Described herein are intraoral scanning apparatuses comprising visible light and near-infrared (near-IR) light images from a patient's dentition. These apparatuses may display a 3D model of the patient's dental arch and a plurality of images of the patient's dental arch taken from different angles and positions relative to the patient's dental arch, and may both generate and display a two-dimensional (2D) image based on a relative angle and position between the indicator relative to the 3D model of the patient's dental arch.

Diagnostic intraoral scanning apparatuses

Methods for tracking progress of a patient undergoing orthodontic treatment are provided. In some embodiments, a method includes receiving a 3D model of a dental arch. The 3D model can be generated by receiving a plurality of images of the dental arch, at least some of the images including a portion of the dental arch together with a portion of a reference element. A registration can be determined between an image and at least one other image using the portions of the reference element in the respective images to improve registration accuracy. The plurality of images can be stitched together according to the determined registrations to generate the 3D model of the dental arch. The method can further include assessing progress of the orthodontic treatment by comparing the 3D model of the dental arch to a previous 3D model representing an earlier state of the dental arch.

Methods for tracking orthodontic treatment progress

Methods and apparatuses for generating and displaying a model of a subject's teeth. Described herein are intraoral scanning methods and apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth). These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth.

Intraoral scanning apparatus

Systems and methods for prioritization of three dimensional dental elements. The systems and methods may include displaying a perspective of a 3D digital model such that a portion of a second object is behind a first object, where the first object has a higher priority than the second object. The portion of the second object behind the first object may not be viewable through the first object and a reference point on the portion of the second object may not be selectable. The priority may be changed such that the second object has a higher priority than the first object, where once the priority is changed, that the portion of the second object behind the first object may be viewable through the first object and the reference point on the second object is selectable by the user.

Prioritization of three dimensional dental elements

Various methods and systems for designing a restored smile are provided. One method includes receiving scan data of a patient's teeth, developing a digital model of the patient's teeth via a computing device, where the model represents the patient's teeth based upon the scan data, creating a dental treatment plan to restore one or more teeth from an initial condition to a successive condition, and wherein a final condition of the one or more is based on the one or more teeth having at least one planned additional restorative tooth structure provided therewith.

Smile designer

In particular embodiments, method, apparatus and system for receiving digital representations of the initial parameters of a dentition; simulating a first orthodontic treatment process on the digital representations of the initial parameters, displaying a set of output results from the simulation of the first orthodontic treatment process, simulating a second orthodontic treatment process on the output results from the simulation of the first orthodontic treatment process, and displaying a set of output results from the simulation of the second orthodontic treatment process are provided.

Method and system for dental visualization

Intraoral scanning systems configured to perform computer-implemented methods for identifying dental features. The methods may include engaging a trained machine learning network to identify one or more dental features in one or more regions of a patient's dentition. Each of the dental features may be present in at least one of multiple records. Each of the records may include multiple images of the patient's dentition and may be taken with a different imaging modality. The confidence score may be determined or adjusted using aD model of the patient's dentition. The confidence score may be determined or adjusted based on the region of the patient's dentition within each record. The methods may include displaying an indicator of each dental feature that has a confidence score that is above a threshold on theD model of the patient's dentition, and modifying the display as a user adjusts the threshold.

Diagnostic intraoral methods and apparatuses

A method may include identifying a jaw position of a misaligned jaw of a patient from the virtual image of the patient's jaw and providing a treatment plan. The treatment plan may include tooth repositioning forces and jaw repositioning forces. The method may also include virtually modeling application of jaw repositioning forces between a first repositioning jaw element and a second repositioning jaw element to obtain a virtual model of the application of the jaw repositioning forces on the virtual model of the patient's jaw, identifying one or more constraints limiting the application of the jaw repositioning forces to the misaligned jaw, and adjusting the first repositioning jaw element and the second repositioning jaw element to accommodate the one or more constraints.

Methods and devices for jaw repositioning

Methods for accommodating dental implants in treatment planning. Methods may include generating a treatment plan to treat a dentition using a series of dental appliances, where a position of a digital implant in a digital dental model is identified. At least one dental appliance of the series of dental appliances may be created, where the at least one dental appliance may be shaped to implement at least one stage of the treatment plan and include an offset portion that is shaped to provide a space between the offset portion and an actual implant to avoid impingement of the at least one dental appliance on the actual implant and allows for osseointegration of the actual implant.

Dental implant positioning in treatment planning

A series of a palatal expanders increasing width can be used to gradually expand a patient's palate. Each palatal expander may have a palatal region flanked by teeth regions. The palatal region can have a plurality of anchor-receiving features (e.g., anchor interfaces) that allow the palatal expander to be attached to temporary anchorage device anchors that have been implanted into the patient's maxilla.

Systems and methods including palatal expanders with anchor interfaces

Embodiments include receiving intraoral scan data comprising a plurality of intraoral images of a dental site generated during scanning of the dental site by an intraoral scanner, a plurality of ink markings each comprising a pattern of ink having been temporarily stamped or tattooed onto a gingival surface at the dental site prior to the scanning of the dental site, wherein at least two intraoral images of the plurality of intraoral images comprise representations of one or more ink markings of the plurality of ink markings. Embodiments further include performing registration between the plurality of intraoral images based at least in part on the one or more ink markings, generating a three-dimensional (3D) model of the dental site using the plurality of intraoral images that have undergone registration, and outputting the generated 3D model to a display.

Image registration of intraoral images using ink markings

A current digital dental model is received that includes a representation of the set of physical teeth for the patient with the current dental appliance attached to the physical teeth or oral cavity. The current digital dental model is a direct digital scan of the set of physical teeth and the current dental appliance. The physical teeth are at a position in treatment when all or a part of the current dental appliance is desired to be removed from one or more of the set of physical teeth and it is desired to use a subsequent appliance. The current digital dental model is created based a new digital dental model that includes the representation of the set of physical teeth without including the current dental appliance.
