An oro-facial exerciser apparatus for exercising and training the muscles of the lips and cheeks of a user's face, utilizes a pair of legs that are pivotally connected together to pivot between a substantially closed together state and a splayed apart state. The legs each have a proximal end proximate the pivot and a distal end remote from the pivot having a mouth mounting formation to mount the distal end to a respective opposing location of the user's mouth and the exerciser further has a resilient biasing means between the legs to bias them towards a splayed state and thereby provide a resistance force against which the user's lips and/or cheeks press in use for exercising and training the muscles. The resilient biasing means are demountably mounted on the legs, enabling them to be replaced with an alternative biasing means for altering the resistance.

The mouthpiece includes an enhanced mouthpiece, a data sensor, and a personal data device. The data sensor collects data regarding the bite force, the number of bites and the duration of each bite. The data sensor wirelessly transfers the collected data to a personal data device.

The various devices and systems herein include oropharyngeal exercise devices having a pump bulb with a bulb body having a flow restriction structure with a restricted configuration in which the flow restriction structure is configured to restrict the flow of fluid through the lumen such that the user must apply a force to increase the flow of the fluid. Other devices include containers and/or lids thereof with the bulbs attached to or integrated therein.

The purpose of the present disclosure is to provide a tongue exercise apparatus for snoring prevention, wherein the apparatus can be useful for exercising the tongue in order to prevent snoring. A tongue exercise apparatus according to the present disclosure is a tongue exercise apparatus that a user can hold by hand and use to perform tongue exercises, the apparatus comprising: a handle which the user can hold by hand; a tooth engagement part which extends from the end of the handle and has an engagement groove that can engage with the ends of the teeth of the user; and an exercise assistant part which is connected to the tooth engagement part so as to be able to enter the mouth of the user, and has a protrusion portion that protrudes, in a direction intersecting with the direction in which the tooth engagement part extends from the handle, so that the tongue of the user can contact the protrusion.

According to the present disclosure, an oral rehabilitation device includes an air bladder and a pumping member. The air bladder includes a cheek-side membrane and a teeth-side membrane, and the cheek-side membrane and the teeth-side membrane are arranged opposite to each other. The pumping member is communicated with the air bladder, and the pumping member is configured for inflating the air bladder. The cheek-side membrane and the teeth-side membrane extend toward the outside of the air bladder when the pumping member is inflating the air bladder, and an extension of the cheek-side membrane is larger than an extension of the teeth-side membrane.

Maxillary and mandibular appliances can be mounted to a user's upper and lower jaws. The appliances can include a palatal pad, buccal tubes, hamular notch tubes, and an anterior deprogrammer. The various portions of the appliances can provoke beneficial reactions by muscles in the tongue and jaw area, massage the same muscles, or provide other beneficial effects.

A method includes: acquiring chewing/swallowing information from a sensing device installed on a user, wherein the chewing/swallowing information is related to chewing of the user when the user eats a first printed food; determining based on the chewing/swallowing information, a number of chews made by the user, and determining based on a first print pattern and the number of chews, a second print pattern for a second printed food to be created by a food printer; and transmitting print control information to the food printer via a network, wherein the print control information is used for causing the food printer to create the second printed food using the determined second print pattern.

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 is described that can effectively increase the range of motion of a jaw of a patient to address physiological conditions that involve restricted range of motion of the jaw of the patient. The device can be used to apply opposing forces to the maxillary and mandibular teeth, which can stretch the temporomandibular joint and mandibular muscles, which in turn can aid in opening of the jaw. Furthermore, the device includes a spring, which is configured to be stretched when the patient performs mastication motions. Such stretching of the spring dynamically applies varying amounts of force on the jaw depending on the position of the jaw during the entire range of motion of the jaw, and severity of the physiological condition such as trismus. Such dynamic force requires the jaw to perform different amounts of work at various positions, which aids in the opening of the jaw.
