BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is an oral device. More specifically, the present invention is an oral function device.
Description of the Related Art
People such as children or adults because of developmental problems (e.g., cerebral palsy, Down's syndrome) or an acquired injury (e.g., a head injury or a stroke) may experience a loss of their oral-motor function (e.g., failure or loss of previous abilities to chew food or eat, failure or loss of abilities to swallow, or failure or loss of abilities to speak).
The ability to control the lower jaw is the foundation of many human's most significant abilities (e.g., feeding, speech, swallowing and respiration). As babies start to develop their feeding skill from sucking milk, to suckle, and then to munch food at the age of six to seven months, and then start to develop some vertical jaw movement and biting at the age of twelve months, and start to develop some lateral jaw movement at the age of eighteen to twenty-four months and by the age of thirty-six months, most children may develop mature rotary jaw movement and manage most solid food easily. From a developmental point of view, some children have failed to achieve these developmental milestones and feeding skills because of inadequate basic foundation oral-motor skills (e.g., weak mastication muscle strength and inadequate lower jaw's mobility and stability).
The present invention may solve the aforementioned problems of delay in mastication such as inadequate strength, range of motion of lower jaw and lack of appropriate experience of lower jaw in different directions of movement.
BRIEF SUMMARY OF THE INVENTION
The present invention is an oral device. More specifically, the present invention is an oral function device.
The oral function device is to solve problems associated with a delay in mastication such as inadequate strength, range of motion of lower jaw and lack of appropriate experience of lower jaw in different directions of movement. The oral function device is made of non-nutritive and non-toxic resilient tubing. The tubing is placed under the crushing molar teeth in either a sagittal plane or a coronal plane according to the direction of lower jaw movement training. Therapists instruct client to chew on this tube in multistep, progressive and rhythmic chewing in an up and down, left and right or front and back manner.
The oral function device includes an elongated hollow handle having a first end and a second end and a first opening and a second opening, the first opening is disposed on the first end of the elongated hollow handle and the second opening is disposed on the second end of the elongated hollow handle, the elongated hollow handle includes a flange disposed around the first opening of the elongated hollow handle and an elongated chew piece removably inserted into the first opening of the elongated hollow handle, the elongated chew piece rotates freely inside the elongated hollow handle. The oral function device also includes an end plug inserted into the second opening of the elongated hollow handle, the end plug include a base, an extension and a protruding attachment tab, the extension is coupled to a center of the base, the extension has a top curved prong and a bottom curved prong, the top curved prong includes a protruding attachment tab, the top curved prong and the bottom curved prong are made of pliable material, the protruding attachment tab corresponds with the aperture disposed adjacent to the second end of the elongated hollow handle, the top curved prong and the bottom curved prong bend while inserted into the second end of the elongated hollow handle, the protruding attachment tab securely snaps into place within the aperture disposed adjacent to the second end of the elongated hollow handle and the protruding attachment tab is depressed to release the end plug from the elongated hollow handle; and
It is an object of the present invention to provide an oral function device that improves the dissociation of a user's jaw with multidimensional exercises for dynamic movements.
It is an object of the present invention to provide an oral function device that offers three directions of lower jaw training and a combination of either up and down and left and right of lower jaw training or up and down and front and back of lower jaw training.

The second graph 620 may illustrate a plurality of predicted motion paths during mature chewing. The second graph 620 may have an x-axis 622 and a y-axis 624. The x-axis 622 may represent horizontal side-to-side jaw motion during chewing. The y-axis 624 may represent vertical up-and-down jaw motion during chewing. The second graph 620 may illustrate a consistent rotary motion, which is characteristic of mature chewing.
The oral function device may be made of three parts, an elongated hollow handle, an end plug and an elongated chew piece. The elongated chew piece may have a wave shaped appearance tube. The elongated chew piece may be inserted into the hollow cylindrical handle. The elongated chew piece may rotate freely inside the hollow cylindrical handle. The end plug may be fixated to the elongated chew piece and prevent it from falling off of the elongated hollow handle. A flange may be designed in front of the elongated hollow handle to prevent child users from putting the elongated chew piece too far into their mouth.
Use of the oral function device is straightforward. For the combination of training the lower jaw in up and down and left and right directions, a user may put the oral function device in a sagittal plane. The oral function device may be placed in a crushing molar in a sagittal plane. When the lower jaw may be closed or is elevated, the elongated chew piece may give a resistive force to the mastication muscles to help to strength the mastication muscles. The user's teeth may depress on the elongated chew piece which may rotate freely, and that rotating elongated chew piece may provide a sheering surface or unstable surface that may deviate the lower jaw from exclusive vertical up and down movement and encourage the jaw moving laterally (i.e., side to side movement). The combination of training lower jaws in up and down, and front and back directions, may include putting the oral function device in a coronal plane. The oral function device may be placed under a crushing molar in the coronal plane. When the jaw closes, it may give a resistant force to the mastication muscle that elevates the lower jaw (i.e. closing the jaw), to strengthen matriculations muscles in an up and down direction. The user's teeth may depress on the elongated chew piece that may rotate freely and provide a sheering surface or unstable surface which may deviate the lower jaw from exclusive vertical up and down movement and encourage the lower jaw moving in a front and back direction.
The oral function device may improve the jaw s movement in three dimensions (i.e., up and down, left and right, and front and back). As explained in the following research, the lower jaw is travelling in a tear-drop shape as age matured. Therefore, the oral function device when placed in sagittal and coronal plane, may help improving the jaw movement in a three dimensional plane (i.e. up and down, left and right, front and back). And the oral function device may facilitate the natural developmental changes of movement of the lower jaw.
While the present invention has been related in terms of the foregoing embodiments, those skilled in the art will recognize that the invention is not limited to the embodiments described. The present invention can be practiced with modification and alteration within the spirit and scope of the appended claims. Thus, the description is to be regarded as illustrative instead of restrictive on the present invention.
