    This animation was prepared by BiteFX to show the etiology of Jaw and Muscles Sprain/Strain (JAMSS) that sometimes can occur from a longer dental procedure, or for a patient who has a limited range of motion as an existing condition. As with other joints in the body, there are 4 grades of joint mobility:

    1. Normal resting range of motion (teeth apart, tongue up)

    2. Normal active range of motion (25 to 45 mm)

    3. Maximum voluntary range of motion (45 to 60 mm)

    4. Maximum involuntary range of motion (by application of a bite block, your hand or tool resting on the mandible.)

    While the jaw joint and musculature are highly adaptable, in some instances the muscles become hyperactive and are in conflict when the lateral pterygoid is required to hold the jaw open on a sustained basis. This video demonstrates what can happen in cases of delayed onset of JAMSS. It is important that your staff be informed of this condition and encourage patients to call your office immediately if this occurs, rather than wait and go to Urgent Care.
