Abstract: A dental articulator includes a first arm hingedly joined to a second arm about a pivot axis, where each one of the first arm and the second arm are configured to mount a dental model comprising at least one measurement element, and an inspection tool capable of checking the at least one measurable element against allowable tolerances. Each arm includes a mounting bracket having a distal portion adapted to mount the respective dental model and having a proximal portion. Each arm further has a base member having a distal portion adapted to hingedly join the first arm and the second arm about the pivot axis. The inspection tool comprises a first measurement device and a second measurement device. The first measurement device is coupled to the first arm or second arm and the second measurement device is coupled to the first arm or second arm.

Abstract: Intraoral systems and methods including aligners having soft tissue sensors. The soft tissue sensors may detect protein biomarkers to determine effectiveness of the aligners for causing tooth movement according to a treatment plan. One or more microneedles may be configured to pass the protein biomarker to the soft tissue sensor. A processor may be configured to compare a detected level of the protein biomarker to an expected lever of the protein biomarker, and determine whether an aligner should be replaced. A bias may be configured to apply continuous force to hold the microneedle(s) against a patient's soft tissue. A controller may be configured to apply a biasing force to move the microneedles(s) from a retracted position to an extended position to penetrate the patient's soft tissue.

Abstract: The disclosed computer-implemented method for selecting locations of mandibular relocation features (MRFs) on oral appliances may include determining candidate locations for placing an MRF on a first oral appliance for a first stage of mandibular relocation (MR) treatment and determining candidate locations for placing an MRF on a second oral appliance for a second stage. The method may include selecting from the candidate locations for the first stage and the second stage based on decreasing a distance between the selected pair of candidate locations. The method may further include processing multiple MRFs in parallel. The method may also include increasing a number of initial candidate locations. Locations for intermediate stages may be selected based on interpolating between the first and second stages or based on decreasing a distance between the selected pair if the interpolation fails. The intermediate stages may be processed using a binary search or a linear search.

Abstract: Remote progress tracking of orthodontic treatment may include receiving a 3D digital model of a patient's dentition including the patient's teeth. A 3D digital model of an impression of occlusal surfaces of the patient's teeth may be generated. The teeth of the 3D digital model of the patient's dentition may be registered to the position and orientation of the patient's teeth in the 3D digital model of the impression of the occlusal surfaces of the patient's teeth. An updated 3D digital model of the patient's teeth may be generated based on the registration.

Abstract: An apparatus for determining surface topography of a patient's teeth comprises a probe sized to be at least partially inserted into an intraoral cavity of the patient, a light source to output light; and a light focusing assembly. The light focusing assembly comprises a first lens, a second lens and a focus changing assembly comprising one or more additional lenses that shares an optical axis with the first lens and the second lens and being configured to focus the light to a plurality of external focal planes to illuminate the patient's teeth, wherein the focus changing assembly has a movement gain factor, and wherein as a result of the movement gain factor a change in separation between lenses of the focus changing assembly by a first distance results in a change in a focus setting by a second distance that is 2-10 times greater than the first distance. The apparatus further comprises a detector configured to measure one or more characteristics of incident light returning from the illuminated patient's teeth and a processor coupled to the detector and configured to generate data representative of a topography of the patient's teeth based on the one or more measured characteristics of the incident light returning from the illuminated patient's teeth.

Abstract: A system includes a memory and a processing device operatively coupled to the memory. The processing device receives an image of a smile of an individual comprising initial contours of teeth of the individual, receives or generates image data comprising target contours of the teeth of an individual, and generates a new image based on the received image data and one or more parametric functions associated with tooth color determined from the image of the smile, wherein a shape of the teeth in the new image is based on the received image data and a color of the teeth in the new image is based on applying the one or more parametric functions to at least a portion of the image data.

Abstract: A method of generating a 3D model includes: determining a 3D surface comprising a preparation tooth using a first plurality of intraoral scans generated by an intraoral scanner at a first time; receiving one or more additional intraoral scans of the preparation tooth that were generated by the intraoral scanner at a second time; determining a change to one or more portions of the preparation tooth between the three-dimensional surface and the one or more additional intraoral scans; determining, based at least in part on the change to the preparation tooth, whether to use a) the 3D surface, b) data from the one or more additional intraoral scans or c) a combination of the 3D surface and the data from the one or more additional intraoral scans to depict one or more portions of the preparation tooth; and generating the 3D model comprising the preparation tooth.

Abstract: A method for preparing a tooth crown may include generating a 3D model of an external surface of a patient's tooth and generating a 3D model of an external surface of a first crown based on the 3D model of the external surface of the patient's tooth. The method may also include preparing the patient's tooth to receive the first crown while generating the 3D model of the external surface. A 3D model of the prepared tooth my be generated. A 3D model of an internal surface of the first crown may also be generated. The 3D model of the external surface and the 3D model of the internal surface may form a 3D model of the first crown.

Abstract: Systems and methods of simulating dental treatments are disclosed. A method may include capturing a first 2D image of a patient's face, including the patient's teeth, building a parametric 3D model of the patient's teeth and gingiva based on the first 2D image, developing a simulated outcome of a dental treatment of the patient's teeth by rendering the parametric 3D model with the patient's teeth in one or more positions and/or orientations corresponding to the treatment goals of the dental treatment plan, and rendering a second 2D image of the patient's face with gingiva and teeth according to a simulated outcome of the dental treatment plan. As noted herein, the dental treatment plan may include orthodontic and/or restorative elements. The simulated outcome may correspond to estimated outcomes and/or intended outcomes of the dental treatment plan.
