Hi Jan -
I love your analogy ... one which I also use in my presentations with
regards to building a house. I have also enjoyed my trips to Leuven, and the
wonderful Stella beer. However, perhaps we can take the analogy a bit
further. If it were a totally new house, on a vacant lot of land, where would
you want to build your house and how would you go about it?
Would you look at a piece of land, which might have a bunch of trees on it,
and have an architect draw up some plans without doing some type of survey
regarding the geography/topography in the area? Where is the water table
located? Is this a flood zone? Are there a lot of boulders in the soil
which might require costly excavation? Come up to the East coast here, and
boulders are a common problem... can add many thousands to have them
dynamited out of the ground.
So before building your dream house on a vacant piece of land, it might be
wise to get a survey of the "foundation"... because even with wonderful
architectural plans, if the foundation is faulty, the building can come down,
or tilt like the Leaning Tower of Pisa, due to the lack of proper support,
or if excavation is required, the fee goes up dramatically.
We can all make comparisons to real life - the bottom line should be that
clinicians should understand the underlying anatomy, the thickness of the
cortical plates, the quality of the bone, and the nearby vital structures
prior to exploratory "drilling..." required to place an implant.
In my humble opinion, CT and CBCT empowers clinicians with this 3-D vision,
and an understanding of the "foundation" in which to place the implants,
which will be support for the new "house..."
Your analogies to the different builders apply very well. Thanks for
taking time to chime in on what has become an interesting debate.
Regards to all -

This is actually my first post. I have been following this list since I
graduated from the University of Leuven with a Masters Degree in Biomedical
Sciences in 2005. I wrote my thesis on CBCT imaging with the kind help of
Prof. Reinhilde Jacobs, head of oral imaging.
There is an analogy that I frequently use to summarise these sort of
3D imaging can be compared with an architect drawing up the plans of your
The surgeon is the contractor or builder that will execute these plans.
The more precise your architect is in drawing up those plans (spot on
millimeter measurements, perfect foundations, accurate stability calculations),
the better ANY contractor can build this house.
A very experienced builder will benefit due to cost-efficiency (no
rebuilding walls when they come down halfway through the build due to bad
planning), speed (no surprises) and longterm customer satisfaction (the house is
still standing after a big storm).
A less experienced builder will have the same benefits and added
confidence in what he is doing because he can rely on the architect more.
Any builder can make mistakes, that's just human, regardless of how good
the architect has done his work. (frequency of these mistakes goes down with
more and more experience under the belt, or I would hope so :-)
Any builder "could" get the job done with exactly the same end-result,
even with plans that weren't that precise (panoramic or intra-oral imaging).
My two cents:
Can any surgeon benefit from CBCT? yes
Can any patient benefit from CBCT? yes
Can any surgeon achieve the same endresult without CBCT? yes
Does every surgeon NEED to take a CBCT before every implantcase? no
Would you personally get a detailed CBCT before getting implants (if the
cost of the scan was not a factor)?
