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: According to the invention, a method and system are provided for scanning, and for facilitating scanning of, an intraoral cavity. The target parts of the intraoral cavity that it is desired to have scanned are identified, and the spatial s relationships between a scanning device and the target parts of the intraoral cavity suitable for enabling said target parts to be scanned by said scanning device, are also identified or otherwise determined. These relationships are then displayed, and the displayed relationships are used as a guide for scanning the intraoral cavity.

Abstract: A method for manufacturing an orthodontic aligner includes printing a mold associated with a dental arch of a patient based on a digital model of the mold, forming the orthodontic aligner over the mold, and trimming the orthodontic aligner. The method further includes assessing a quality of the orthodontic aligner by receiving a digital representation of the orthodontic aligner, the digital representation having been generated based on imaging of the orthodontic aligner, analyzing the digital representation of the orthodontic aligner to identify a quality-related property of the orthodontic aligner, determining, based on the quality-related property, that the orthodontic aligner comprises a manufacturing flaw, and classifying the orthodontic aligner as requiring further inspection by a technician based on determining that the orthodontic aligner comprises the manufacturing flaw.

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.

Abstract: An apparatus includes a probe sized to be at least partially inserted into an intraoral cavity of a patient and an illumination unit configured to output light. The apparatus includes a light focusing assembly comprising an image space lens, an object space lens and a focus changing assembly between the image space lens and the object space lens and being configured to: overlap a plurality of light beams of the light within the light focusing assembly; and focus the light to a plurality of external focal planes to illuminate the patient's teeth. The apparatus includes a detector 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: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These palatal expanders may be configured to have a variable surface smoothness on one side (e.g., the lingual-facing surface) compared to the opposite side (e.g., the palatal-facing surface). These palatal expanders may be configured to have a varying thickness in the palatal region. These palatal expanders may be adapted for ease in removal by the patient or caregiver (e.g., including a hinged region and/or detachment region, and/or including a thinner buccal side then occlusal side, etc.).
