    Abstract: In embodiments set forth herein, an intraoral scanning system includes a first intraoral scanner, a second intraoral scanner, and a computing device wirelessly connected to both the first intraoral scanner and the second intraoral scanner. The computing device receives first intraoral scan data from the first intraoral scanner and generates a first three-dimensional (3D) surface of at least a portion of a first patient's dental arch based on the first intraoral scan data. The computing device further receives second intraoral scan data from the second intraoral scanner and generates a second 3D surface of at least a portion of a second patient's dental arch based on the second intraoral scan data.

    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: Multiple techniques for detecting defects in customized dental appliances are disclosed. In one technique, processing logic obtains one or more images of a customized dental appliance, obtains a digital model associated with the customized dental appliance, and identifies an area of the one or more images that comprises a representation of the customized dental appliance. Processing logic then registers the one or more images to the digital model, compares the area of the one or more images of the customized dental appliance with the digital model of the customized dental appliance, determines a difference between the area of the one or more images that comprises the representation of the customized dental appliance and the digital model of the customized dental appliance at a region, and determines whether the difference satisfies a defect criterion.

    Abstract: A set of primer appliances and a set of treatment appliances to be worn by a subject are provided. The primer appliances are first worn to prepare the local environment of the teeth for further repositioning of the teeth by the treatment appliances. The primer appliances may apply compression to the periodontal ligament, in a direction favorable for achieving the desired final position of a tooth. The compression may generate a biological response in the local environment of the teeth. The primer appliances may cause minimal or no repositioning of the teeth. The treatment appliances are worn to reposition the teeth from an initial position to an end positon of a treatment stage. The primer appliances can improve the efficiency and accuracy of tooth movement by the treatment appliances.

    Abstract: Multiple techniques for detecting defects in customized dental appliances are disclosed. In one technique, processing logic obtains one or more images of a customized dental appliance, obtains a digital model associated with the customized dental appliance, and performs segmentation on the one or more images to identify an area of the one or more images that comprises a representation of the customized dental appliance. Processing logic then registers the one or more images to the digital model, compares the area of the one or more images of the customized dental appliance with the digital model of the customized dental appliance, determines a difference between the area of the one or more images that comprises the representation of the customized dental appliance and the digital model of the customized dental appliance at a region, and determines whether the difference satisfies a defect criterion.
