In the facebook TMJ/TMD Discussion Group discussion one person posts the above picture asking if that splint will help with her TMD. It opened up an interesting discussion out of which reveals most doctors don’t have clear explanation of what causes TMD?
John Mew states that all bite splints cause the face to lengthen.
I asked Mike Mew on this matter and he agrees, one of the reason being overtime the masseter muscle will become accustomed to being lengthened and this will surely cause an increase in vertical dimensions. To me this is symptom alleviation and not addressing the cause.
The cause of all these issues is Cranial Facial Dystrophy or Maxilla that has dropped down and back.
John Mew posted in the comment section and shares his ideas on this matter.
