    • temporomandibular disorder (TMD)
  23. what is it called when the head of the condyle moves too far anteriorly and gets stuck past the articular eminence?
  24. what is the treatment for subluxation
    relax the muscles with time or medication and carefully move the mandible downward and back
  25. what are 5 symptoms of TMD?
