TheraBite Jaw Motion Rehabilitation System can help in lowering muscular pain by minimizing joint inflammation and preventing muscle weakness during (chemo)radiation in the head and neck area. One of the unique feature of TheraBite system is its ability to follow the naturally curved motion of the jaw. The TheraBite Jaw Mobilizer's curved track guides the mandible (lower jaw) along an anatomically correct path.
TheraBite Jaw Motion Rehab System is a medical device that helps in the rehabilitation of jaw movement and provides treatment for a variety of conditions affecting the jaw and surrounding areas. It is especially useful for people who have trismus, a disorder that causes limited mouth opening or pain when opening the mouth and mandibular hypomobility. Clinically proved to be effective. It is portable and uses repetitive passive motion to stretch the tissues and strengthen weaker muscles and mobilize joints. The average weekly gain in jaw opening is roughly 1-1.5 mm.
TheraBite Jaw Mobilizer is a jaw therapy device that is anatomically correct, effective, portable, and user-controlled. It is long-lasting, lightweight, and comes in adult and pediatric sizes.
Features of Therabite Jaw Exerciser:
- Portability: TheraBite is both strong and lightweight. It can be carefully stored in the included Carrying Bag to continue the rehabilitation program even on the go.
- Anatomically correct motion: The capacity of the TheraBite system is to follow the jaw's naturally curved motion. The curving track of the TheraBite Jaw Mobilizer guides the mandible along an anatomically correct path.
- User controlled therapy: TheraBite is controlled by the user. The user can directly control the speed and opening range by using physical force or the Fine Adjustment Knob. This function helps in anxiety reduction and compliance.
- Load-bearing comfort: The mouthpieces are designed to spread the load-bearing stresses of stretching over the teeth and are attached to the Jaw Mobilizer. This, along with the Bite Pads, ensures a comfortable, equal stretch while protecting the teeth.
- Effectiveness: Passive motion and stretching exercises using the TheraBite Jaw Mobilizer have been clinically proven to be a useful method of jaw therapy. It has helped thousands of people suffering from illnesses ranging from post-radiation trismus to orofacial pain.
- For all ages: TheraBite system is available in adult and pediatric sizes. The pediatric variant has smaller mouthpieces that are better suited to those with smaller jaws.

TheraBite Therapy:
Numerous clinical trials have demonstrated the effectiveness of the TheraBite system, which is designed to achieve two treatment goals:

1. Increasing the jaw's range of motion
- Stretches connective tissue
Fibrous scar tissue causes tightening of muscles and joints and requires stretching to realign the collagen fibers. Passive and repetitive stretching can help to lengthen and reform these fibers in an anatomically correct fashion.
- Strengthens weakened muscles
Muscles that have suffered from disuse atrophy require strengthening across the full range of motion. Using a passive range of motion exercises, TheraBite can help to increase muscle mass and endurance. The device can also be squeezed gently to provide resistance while closing the mouth to strengthen the muscles.
Joints that are immobilized can undergo degenerative changes in a matter of days. Passive repetitive motion, such as that provided with the TheraBite system, can help to mobilize the temporomandibular joint across its full range of motion via passive motion.

2. Pain reduction
- Reduces joint inflammation
Immobilized joints lead to thickening of the synovial fluid and thinning of cartilage. This stiffening of the joints ultimately leads to inflammation and pain. Passive motion of the joint, such as that provided with the TheraBite system, can activate anti-inflammatory agents that promote joint lubrication and reduce inflammation and pain.
Muscle pain (myofascial pain) is usually caused by inflammation, which creates abnormal pressure on nerves, muscles, and bones. This inflammation process can be corrected through passive motion exercises. Passive motion and stretching with the TheraBite system have been proven to reduce joint and/or muscle pain in as little as two weeks of therapy.
