When a Cervical Acceleration/Deceleration (CAD) or Whiplash injury is produced, the head is thrust in the direction of the impact. This violent motion, causing the head to be thrown backwards also causes anterior mandibular displacement as the mouth is forced open
This produces stretching and/or tearing of the ligaments and connective tissues in one or both TMJs, bleeding, and often, displacement of the articular disc in the TMJ
At the moment of impact from the rear, as the head is thrust backwards, the vehicle is actually accelerated forward as the body of the occupant moves backward, thus forcing him or her into the seat. As the mouth is thrown open, producing TMJ injury, the head either hits the head rest or extends over the headrest
Common complaints following a CAD or Whiplash injury may include TMJ symptoms of joint pain, limited opening of the mouth, change in bite, TMJ noises and face pain |
