Medium-force Jaw Device

The device is designed to enable controlled insertion and progressive mandibular expansion in patients with moderate functional limitation.

• Reduced-volume insertion:
  Withdrawing approximately 20 ml of air allows insertion at a minimal interincisal opening of ~17 mm
• Progressive expansion range:
  Controlled inflation up to ~ max. 17 ml of air supports gradual increase in mouth opening up to ~36 mm

Performance Note

Maintains functional integrity for >3000 exercise cycles when used within recommended air volume parameters

Values are approximate and dependent on individual anatomy and clinical progression

The Medium-Force Jaw Exerciser™ provides moderate, adjustable mechanical loading, enabling progression from mobility-focused to strength-oriented rehabilitation.

Mandibular Movement Amplitude

• Supports controlled jaw-opening exercises up to ~19 mm functional amplitude
  → Facilitates expanded range training with maintained control

Stretching Force - Mobility Training

• Generates up to ~24 N of stretching force
  → Supports advanced soft tissue extensibility
  → Addresses residual stiffness and adaptive shortening

Strengthening Force - Stability Training

Provides resistance up to ~24 N, depending on:

• Air volume
• Bite amplitude

→ Enables moderate-load isometric strengthening
→ Supports improvement of muscle performance and endurance

Load Modulation
Resistance is dynamically adjustable via:

• Air volume (primary control variable)
• Occlusal compression amplitude (secondary variable)

→ Allows graded, patient-specific dosing of mechanical load

Performance Note

Maintains consistent mechanical performance for >3000 cycles under recommended loading conditions

Purpose:

Support gradual improvement in jaw opening, reduce stiffness, and restore comfortable movement.

Step-by-Step
Sit in a relaxed position
Keep your head upright and shoulders relaxed

Place the device
Position it gently between your back teeth (molars)

Adjust for insertion if needed
Remove some air to reduce size if opening is limited

Let the device adapt
Allow it to expand naturally to your current jaw opening

Gradual inflation
Reconnect the syringe and slowly add air every 3–5 seconds, up to a maximum of 17 ml, or until a comfortable stretch is reached.

Reach a gentle stretch
Stop when you feel a moderate, comfortable stretch (never pain)

Hold the stretch
Close the one-way stopcock and hold for 10–15 seconds

Release slowly
Open the stopcock and release air before removing the device

Recommended Use

• Repetitions: 3–5 per session
• Frequency: 3–5 sessions daily
• Intensity: light to moderate
  (approximately 3/10 effort on a subjective scale)

Progression:

Increase hold time to 15–20 seconds after 1–2 weeks if comfortable

Safety Note:

• Stretch should remain comfortable, not painful
• Avoid sudden or forceful movement
• Reduce intensity if soreness occurs
  
  

Purpose:

Improve jaw muscle coordination, control, and joint stability.

Step-by-Step

Set air level
Inflate to approximately 5 ml

Close the stopcock
Maintain internal pressure

Apply controlled bite
Gently bite with small movement (~4–7 mm)

Hold contraction
Maintain for 5 seconds

Relax slowly
Release in a controlled manner

Progression

• Increase air to ~7 ml for higher resistance
• Maintain smooth, controlled movement at all times
  

Recommended Use

• 5–10 repetitions per session
  
• 1–2 sessions per day
  
• Intensity: moderate (15–30% effort)
  

Safety Note

Movements must be smooth and symmetrical

Avoid clenching or excessive force
Stop if pain, clicking, or locking occurs

Purpose
Maintain a healthy balance between mobility and stability for efficient jaw function.

How to Apply
Follow this sequence in each session:

Start with mobility - stretching
Improves range of motion and reduces stiffness

Then perform stability - strengthening
Helps stabilize the jaw within the new movement range

Example Session
Gentle stretch × 3 repetitions (5–7 seconds each)
Isometric resistance × 5 repetitions
(5 seconds each)

Relaxation phase
Close the jaw gently and perform light facial massage for 1–2 minute


Key Tips

Keep all movements controlled and pain-free

Focus on smooth, balanced motion

Progress gradually — not forcefully

Follow These Core Rules
1. Keep all movements pain-free Only perform exercises within a comfortable range → If you feel pain, stop immediately

2. Monitor your response after use

After each session:

• Mild temporary sensation is acceptable
• Pain, swelling, or stiffness should not last longer than ~6 hours
  → If symptoms persist, reduce intensity or stop use

3. Maintain correct posture

• Sit upright and relaxed
  
• Keep your head in a neutral position
  
• Avoid leaning forward or clenching

4. Use a calm environment

• Perform exercises in a quiet, relaxed setting
• Avoid distractions that may increase tension

5. Progress gradually

• Increase resistance or jaw opening step by step
  
• Do not rush progression
  
• For best results, progress under professional guidance
  

Medical Conditions & Recovery Situations

⚠️ Do not use the device unless cleared by a qualified clinician if you have

• Recent injury or surgery (jaw, face, TMJ, or dental procedures such as implants)
• Healing restrictions (fixed or wired jaws, post-surgical recovery phase)
• Serious medical or structural conditions(e.g., tumors in the jaw/face area, severe bone fragility, TMJ ankylosis)
• Neurological or unexplained symptoms
  (persistent pain, numbness, loss of control, or unusual jaw movement)
  

Important
If you are unsure, consult a healthcare professional before use.

Proper care helps ensure safe, hygienic, and long-term use of your device.


After Each Use (Cleaning Steps)

Release air
Remove any remaining air using the syringe port

Rinse thoroughly
Clean under lukewarm running water to remove saliva

Clean if needed
Use mild liquid soap with a soft cloth or brush

Rinse again
Ensure all soap residue is completely removed

Disinfection

Wipe with a clean damp cloth or disinfectant wipe after use

Allow the device to air-dry completely before storing


Storage

Store clean and completely dry
Keep in a protective pouch or case
Avoid moisture, heat, or direct sunlight
