A mandibular advancement device for stabilizing and exercising muscles that support the human jaw and for improving chewing and biting function. The mandibular advancement device includes a base portion and two curved members extending outwardly from the base portion to form a generally arched-type shape. The device also includes two axles wherein each axle extends inwardly from a portion of each of the curved members. The device also includes two rollers, wherein each of the rollers is slidably disposed upon each of the axles for engagement by human teeth to achieve mandibular advancement.

A therapeutic device may include an upper section and a lower section. The upper section may include a hyperboloid having a top end and a bottom end. The lower section may have a tubular configuration and the lower section may be connected to the bottom end of the hyperboloid. The tubular lower section may extend longitudinally from the upper section. A first aperture may may be disposed in the upper section and/or the tubular lower section. A measurement scale may be included on the tubular lower section. One or more textured sections may be disposed on the tubular lower section.

A therapeutic device may include an upper section, which may include an aperture, and a lower section, which may be connected to a bottom end of the upper section. The lower section may extend generally longitudinally from the upper section. The therapeutic device may include one or more textured sections on at least a portion of the upper section and/or the lower section. The therapeutic device may include a measurement scale disposed on at least a portion of the upper section and/or the lower section, and the measurement scale may span at least a portion of a length of the upper section and/or the lower section.

The present invention relates to a device and method for the treatment of trismus. The device comprises: a frame including two arms connected to a base portion; a first insert locatable in the frame, the first insert configured to cause the two arms to exert a first predetermined force in opposing outward directions relative to a central axis of the device; a second insert locatable in the frame in the same position as the first insert, the second insert configured to cause the two arms to exert a second predetermined force in opposing outward directions relative to the central axis of the device.
