Anterior Bite Plane ¹ Anterior Point Stop
Below is a series of messages from the parent of an 11 year chronic headache sufferer.  This is intended to demonstrate the attention to detail that can mean the difference between success or failure of treatment.

Dr.  Boyd,
     I was wondering if you could help me.  I have an 11 year old child who is suffering from headaches 24 hours a day, 7 days a week, for 8 weeks.  He had an MRI which ruled out any medical problem.  I have been to an oral surgeon who said that he clenches his teeth.  He fitted him with the traditional splint.  After 5 weeks there has been no improvement (it may have even gotten worse).  A neurologist that I took him to said that the headache were not TMJ related.  He put him on Depakote.  No relief after 2 weeks.  At this point, I don't know how to proceed.  Are the headaches related to clenching or not?
     There is tenderness in the temporalis muscles and his jaw hurts upon waking in the morning the jaw pain disappears during the day).  On the other handthe headaches are not typical TMJ type headaches.  It is a
throbbing pain across the forehead plus a shooting pain every thirty seconds.

Elliot,
The oral surgeon has the correct diagnosis, but wrong treatment.  Clenching is not reduced with the mouthpiece your child received, but in  many cases, is increased.  http://www.headacheprevention.com/pages/whatisit.html
Either have the O.S. make an NTI, or check this list for one near you: http://www.headacheprevention.com/pages/finddds.htm

My wife this afternoon took my son to a dentist who does NTI.  The dentist said my son has classic MFP.  However he cannot do NTI because his bite is too deep.  So I am back to square one.  I cannot even begin to describe my son's suffering.
 Thank you,
Elliot W.

Dr. Boyd,
On Sunday I spoke to the dentist again.  Apparently there was some confusion.  He told me that he didn't say that he can't do it but that he wanted my son's orthodontist to do it.  I brought my son to him this morning and he took an impression.  My son's problem is an overbite; his top front teeth go to far over his bottom front teeth to use the prefab NTI.  His technique in this situation is to create for the patient a standard type acrylic bi-plate that attaches to the palate and is held in place by a wire around the teeth and the DE is attached to the bi-plate, preventing contact between the molars and the canines.

Perfect!

Dr. Boyd,
I am sorry to bother you again.  I'm the one with 11 year old with  chronic 24/7 headaches (10 weeks).
My son has received his custom appliance.  He has worn it for 6 nights (and most of the day).  There has been no improvement at all.  He has the headaches with the same intensity and his jaw still bothers him.   My wife spoke to the dentist and he said he would wait another week. If there is no improvement, he would open the bite a little more (he said he kept it at minimum for fear of worsening his overbite).  Is it possible  for the healing process to take this long to begin taking effect ?

Any chance you can provide a picture of the device while in place?  (more than one view would be good).
As for vertical dimension, sometimes nothing happens until it is opened up a bit more.

Elliot,
     It sure looks as though this device didn't accomplish what it was intended to do, which is prevent canine contact.   (those were great pictures, BTW.)
Review this page to see the potential clenching difference between a bite plane (what your son has) and a bit stop (what we're trying to create):  http://www.DrJimBoyd.com/CanineSignificance.html
I've altered your photos to demonstrate what modification could be made to your son's current device.
See if the orthodontist, or your dentist can add a "Discluding Element" to the bite plane, or even easier, reduce the acrylic at the far ends of the bite plane so that the canines can't touch it.
Let me know how it goes.
