NTI causing anterior open bite
John & Ninetta
Wondering what is the frequency of this happening to the pros on this
newsgroup?

An NTI does not cause an open bite. It takes the teeth out
of the occlusal pattern long enough for the condyles to
seat where they belong. Not where the 'occlusion' tells them
to be.
Even with that said, I have had no significant changes with
many years of use in my practice.

I understand the etiology, but the esthetic result is an open bite. In your
case, my guess is that you have not had to do an occlusal equilibration as a
result of an open bite?

>0% for me.
I had one patient who wound up getting ortho as a result.

issue of condylar re-positioning not tooth movement.

Agreed. The reason for the post was that I have 2 patients return in the
past few weeks with an open bite. In each case, it was only a millimeter or
two, but they could no longer incise as they could before. This was not
acceptable to each patient.

few weeks of each other. In both of those cases, neither patient was in
active discomfort.....you could clearly see the patients were
grinders/clenchers (one had an existing flat plan guard that was 10 years
old and just wanted a new one). Since the condyles will go back to their
accomodating position, their bite will go back to what it was before the NTI
in time. I'll just make them a flat plane when that happens.
Even if they signed the consent for and it does happen, sure they are
prepared for it, but I think it depends how bad the patient's symptoms were
before the guard. If they did have jaw pain before hand but not anymore
with the NTI, then that patient more likely will live with the open bite as
its better off in the long run for them. However, if no symptoms and you
are using the NTI instead as more of a protective tooth appliance, then
you're more likely in the situation that the open bite will not be
acceptable to the patient. In the latter cases, you still want something in
between the teeth, so its just more predictable to make a flat plane guard
(with all its shortcomings) once things have settled, rather than doing
equilibration.
Thanks for the input.

If you take impressions and mount the models in the 'new' occlusal
pattern, you will be able to see how much equilibration is actually
needed to 'correct' the open bite.
This can be very little, or more than you would consider.
Doesn't hurt to check it out before giving up.
JMO,
