A processing device receives, from an image capture device associated with an augmented reality (AR) display, a plurality of images of a face of a patient. The processing device selects a subset of the plurality of images that meet one or more image selection criteria. The selection comprises determining, from the plurality of images, a first image that represents a first position extreme for the face; determining, from the plurality of images, a second image that represents a second position extreme of the face; selecting the first image; and selecting the second image. The processing device further generates a model of a jaw of the patient based at least in part on the subset of the plurality of images that have been selected.

A biometric information detection device according to one embodiment of the present disclosure is configured to be installed in a living body, and includes a sensor, a battery, a mechanical switch, a sealing member, and a holding member. The mechanical switch switches between a conduction state in which power is supplied from the battery to the sensor and a cutoff state in which supply of the power is blocked. The sealing member seals all of the sensor, the battery, and the mechanical switch. The holding member is attached to the living body and holds the sealing member.

An identification apparatus includes an input interface to which position data including position information of each of a plurality of objects is input, and processing circuitry that is configured to identify at least one object among the plurality of objects based on the position data that is input from the input interface and an estimation model that is trained to estimate a type of each of the plurality of objects based at least on the position data of each of the plurality of objects, the position data including a relative positional relationship which is fixed inside the mouth.

A cognitive function evaluation device includes: an obtainment unit configured to obtain speech data indicating speech uttered by a subject; a calculation unit configured to extract a plurality of vowels from the speech data obtained by the obtainment unit, and calculate, for each of the plurality of vowels, a feature value based on a frequency and an amplitude of at least one formant obtained from a spectrum of the vowel; an evaluation unit configured to evaluate a cognitive function of the subject from the feature value calculated by the calculation unit; and an output unit configured to output an evaluation result of the evaluation unit.

Oral appliances and techniques for treating patients having abnormal tongue development using such oral appliances. An oral appliance includes a sheath adapted for placement in proximal to a tongue within a mouth of a patient, wherein a side of the sheath which comes into contact with the tongue when placed in the mouth substantially conforms at least in shape to features of the tongue; and at least one sensor embedded within the sheath, wherein each of the at least one sensor is configured to capture signals indicative of motion of the tongue.

An artificial tongue is provided. The artificial tongue includes tongue tissue formed by a bioprinting process, an antenna embedded within the tongue tissue and configured to wirelessly receive power from an external device, a processor embedded within the tongue tissue and operatively coupled to the antenna, and a piezoelectric element embedded within the tongue tissue and operatively coupled to the processor. The piezoelectric element is configured to deform in response to an applied electric bias, and the processor is configured to cause the electric bias to be applied to the piezoelectric element based on the power received by the antenna.

Provided is a simple, portable, real-time, and in vivo THz imaging device for imaging a target, e.g., a tooth in the subject. Moreover, the scanning based THz imaging device is much sufficiently sensitive as compared with the common X-ray imaging device. Therefore, the scanning based THz imaging device has the potential to operate in the density for early detection problems such as dental caries or demineralization of the enamel in the teeth. Also provided is a method for diagnosing or imaging the target in the subject by using the scanning based THz imaging device of the present disclosure.

A method for remotely assessing oral health of a user of a mobile device by obtaining, using the mobile device (40), at least one digital image (1) of said user's (30) oral cavity (31) and additional non-image data (2) comprising anamnestic information about the user (30). The digital image (1) is processed both using a statistical object detection algorithm (20) to extract at least one local visual feature (3) corresponding to a medical finding related to a sub-region of said user's oral cavity (31); and also using a statistical image recognition algorithm (21) to extract at least one global classification label (4) corresponding to a medical finding related to said user's oral cavity (31) as a whole. An assessment (10) of the oral health of said user (30) is determined based on the local visual feature(s) (3), the global classification label(s) (4) and the non-image data (2).

An image of a dental arch comprising a preparation tooth is generated by an image capture device associated with an augmented reality (AR) display. The image of the dental arch is registered to previous image data associated with the dental arch. A visual overlay associated with a dental prosthetic to be placed on the preparation tooth is generated based on the registering of the image of the dental arch to the previous image data associated with the dental arch. The visual overlay is output to the AR display, wherein the visual overlay is superimposed over a view of the preparation tooth on the AR display.

A wireless implantable neuromuscular stimulator includes an antenna for producing an induced current in response to being disposed in an electromagnetic field. The antenna includes a substrate having an upper surface and a lower surface. An upper coil including a plurality of coil turns is disposed on the upper surface of the substrate. A lower coil including a plurality of coil turns is disposed on the lower surface of the substrate. The upper and lower coils are electrically connected to each other in parallel. The parallel connection can be facilitated by a plurality of connectors that extend through the substrate and electrically connect the upper coil to the lower coil. In one example configuration, connectors connect each coil turn of the upper coil to a corresponding turn of the lower coil.
