Occasional palatal swelling: Resorption mapping

Subject: [roots] 1st cbCT case
Here's the first one we did with our new Kodak 9000. We installed on Thursday the 11th and it just so happened
that this patient walked in that morning. We offered her a free cbCT ( supervised by the Kodak rep) as a test case.
49 year old female in good health had a history of occasional palatal swelling at the gingival margin of the
maxillary left central incisor. She had previous Ortho treatment as you can tell by the blunting of the apices.
Although she was not in any acute discomfort, there was some doubt as to whether an exploratory Palatal flap was
worth the effort. I consulted with the Periodontists in the building ( who were kind enough to locate teh cbCT
in their office ) and they were also insterested to see what it would show.
The scan showed that the palatal ECIR was larger than we had anticipated and that it was not worth flapping
the case to try to determine the extent of the resorption. The patient was scheduled for implant treatment plan
to include extraction and replacement by my periodontist friend. The use of the cbCT had one added bonus -
by NOT flapping the palatal area in between the 2 centrals we preserve the papilla for optimal implnat aesthetics.
IN teh past, we may have done teh exploratory surgery and lost this important soft tissue aethetics. So, by
(normally) charging the patient a few hundred dollars for the scan we:
(1) get a much better assessment of the area
(2) avoid costly surgical procedures
(3) preserve important soft tissue anatomy in the aesthetic zone
(4) Steer the patient in teh direction of a treatment that has less guesswork, higher predictability and that
works....the first time.
Still working on getting report formats/images in teh proper places so please excuse the mish mash of images.
I can see me now ROUTINELY charging the patient another couple hundred bucks in the diagnosis/exam of retreatment
cases with LEOs. I will tell em that if tehy want me to dissassemble/reTx - I gotta know what I'm getting into....
THIS is the best way to know that.
The Kodak 9000 is one VERY cool machine. I can see me using more and more...even though I DON'T do implants

Awesome!! - Fred
Rob, I'm jealous, we don't have one of those yet, I still order CBCT take out burgers.
...very handy for resorption mapping - Terry
Rob,Will you really be able to see initial VRF or extension of Craks vs Split tooth even under cronws, with CBCT?
Will you be able to see 3 MM missed canal or other aberrant ones, with CBCT?
What about extensive decay under former-long bridges that are not evident under clinical or
convetional X-ray examination? You will be able to predict restorability of those teeth previous dissasembly, with CBCT?
If those are the cases, send cases as soon as you diagnose those ones please.
How much do you calculate you should charge for CBCT?
How much do you use to charge for dissasembly complex cases: crown, bu, posts, fractured files, ...?

Will you really be able to see inicial VRF or extension of Craks vs Split tooth

I'm not sure about that. We'll try a few test cases to see what happens. The crowns may cause some
beam scatter that may affect our ability to see that level of detail. Perhaps some of the others that
have cbCTs will be able to answer that question now.
Will you be able to see 3 MM missed canal or other aberrant ones, with CBCT?
I think that aberrant and missed canals should be visible with this technology. Since we know that
" you need pulp to form roots" - closely examining the cross sections of the root can often give us a
hint as to where these canals "should be".
What about extensive decay under former-long bridges that are not evident under clinical
or convetional X-ray examination? You will be able to predict restorability of those teeth previous dissasembly, with CBCT?
I don't think that the scans have that level of resolution ( yet). Again, you may get "hints" but they
do not yet replace conventional films for those applications, in my opinion.
If those are the cases, send cases as soon as you diagnose those ones please.
How much do you calculate you should charge for CBCT?
We will be having discussions with my cbCT buying partners on Friday. I think we will be charging the equivalent
of around $200 US for the cases I do. We will offer this service to other dentists in the city but WITHOUT
interpretation - dentists will have to read their own images.
How much do you use to charge for dissasembly complex cases: crown, bu, posts, fractured files, ...?
In the area where I live,we have a specific fee guide that most endodontists use. There are different fees for
many aspects of the case, crown removal, post removal, retreatment, number of canals etc - Rob
Rob is spot on. Vrf is identifiable, but if metal restorative is in the neighborhood, scatter can make it
impossible to find. Interesting cost point decision rob. I recently dropped our fee to 200 u.s. from 350,
more affordable to the patient and frankly we make it up in volume. We do not charge for followup scans or
post implant scans, just for diagnostics.
This is really cool to me that we now have world class practitioners using 3d imaging. I’ve been fighting
the fight for 5 years, usually getting dumb ass responses like “I’ve been working without it since wwII,
I don’t need it now,” etc. the more folks utilize the technology, the more uses, the more incentive to move
ahead with r and d on the part of the manufacturers, etc. damn, I wish I was 20 something again.
I’ll be retired or dead before we see all that technology is going to give us - gary
