Products  /  TMD Physical Therapist                                 

 The Isences® TMD Physio Care is a medical-grade jaw rehabilitation device designed for physiotherapists treating temporomandibular disorders (TMD), trismus, and jaw stiffness.
Using inflatable functional elements, it creates a natural biaxial rotational–shear jaw movement that restores mobility while protecting the temporomandibular joint (TMJ) from excessive load.

·         Ideal for gentle strengthening and mobility exercises, the device helps improve mouth opening, chewing efficiency, and pain reduction.
It also supports post-stroke dysphagia therapy by promoting safer swallowing and muscle coordination.

Manufactured for single-patient, multiple use, the Isences® TMD Physio Care is available in single- and double-belly models to fit various rehabilitation needs.
A trusted choice for TMD physiotherapy, jaw muscle training, and clinical recovery programs.

Dimensions in the Oral Cavity

• Withdrawing 10 ml of air from the device (using a syringe) allows insertion when the mouth opening is limited

              to approximately  15 mm.

·         Inflating with up to 14 ml *of air enables the user to achieve a maximum mouth opening of approximately 32 mm**.

 

(When used according to the recommended air volume*, the device maintains effectiveness for more than 3K exercise cycles.)

  (**Approximate measurements. Actual results may vary with individual anatomy and clinical progress.)         

                                   

    Functional /  dynamic force specifications

• Functional amplitude of Jaw opening exercises up to 17 mm.
• The force of Jaw stretching exercises is up to 18 Newtons (N) (see Fig.1).
• Jaw strengthening exercise force up to 22 N depending on the amount of air injected into the device and the bite amplitude

( see Fig.2).

            (When used according to the recommended air volume and bite amplitude, the device maintains effectiveness for more than 3K exercise cycles.)

Clinical-grade, user-safe recommendation set for an individual using a Jaw Device
These are designed to guide home or clinic-based use under professional supervision, aligning with safe intensity and duration principles from evidence-based TMD rehabilitation literature.

Mobility Training (Gentle Stretching for Range of Motion)

Purpose:

Restore functional, pain-free mandibular movement and improve joint and soft tissue extensibility.

Technique:

• Sit upright in a comfortable position, keeping your shoulders relaxed and your head in a neutral, balanced posture.
• Gently open your mouth and place the jaw exerciser so that its end rests over your molar teeth.

If mouth opening is limited and placement is difficult:

• Withdraw the recommended volume of air from the device using the syringe to reduce its size and allow easier insertion.

If the exerciser was inserted after partial air withdrawal:

• Detach the one-way stopcock from the syringe before beginning the exercise. This allows the device to refill naturally with air to match your current mouth opening range.
• Once the exerciser expands to your comfortable limit, reconnect the syringe and gradually re-inflate the device, adding small amounts of air at 3–5 second intervals, until you feel a gentle stretching sensation—never pain.

After reaching the desired stretch:

• Close the stopcock to maintain the air pressure and hold the stretch for 10–15 seconds.
• When complete, open the stopcock and slowly release the air before removing the exerciser.

Dosage:

• Repetitions: 3–5 per session
• Frequency: 3–5 sessions daily
• Intensity: Mild tension only (approximately 3/10 effort on a subjective scale)
• Progression: Gradually increase stretch duration to 15-20 seconds after 1–2 weeks if no discomfort occurs.

Safety Note:

Do not overextend or make sudden, forceful movements.
If you feel soreness or stiffness after using the device for over an hour, try gentler movements or reduce how often you exercise.

Stability Training (Controlled Strength & Neuromuscular Coordination)

Purpose:
To improve muscular control, symmetry, and joint stability during mandibular movement.

Technique:

• Inflate the exerciser with the recommended 3 mL of air, then close the  one-way stopcock to maintain internal pressure.
• Gently bite down on the exerciser so that the front teeth move toward contact within a small, controlled range of 1–5 mm*.
  This motion produces a moderate isometric load (approximately 6–18 N), suitable for initial strengthening and coordination training (see Fig.2 )
• For progressive resistance, increase the air volume to 5 mL.
  This adjustment generates approximately  8–22 N of resistance, allowing controlled isometric exercise with a 1–5 mm* movement amplitude of the front teeth (see Fig.2 ).

Throughout the exercise:

• Maintain smooth, symmetrical jaw motion—avoid clenching or abrupt force.
• Ensure there is no pain or discomfort in the joint or muscles.
• Focus on steady muscle engagement and precise control rather than maximal effort.

Dosage:

• Intensity: Submaximal (approximately 15–30% of maximal effort)
• Hold time: 5 seconds per contraction
• Repetitions: 5–10 per session
• Frequency: 1–2 sessions daily

Safety Note:
All movements must be controlled and symmetrical. Discontinue exercise if pain, clicking, or joint locking occurs.

Balancing Flexibility and Strength

Purpose:
To maintain balance between joint mobility and muscular stability, ensuring efficient, coordinated jaw function.

Guideline:

• Sequence: Perform mobility (stretching) first, followed by stability (strength) exercises.
• Stretching improves range of motion; strengthening stabilizes the joint within that new range.
• Excessive stretching may increase joint laxity, while overemphasis on strengthening may cause stiffness or muscular tension.

Integrated Session Example:

• Gentle jaw stretch × 3 repetitions (5-7 seconds each)
• Isometric resistance × 5 repetitions (5 seconds each direction)
• Relaxed closing with light facial massage for 1–2 minutes

General Safety and Customization

• Pain-free rule: Exercises should remain within a comfortable range; avoid any painful movement.
• Post-exercise response: No persistent pain, swelling, or stiffness should last beyond 6 hours.
• Posture: Maintain an upright, relaxed posture; avoid leaning forward or clenching.
• Environment: Perform exercises in a calm, quiet setting to minimize muscle tension.
• Progression: Only increase resistance or mouth opening under professional supervision.

Post-Trauma or Post-Surgical Situations

• Recent facial, jaw, or TMJ trauma
• Post-surgical phase without clinician clearance (e.g., after orthognathic or implant surgery)

• Rinse again with clean water to remove any detergent residues.

 Disinfection

• Wipe clean with a damp cloth or disinfectant wipe after each session.
• Allow the device to air-dry completely before storage or reuse.
• Do not autoclave or expose the device to high temperatures, as this may damage the material.

 Inspection and Maintenance

• Inspect the device before each use for cracks, leaks, or deformation.
• Check the air valve and tubing for secure sealing and smooth operation.
•  Replace the exerciser if you notice any signs of wear, air leaks, or tearing of the material.
