Abstract of the week
Bone anchored intraoral device for transmandibular distraction
M. Y. Mommaerts
p 8-12, Volume 39, Number 1, February 2001
Abstract
The Transmandibular Distractor (TMD) is an intraoral expansion device
for symphyseal widening by callus distraction. Its advantages include
limited surgical exposure, skeletal anchorage, and expansion along
the arch segment together with proportional and differential widening
in the frontal plane.

"I would start Fluoride varnish as soon as possible (Duraphat) on the
high risk kids. It's real easy and you don't need a dry field so it
will work well on semi-errupted teeth."
---------------------------------------------------
"The fluoride varnish is great for your perio patients too. We apply
it to furcation and iffy looking Class V areas. It's good for
treating dentin sensitivity too"
--------------------------------------------------
"I do have a concern about a health matter. Since September of last
year I have been not well on and off continuously until present. I
was told I had walking pneumonia in sept. but since then have had
same syptoms. They are voice horseness or lost voice completly,
tightness in middle of chest, extreme tiredness, lathargy, dizziness,
sometimes dry cough but at times with flem, lung tenderness and
tenderness to breath. Now the only thing that I can think of that is
different in all of my daily environments is the fact that I have
been using the prophy jet on most patients daily since last
summer.......has anyone else encountered any respiratory problems
when using the prophy jet???? all the physicians I have seen seem to
be baffled and just send me for breathing/lung tests.....I have for
the past week stopped using the p. jet to see if there will be any
change..."
-----------------------------------------------------
The 8-12 yr olds are our target. By the time they are teens they
have already lost both lower first molars and usuallt have had severe
pregnancy gingivitis. Large carious lesions and frank perio disease.
------------------------------------------------------
I would start targeting these kids at 51/2. As soon as the 1st molars
begin to errupt is when prevention starts for permanent dentition.
Those bombed out teeth started decaying as soon as they began to
errupt. The damage occurs between the age od 5/12 to seven while the
teeth are errupting and before they occlude with the teeth in the
opposing arch. That's when the bacteria and food stay together to
produce the acids in the occlusal grooves without the cleansing
effect of mastication. Your most effective prevention will occur
between the beggining of erruption and when the max and mand. teeth
occlude. This is when the teeth are most susceptible because of the
lack of occlusion and incomplete maturation of enamel.
I would explain some of this to the interested parent of the 5/12 to
6 year old. Show the parent how to brush those semi errupted 1st.
molars. Not just to try to remove bacterial plaque from the grooves
but to be applying the fluoride that's in the toothpaste. The more
times per day the better.
Next comes some kind of risk assesment to help decide how much the
kid actually needs. I assume you have a larger percentage of high
caries risk children than is typical. Risk factors, like degree of
previous caries activity on the deciduous teeth, socioconomic
factors, home care etc. (another whole section) must be considered
for optimum success. One size will not fit all here.
I would start Fluoride varnish as soon as possible (Duraphat) on the
high risk kids. It's real easy and you don't need a dry field so it
will work well on semi-errupted teeth.
Whatever else Dottie does, I would suggest she run the tip of the
small ultrasonic insert into the occlusal grooves of those semi
errupted occlusal surfaces. If the ultrasonic is spitting out CHX
instead of water all the better, when you're thinking about the
grooves in the picture I'll paste below. Some grooves are shaped so
that nothing else can get in except soft plaque deposits and
bacteria . Not a toothbrush bristle, not an explorer, nothing. Just
soft food and bacteria being held in close proximity manufacturing
the acid to start demineralization.
If the parent doesn't cooperate with the cleaning, bring the kid in
more often for a quick ultrasonic debridement of the grooves. It's
quick easy and cost effective. Also the high risk kid can quickly
have the fluoride varnish painted on more often while he's there. I
know this is hard for you Pontic because you say if they are too lazy
to brush and floss as told, the hell with them. But when you
understand that a kid can brush until he's raw and still not be able
to fit the the brush bristles into those grooves, you/we will begin
to resist "blaming the victim"
Here's a magnified photograph of the kind of occlusal groove I'm
speaking of , with a single toothbrush bristle. They're not all like
this, but this isn't a rarity either:
Everyone should save this picture to show parents who want to know
why sealants are suggested. I like the kind of patient education
that shows people what a hygienist can do for them.
No wonder the occlusal grooves are responsible for at least 75% of
all new caries.
I don't believe in routine sealants for everyone and every tooth, but
I sure want to have some around the office for situations like this.
I do want to say this is the most important part of caries
prevention; the treatment and instructions that are provided in those
critical ages where the molars are semi-errupted. The ages of 51/2
to 7 and then again from 111/2 to thirteen during the semi erruptive
stage of the 2nd molar. On average girls teeth errupt 6 months to a
year earlier than boys.
Every time you guys see one of those bombed out molars, try to
imagine what might have been if you got that kid and family
interested in prevention at 51/2 years of age when the tooth started
poking through the gum.
What I've said here was the back bone of a project in Varmland
Sweeden whereby the hygienists and their assistants were used in a
needs related program in a county where caries prevalence was among
the highest in the world. From 1979 to 1991 this needs-related
caries prevention program was introduced to all 3 to 19 year old
children in the County through the schools I believe. Caries
prevalence decreased from 6.5 to 1.0 DFS for 12 year old children,
the lowest in Sweeden where before it was the highest in Sweeden.
The percentage of caries free 3 year old children increased from 51%
to 94%. (the program started with expectant mothers). The program was
very cost effective as shown by the fact that in 1990 the mean
annual treatment time was the lower than all the other countys in
Sweeden.
Articicial water fluoridation is not permited in Sweeden and
naturally fluoridated water (>0.7mg F/L was available to less than 2%
of the residents of that county.
The higher the caries incidence, the more effective each preventive
measure that is introduced. That is why I think your office can be a
real demonstration project if you have any way to keep track of your
results.
According to the description of your practice, no matter how
successful the prevention program is, you will have plenty of
dentistry to keep you busy for a lifetime.
I think you wil be successful at enlisting parents to cooperate. No
matter what the economic conditions are, parents generally are
similar in wanting to keep their children free of the misery and
expense of dental diseases they had when they, the parents were
growing up. They just need to be convinced what is possible with our
current state of knowlege.
I know this isn't perio, but I hope it's of interest to enough
therapists that are looking for the sense of aceivement and
accomplishment that this type of work can bring. "
