Abstract: A processing device receives an intraoral image of a first intraoral site and determines an identity of the first intraoral site. The processing device then locks the intraoral image and selects a portion of the intraoral image depicting a portion of the first intraoral site based at least in part on the identity of the first intraoral site. 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 locked 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: An intraoral scanner generates 2D images of a dental site and 3D intraoral scans of the dental site. The computing device receives the 2D images of the dental site and the 3D intraoral scans of the dental site from the intraoral scanner, generates a 3D model of the dental site based on the 3D intraoral scans of the dental site, and processes at least one of a) one or more of the 2D images of the dental site, b) one or more of the 3D intraoral scans of the dental site, or c) data from the 3D model of the dental site to identify one or more intraoral areas of interest (AOIs) at the dental site. The computing device determines a dental condition associated with the one or more intraoral AOIs, and determines a manner for scanning the one or more intraoral AOIs.

Abstract: A method for distinguishing between types of intraoral areas of interest (AOIs) includes receiving or generating a first 3D model comprising teeth; receiving or generating a second 3D model comprising the teeth; comparing the first 3D model to the second 3D model; determining a difference between the first 3D model and the second 3D model at a dental site comprising a tooth; determining an intraoral AOI that is associated with the difference; determining whether the difference comprises a first type of change indicative of a first type of intraoral AOI or a second type of change indicative of a second type of intraoral AOI; and responsive to determining that the difference comprises the first type of change, determining that the intraoral AOI is the first type of intraoral AOI and generating an indicator of the first type of intraoral AOI for the tooth.

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: A method includes receiving intraoral scan data of an intraoral cavity of a patient; processing the intraoral scan data to determine, for each dental condition of a plurality of dental conditions, whether the dental condition is detected for the patient and a severity of the dental condition; and presenting indications of the plurality of dental conditions together in a graphical user interface (GUI), wherein the indications show, for each dental condition of the plurality of dental conditions, whether the dental condition was detected for the patient and the severity of the dental condition.

Abstract: A system and method are provided for manufacturing a physical model of a dental structure that includes a dental implant. In at least one example, the physical model is configured to allow a dental analog can be inserted into the physical model in a general coronal direction. A virtual model of the dental structure is provided including a virtual implant spatial disposition with respect to the virtual model corresponding to a physical implant spatial disposition of the dental implant with respect to the physical dental structure. A virtual analog installation structure is defined in the virtual model. Using the virtual model, a physical model corresponding to the virtual model is manufactured, the physical model being provided with a physical analog installation structure corresponding to the virtual analog installation structure. The physical analog installation structure is configured for enabling a dental analog, corresponding to the dental implant, to be inserted in a general coronal direction with respect to the physical model to an installed position in the physical model. In the installed position, the dental analog has an analog spatial disposition with respect to the physical model corresponding to the physical implant spatial disposition of the dental implant with respect to the physical dental structure. A composite physical model, and methods for manufacturing the same, are also provided.

Abstract: Methods and apparatuses for 3D imaging to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and/or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact. These measurements may be used design, modify or replace an aligner and/or to verify aligner fit. 3D models of the whole aligner and teeth may be generated.
