Tool for tonifying face and neck muscles, extending in a longitudinal direction (X-X) corresponding to the lengthwise dimension of the tool, transverse dimension (Y-Y) corresponding to a widthwise dimension of the tool and vertical direction (Z-Z) corresponding to the thickness of the tool, comprising: a container (10; 110) comprising several single housings (11; 111);a series of weights (20; 120), each singly contained inside a respective housing of the container (10; 110).

The oral training device for muscles of the throat and/or face includes a panel which is receivable in the oral cavity formed between the lips and teeth. The panel has a first face adjacent to the lip area and an opposite second face being adjacent to the teeth and/or gums when in use. The device includes a handle which projects outwardly from the first face for applying an outward pulling force to the panel generally away from the oral cavity. The device also includes an elongate platform extending laterally across the first face onto which the upper and lower lips are placeable when in use.

Devices and methods for training the tongue and other muscles of the throat and upper respiratory airway to alleviate symptoms of snoring and the Obstructive Sleep Apnea Syndrome (OSAS) are provided. A threshold-load trainer, or similar device, having a biased tongue resistance pad is used for strengthening the muscles of the tongue to inhibit narrowing or obstruction of the upper respiratory airway, particularly during a state of relaxation or sleep. The threshold-load trainer embodiments of the subject invention can specifically target the genioglossus muscle under the tongue (the major tongue protruder) and other muscles of the throat and upper respiratory pathway, so as to improve muscle tonus.

In one aspect of the present application, a dental appliance for isolating jaws from facial muscles is provided, the dental appliance is substantially in the shape of an elongated plate curved according to dental arches, and is received between the jaws and the facial muscles when it is worn, the dental appliance comprises: buccal shields located at both ends of the dental appliance and configured to isolate posterior teeth from facial muscles; and labial bumpers located in the middle of the dental appliance and configured to isolate anterior teeth from facial muscles, wherein the buccal shields and the labial bumpers form an integral piece.

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.

A lip muscle strengthening device includes: an upper plate inserted into a mouth of a user including a first electrode formed on a bottom surface; a lower plate inserted into the mouth of the user including a second electrode formed on a top surface; an outer support plate adhered to an outer lip of the user and supporting a front end of the upper plate and a front end of the lower plate in a connected state while separating the upper plate and the lower plate from each other; and a pressure recognition unit connected to the first electrode and the second electrode and enabling the user to recognize a closed state of the mouth when the user pushes the upper plate and the lower plate with the upper lip and the lower lip and the first electrode and the second electrode contact each other.
