12. Bruxing Without Muscles

• Grinding motion.

Purposes

  • Show the bruxing motion without any distracting muscles or disc.
  • Identify why bruxing leads to tooth sensitivity, wear and looseness.


Each animation includes supporting photos and is equipped with detailed clinical notes

Presenting

  • Move jaw from acquired bite position back to full seated, centric relation, position.
  • Explain that if the bite came together when the jaw was fully seated, then there would be no need to brux.
  • However, with a bite that is not in centric relation, bruxing can occur because the muscles are at war (shown in the next animation) and can't relax. When the muscles go to a relaxed position, a tooth is contacting and the unconscious brain will try to protect the tooth and the jaw moves forward into a muscle strained position; but the muscles want to relax, so the jaw is moved back. The forward and backward motion can continue for hours.
  • Click the Loop button down, then click the Play button to have the bruxing occur continually - just as it will when the client is asleep.
  • This is often why apparently sound restoration work can fail.
