An improved manual oral cavity expansion device comprising a fixing element with one end connected with a first holding element, and another end forming an accommodating portion protrudingly disposed with a pivoting portion; at least one linkage element disposed on the fixing element; a rotating element accommodated in an accommodating space of the accommodating portion and sleeved on the pivoting portion; a movable element with one end connected with a second holding element, and another end forming a movable portion correspondingly disposed in the accommodating space and sleeved on the pivoting portion; and an expansion unit. An outer circumference of the rotating element is arranged with a plurality of tooth elements in a row, and one end of the linkage element contacts the tooth elements. The expansion unit has a first expansion arm connected to the accommodating portion and a second expansion arm connected to the movable portion.

A device for enhancing the appearance of a person's lips is formed from a curved member configured to fit between the person's upper or lower lip and an adjacent gum at the front of the mouth. The curved member has a gingival portion configured to be placed on the person's gums, a top surface and an extension connected to the top surface and extending from a longitudinal edge of the top surface to overlap and extend beyond the gingival portion. The extension is configured to rest against and evert the person's upper or lower lip when the device is placed between the lip and the person's gum.

Embodiments of the innovation relate to a jaw range of motion device that includes a conical base having a first end and a second end and a helical ridge carried by the conical base and disposed between the first end and the second end. The helical ridge and the conical base define a channel between adjacent helical ridge portions. The jaw range of motion device also includes a handle disposed at the second end of the conical base. When a user inserts the jaw range of motion device between his teeth, the user can apply a self-directed manual force to the device by generating a twisting motion on the handle to provide an incremental jaw range of motion.

Disclosed is a tongue strengthening device that includes a handle on one end and a bulb structure on the other end. The bulb is resiliently flexible, and enables a user to exercise their tongue by repeatedly compressing and releasing the bulb. Provided is a system or kit that includes multiple tongue strengthening devices having different compression specifications that allow a patient to graduate to devices which are harder to compress as the patient gains tongue strength.

A tongue strengthening device includes an intraoral bolus simulator having a sensor input component. An extraoral user interface is connected to the intraoral bolus. The intraoral bolus simulator is moveable relative to the extraoral user interface in response to a movement of a user's tongue. The sensor input component is configured to detect a pressure or force applied to the intraoral bolus simulator and/or to detect movement of the intraoral bolus simulator relative to the extraoral user interface.

An improved hand tool with molar as resistance point comprises a holding unit, a pivoting unit, an expansion unit and a clean jacket. The holding unit has a first end and a second end. The first end is provided for holding by a user, and the pivoting unit is pivotally connected to the second end correspondingly. A butt end and a connection end are respectively formed at two ends of the expansion unit, the butt end correspondingly butts a plurality of molars of the user, the connection end is pivotally connected to the pivoting unit correspondingly, and the clean jacket is correspondingly sleeved on the expansion unit.

Various embodiments are directed to systems and methods for evaluating jaw movement characteristics of a user, for example, in a plurality of distinct jaw motion directions. In an example implementation, a jaw exercise system as discussed herein is configured to facilitate the exercise and/or quantification of a user's jaw strength in at least one of six distinct directions. As described herein, the jaw exercise system may comprise a frame assembly to which a user may selectively attach one of a plurality of an interchangeable functional assemblies, each configured to facilitate the evaluation of the jaw movement characteristics of a user in six jaw movement directions. The jaw exercise system comprises one or more of a progressive resistance attachment assembly, a passive motion attachment assembly, a force characterization attachment assembly, and a hyoid motion attachment assembly.

The training device for chewing and swallowing can be used by patients who have difficulty chewing and/or swallowing to assist them to learn how to chew and swallow. The device includes a bolus delivery cylinder and a plunger. The bolus delivery cylinder can include a cylindrical housing having a peripheral wall and a hollow interior. The plunger can be slidably received in the cylindrical housing and secured thereto. In some embodiments the peripheral wall can be perforated. The interior of the housing is configured to accommodate small pieces of food. The bolus delivery cylinder can be made from a transparent, flexible material, such as silicon.

A carrying case has first and second clam shell members hingedly connected along one side thereof and defines a interior cavity when in a closed position. At least a portion of an oral device is disposed between the first and second clam shell members with a support member engaging and supporting the oral device such that an intraoral bolus simulator is suspended in the interior cavity free of any engagement with the carrying case. The intraoral bolus simulator may include lubricated patches transformable from a first state, wherein the lubricated patches each comprise water soluble thermoplastic particles suspended in a silicone matrix, to a second state, wherein the water soluble thermoplastic particles are depleted from the silicone matrix. A method of stimulating an oral cavity includes depleting the water soluble thermoplastic particles from the silicone matrix, and presenting a rough surface to the user with the depleted lubricated patches.

A personalized device for therapeutic training includes a therapeutic device body, electronic circuitry integrated into the therapeutic device body wherein the electronic circuitry comprises at least one sensor. The therapeutic device body is personalized for use by a patient through sizing and shaping the therapeutic device based on measurements of the patient and 3D printing at least a portion of the therapeutic device body and at least a portion of the electronic circuitry to make the personalized device both electrically and mechanically functional.
