An oral fixation apparatus according to an embodiment of the present disclosure includes a mouthpiece provided to be mounted in a mouth, and a pressing unit configured to move relative to the mouthpiece, wherein the pressing unit is configured to press a tongue in the mouth to any one side in the mouth. Through this configuration, the oral fixation apparatus may maintain the same intraoral state. The oral fixation apparatus may be stably mounted inside the mouth, such that radiation therapy may be effectively and stably performed.

Portable operatively simple touch screen apparatus uses testing methods and systems that are free of age and language constraints include special signal processing techniques that provide a temporal resolution highly sensitive for probing cognitive function. The embodiments include or make use of one or more modules implemented at least partially in a set of instructions in software and configured to measure user reaction times to visual stimulus on a touch screen device having a capacitive sensor touch-sensitive surface and a detector of audio waves resulting from touch on the touch-sensitive surface. The modules employ recordation of acoustic vibrations resulting from a user's touching a target location on the touch screen surface spaced from a touched starting location on that surface, in one embodiment, to measure temporal response to a visual stimulus placed at the target location.

An oral appliance that includes tongue positioning structures which are useful in treating snoring, OSA and related disorders. The invention provides a passive tongue location device which includes cavities located on the internal surface adjacent the tongue, the cavities operatively providing a retentive effect on the tongue when it is in its relaxed state. Further, the present invention provides an oral device adapted to operatively enhance the operation of a sleeping user's airway, including a carrier adapted to be positioned over at least some of the lower teeth of the user and having an interior projection over at least part of the gums of a user, the projection defining a pair of opposed cavities, the cavities being shaped and operatively adapted so that the tongue of the sleeping user will passively engage the cavities.

The Surgical Lingual Retractor Plus device is unique because there are not retractors similar to it, either due to its simplification that allows to retract tissue and protect anatomical structures at the same time, it can fulfill the function of suction of fluids and illumination of the surgical area to be treated by the dental professional or other medical professionals. The protection that it provides to the tissues is contemplated by the fact that it is a device made of stainless steel, providing protection against cutting and high-speed rotating instruments. This device will have a grip component, a retraction component and a protection component connected to a suction and lighting system, all with the purpose of being able to perform all the functions at the same time during the surgery, once simplifies the psychomotor actions by the operator (dental or medical professionals).

Certain configurations of removable oral devices are described. In some instances, the removable oral device includes a palatal element. In certain configurations, the palatal element may comprise a variable hardness at different areas, e.g., edges can be softer than other areas of the removable oral device. In other instances, the removable oral device may comprise two or more individual palatal elements which together can form the palatal element and permit user adjustment of the oral volume. Various materials used in the palatal element are described. Sensors and other on-board devices are also described.

Dental instrument assemblies (e.g., mouth pieces, bite blocks, vacuum dental mirrors, illuminated dental mirrors, illuminated dental wedges, trans-illumination dental instrument, illuminated dental bite blocks, etc.) are provided. The dental instrument assemblies may be adapted to be periodically sterilized. The dental instrument assemblies may include a magnetically energetic fiber optic coupler. The magnetically energetic fiber optic coupler may be configured to allow dental instrument adapter to rotate with respect to an associated fiber optic cable that is removably connected to the magnetically energetic fiber optic coupler. The dental instrument assemblies may include a fiber optic material that is encapsulated.
