Disclosed herein is mouth guard including a structural component having an arch portion including pre-formed tooth-receiving indentations; and a conforming component supported by the structural component and being displaceable between the teeth of a wearer and the tooth-receiving indentations only when at or above a threshold temperature. Also disclosed is a computer-implemented method for recommending a mouth guard, and a computer-implemented method for determining bite dimensions for each of a plurality of mouth guards.

An intraoral scanner includes a probe with a sensing face, patterned light sources that are coupled to the probe, un-patterned light sources coupled to the probe, near infrared (NIR) light sources couple to the probe, cameras coupled to the probe, and a processing device coupled to the probe. The processing device is configured to control an operation of the patterned light sources, the un-patterned light sources, and the NIR light sources.

A system employing projected light upon objects or surfaces to determine a safe light wave length range of light to be emitted for treatment of the object or surface is provided. Light emitters are employed for projecting light waves upon the surfaces along with light reception components which are employed to receive reflected light wave ranges from such emitted light. Thereafter, a safe light wave range can be employed to treat or affect the object or surface.

A method of multimodal scanning may include generating surface scan data of an intraoral structured using structured light. The method may include generating volumetric scan data of an internal structure of the intraoral structure with OCT scanning. The OCT scan data may be aligned with the surface scan data. A three-dimensional volumetric model of the patient's dentition may be generated based on the aligned OCT scan data and the surface scan data.

A dental hand-held device (100), including a curing device (101) for curing a dental restauration material (103) with light in a first wavelength range; and a fluorescence excitation device (105) for exciting fluorescence of dental substance (107) with light in a second wavelength range.

A method for generating a 3D image includes driving structured light projector(s) to project a pattern of light on an intraoral 3D surface, and driving camera(s) to capture images, each image including at least a portion of the projected pattern, each one of the camera(s) comprising an array of pixels. A processor compares a series of images captured by each camera and determines which of the portions of the projected pattern can be tracked across the images. The processor constructs a three-dimensional model of the intraoral three-dimensional surface based at least in part on the comparison of the series of images. Other embodiments are also described.

A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

A method and device for multimodal imaging of dermal and mucosal lesions. The method includes using at least two imaging modalities from which one is a 3D scan of the lesion, and, additionally providing information on the distance and angulation between scanning device and the dermis or mucosa and mapping at least the second modality over the 3D data.

Systems and methods for automating the production of dental aligners is disclosed. In some embodiments the systems and methods include a three-dimensional printer in communication with one or more computer and one or more computer programs. The system and method configured to permit persons to automatically scan and upload a pre-existing digital scan, x-ray, physical mold or other impression of a person's teeth to the three-dimensional printer for direct real-time printing of custom dental aligners. In some embodiments, the system and method also includes an intraoral scanner configured to permit persons to take and receive a real-time digital scan of their teeth and receive a real-time custom dental aligner, on the same day and from the same integrated system, method, machine, kiosk and location.

Methods for generating multiple orthodontic treatment options for a digital 3D model of teeth in malocclusion. The method generates a plurality of different orthodontic treatment plans for the teeth and displays in a user interface the digital 3D model of teeth in malocclusion with a visual indication of each of the plurality of different orthodontic treatment plans. The visual indication of the treatment plans can be overlaid on the digital 3D model of teeth in malocclusion and possibly include aligners, brackets, or a combination of aligners and brackets. A doctor, technician, or other user can then select one of the treatment plans for a particular patient.
