Maybe you would like to start a thread on this topic which you've
brought to our attention.  It looks like it will soon get lost under the
current subject line.  

I replied to W_B's reply in the thread "The Connection between smd and
asj-d" with these two links:

http://sleepdisorders.about.com/cs/sleepdeprivation/a/oraldevices.htm

http://www.umm.edu/patiented/articles/what_dental_devices_used_treat_slee
p_apnea_000065_9.htm

This next link may shed more light on the issue of contraindications
which is more likely to point to your original concern about sleep apnea
devices and temporomandibular joint problems.

Interesting topic, SP!
