Trismus Rehabilitation Device
The Dynasplint® Trismus System aids in restoring physical function and more importantly, quality of life to patients suffering from joint stiffness and limited range of motion in the posterior mandibular or temporomandibular region. Limitations in mandibular motion can be caused by TMJ dysfunction, radiation therapy, infection, surgery, trauma, or burns. In preliminary clinical trials the Dynasplint® Trismus System has been successful in treating these limitations. The key to its effectiveness is the low-load, prolonged-duration stretch (LLPS) technology that delivers a correct biological stimulus to create a permanent length change in shortened connective tissue.

Features & Benefits
- The Dynasplint® Trismus System uses a low-load, prolonged-duration stretch (LLPS) to deliver a correct biological stimulus that creates a permanent length change in shortened connective tissue.
- 10.8 million people of all ages in the United States suffer from TMJ (estimate from the National Institute of Health) Limitations of mandibular motion can be caused by TMJ dysfunction, facial trauma, radiation therapy, stroke and surgery.
- A Dynasplint® Systems consultant will fit patients and oversee their treatment to ensure the best possible results.
- Dynasplint® Systems have been clinically proven to reduce time and cost associated with range of motion rehabilitation—in many cases by more than 50 percent.*
- Over a quarter of a million patients have been successfully treated with Dynasplint® Systems.

Frequently Asked Questions:
What is Trismus?
Trismus is an involuntary contraction of the jaw muscles (muscles of mastication) causing a restriction of mouth opening. This occurs when the connective tissue becomes tight and short. Serious health implications include: inability to chew and digest food properly, difficulty speaking and compromised oral hygiene.
Who is appropriate for the Dynasplint® Trismus System?
Patients who have range of motion limitations in the facial muscles or jaw area are appropriate for the device. Limitations can be caused by: TMJ dysfunction, arthritis, fractures, trauma, infection, head and neck surgery, oral surgery, radiation therapy or burns.
When can patients start using the Dynasplint® Trismus System?
The patient can begin using the Dynasplint® Trismus System as soon as the doctor releases them for passive range of motion. After onset, injury or surgery, the sooner the device is applied the faster results can be expected.
When is the Dynasplint® Trismus System applied?
The Dynasplint® Trismus System was developed for home use. It is suggested patients use the device 3 times a day for up to 30 minutes per session, 7 days a week.
Where is the Dynasplint® Trismus System applied?
The device is worn inside the middle of the mouth while the patient is relaxed. Proper placement is essential for the ideal stretch of the masticatory muscles. The patient can hold the device with their hand or attach the counterbalance bars for hands-free therapy.
Why should a doctor choose a Dynasplint® Trismus System?
The Dynasplint® Trismus System is the most advanced home therapy treatment available. It is far superior to the commonly used tongue depressors and other systems. The Dynasplint® Trismus System actively stretches the muscles of the face and can be used for patients with openings as small as 9mm. Patients find it easy and comfortable to use.
How does the Dynasplint® Trismus devicework?
The device is based on low-load, prolonged-duration stretch (LLPS) technology. It is spring loaded for simple, adjustable, reproducible tension at each therapy session. This correct biological stimulus has been proven to permanently lengthen shortened connective tissue.
How Do I Get a Dynasplint® System?
All Dynasplint® Systems are available by prescription/certificate of medical necessity only. Ask your doctor or therapist to prescribe one for you if medically indicated to help increase your range of motion.
Print the brochure and certificate of medical necessity of this Dynasplint® System and take it to your doctor or therapist.
