Nightguard to Prevent Supereruption?

Since I recently lost a molar, I've been investigating supereruption
and nightguards. I'm hearing contradictory views on the topic.
Some say from personal experience... yes, a nightguard will prevent
supereruption... others say NO, impossible, it can not be
done unless a person wears the nightguard 24 hours/day(!)

Anyone familiar with this? Any nightguard ideas from persons
experienced in wearing or working with them?
What kind of nightguard will work? Any type?
Is a nightguard an effective way to prevent supereruption
of a molar?

Thank you.

Good question, Minerva. First, let me state that I am making an educated guess
here. In my opinion, I would tend to agree with those who have said that a
night guard will NOT prevent supraeruption unless you wear it 24 hours a day.
Also, I believe that the supraeruption would be significantly slowed if you
were to wear a hard acrylic nightguard. However, even the hard night guards
wear, and as it wore away, the tooth would have room to supraerupt. You
probably wouldn't even notice it happening, as it occurs very, very slowly. As
stated above, this is just my humble opinion. Others may disagree with me, but
that's what Usenet is all about !!!

Good luck,

Which molar? (how many teeth from the front?)
Why not just replace the tooth?

If the tooth supererupted every day slightly (as it might) over 16 hours
period, it would return in an otherwise healthy dentition with the night guard
wear for 1/3 of the day. This is the basic premise of wearing an orthodontic
retainer at night. Therefore in all likelihood consistent regular wear of a
nightguard at bedtime would most likely prevent unchecked supereruption.

a rigid hard plastic perfectly fitted one that may need to be adjusted a

Any type? Tanner type with anterior disclusion.

Absolutely. The research show that if the nightguard is worn at night the
little bit (and I emphasize a little bit in one days time) of eruption will
be resolve when you put the guard back on at night.
Actually, there are easier ways that cost about the same as the splint such
as a "valplast" partial or others. Ask Steve Mancuso, he has an intrigueing
compromise solution to a regular bridge.
good luck!

Frank,

We could easily place a Monodont in place of a missing molar for little more
than the cost of laboratory fabricated splint. It would hold the teeth in
position, provide function and esthetics and last a good 4-5 years. If the
missing tooth has no distal agonist, then the Monodont will not work.

Hi there,

I guess you want a splint instead of a bridge due to financial


reasons. If so, why not try an etched metal splint to prevent
the supereruption of the unopposed teeth?

Or, even better, an EastFlex bridge.

Supraeruption may not be a problem if the tooth in question is able to
contact a tooth in the opposite arch when your teeth meet.

True. And the contact doesn't even have to be great, the slightest
contact with something will prevent supereruption. A small etched
metal splint in the enamel on the premolar extending to the molar
will also do just fine (as long as it stays there), see picture below.

I don't know if I have a distal agonist or not...
The tooth that is missing is #18. All the other teeth are intact,
except wisdom teeth which were all four removed many years ago.
There is no tooth in back of the space where 18 was.
Is a Monodont possible in this situation?

Good point, Stan. As an afterthought (I was thinking about this as I drove
home last night), I thought that perhaps a night guard WOULD "do the trick"
because our teeth are normally not in occlusal contact except during
mastication and swallowing. Of course, parafunctional habits should be taken
into consideration, also, but if we all go around without our teeth in occlusal
contact for the great majority of the day, why don't they all supraerupt ?
Just an afterthought. Again, I must state that I am theorizing here, as I have
never attempted actual treatment of this type.

Now that you are informed ( a very important tool), your suggestion is perhaps
the wisest.

There is no tooth in back of the space where 18 was.
Is a Monodont possible in this situation?

Thank you for the illustration.
In my case, there is no vertical stop, not even a corner, and there is
no tooth behind the missing tooth (#18).
That's why I'm looking at the possible ways to stop the tooth.
I wish there was a stop for the tooth, but there is not.
So I'll have to have one manufactured, asap.

Hey Maris,

Is it time to start a new thread describing your little gem again?

Frank, we can discuss the Monodont personally if you like. I am trying to
work up a good demonstration case right now. I have one person who could
use one on each side to replace upper first premolars. I am going to offer
them at half price in exchange for liberal release signatures on sharing the
images I make of them. If this works out, I'll photograph each step of the
process.

Minerva,

If your missing tooth is the last tooth in the back with no tooth behind it,
your best choice for replacement may only be an implant. A MonoDont
requires a tooth in front of and behind the missing tooth's space.
