one or more teeth in order to maintain placement prior to adhering the attachment to the tooth. In some embodiments, each of the plurality of registration elements comprises a tooth registration surface shaped to engage the tooth with a specific position and orientation for accurate positioning of the attachment.
