Abstract: A processing device receives an intraoral image of a first intraoral site. The processing device selects a portion of the intraoral image that depicts a portion of the first intraoral site. The processing device locks at least the portion of the intraoral image. The processing device may then generate a model comprising the first intraoral site based at least in part on the locked intraoral image, wherein the portion of the intraoral image is used for a first region of the model, and wherein data from one or more additional intraoral images that also depict the portion of the first intraoral site is not used for the first region of the model.

Abstract: A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth. The appliance includes a hard polymer layer having a hard polymer layer elastic modulus disposed between a first soft polymer layer having a first soft polymer layer elastic modulus and a second soft polymer layer having a second soft polymer layer elastic modulus. The hard polymer layer elastic modulus is greater than each of the first soft polymer layer elastic modulus and the second soft polymer layer elastic modulus. At least one of the first soft polymer layer and the second soft polymer layer has a flexural modulus of greater than about 35,000 psi.

Abstract: The present invention relates to systems and methods of developing and tracking delivery and patient progression through an orthodontic treatment plan. One method includes identifying deviations from an orthodontic treatment plan, including receiving a digital representation of an actual arrangement of a patient's teeth after an orthodontic treatment plan has begun for the patient and prior to completion of the orthodontic treatment plan. The method further includes comparing the actual arrangement to a pre-determined planned arrangement to determine if the actual arrangement substantially deviates from the planned arrangement, the comparing comprising matching teeth from a previously segmented model to a surface of an unsegmented representation of the actual arrangement; and calculating one or more positional differences between the actual and planned arrangements of at least some of the corresponding teeth.

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: Provided herein are orthodontic devices and methods for patients whose orthodontic devices are causing a lisp. The device can comprise an aligner configured to fit over a patient's dental arch and comprising an occlusal surface section positioned over an occlusal surface of the patient's teeth. The aligner can comprise a barrier portion extending laterally and adjacent to a region of the dental arch, the barrier portion allowing the patient's tongue to form a seal against the barrier portion when the patient is speaking while wearing the device.

Abstract: A breakable or deflectable mold includes a first section, a second section, and a weakened region that joins the first section to the second section. The weakened region is breakable or deflectable to enable the first section to be removed independently of the second section after a shell is formed over the breakable mold.

Abstract: An apparatus is described for measuring surface topography of a three-dimensional structure. In many embodiments, the apparatus is configured to focus each of a plurality of light beams to a respective fixed focal position relative to the apparatus. The apparatus measures a characteristic of each of a plurality of returned light beams that are generated by illuminating the three-dimensional structure with the light beams. The characteristic is measured for a plurality of different positions and/or orientations between the apparatus and the three-dimensional structure. Surface topography of the three-dimensional structure is determined based at least in part on the measured characteristic of the returned light beams for the plurality of different positions and/or orientations between the apparatus and the three-dimensional structure.
