  • Prescription required

Atos Medical TheraBite Jaw Motion Rehabilitation System is a clinically proven, anatomically correct, and portable system designed to restore mobility after trismus and mandibular hypomobility. The patient-controlled system utilizes repetitive passive motion to stretch connective tissue, strengthen weakened muscles and mobilize joints. The average sustainable gain in jaw opening is around 1–1.5mm per week. TheraBite Device can also help to reduce muscle pain by reducing joint inflammation and preventing reduced muscle strength during (chemo) radiation in the head and neck area.

Atos TheraBite Jaw Stretching Device Features

  • Anatomically correct: A unique feature of TheraBite Device is its ability to follow the naturally curved motion of the jaw. The curved track of the TheraBite Jaw Mobilizer guides the mandible along an anatomically correct pathway.
  • Patient controlled: When using the TheraBite system, the patient is in control. Speed and opening range can be adjusted directly by the patient, using manual force, or the Fine Adjustment Knob. This feature helps to reduce anxiety levels and improve compliance.
  • Portable: The TheraBite system is durable and lightweight. It can be conveniently stored in the Carrying Bag provided for patients to continue their rehabilitation program wherever they go.
  • Load-bearing comfort: The mouthpieces are attached to the Jaw Mobilizer and are designed in such a way that the load-bearing forces of stretching spread across the teeth. This, together with the Bite Pads, promotes a comfortable and even stretch while protecting the patient’s teeth.
  • Effective: Passive motion and stretching exercises with the TheraBite system are clinically proven to be an effective form of jaw therapy. It has been used with success by thousands of patients suffering from more than 30 different conditions, ranging from postradiation Trismus to orofacial pain.
  • For all ages: The TheraBite Jaw Motion Rehabilitation System is available in both adult and pediatric versions. The pediatric version has smaller mouthpieces that are more suitable for patients with a smaller mouth.

What is TheraBite Therapy Treatment used for?

  • Increasing the range of motion of the jaw
    • Stretches connective tissue: Fibrous scar tissue causes tightening of muscle and joints and requires stretching to re-align the collagen fibers within. Passive and repetitive stretching can help to lengthen and reform these fibers and does so in an anatomically correct fashion.
    • Strengthens weakened muscles: Muscles that have suffered from disuse atrophy require strengthening across the full range of motion. Using passive range of motion exercises, the TheraBite system 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.
    • Mobilizes joints: 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.
  • 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.
    • Reduces muscle 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 has been proven to reduce joint and/or muscle pain in as little as two weeks of therapy.
