Dear Dr. Ganz: A number of CBCT related position papers are in process by the American Academy of Oral and Maxillofacial Radiology.... as applicable in conjunction with other groups in the USA (e.g. American Association of Orthodontists, American Association of Endodontists...). We expect these new position papers and updates to be available from the Fall of 2010. The AAOMR is on record as recommending the use of cross-sectional imaging for dental implant placement planning, though the existing guidelines precede CBCT. Though I cannot state what the final product of the update on implant imaging might conclude, it is very likely that CBCT will be recommended for most, if not all, dental implant planning procedures. The age group for most dental ,implant placement cases, unlike orthodontic patients, is less susceptible to ill effects of radiation in the majority of cases. Further, without 3D imaging it is not possible to be certain of the anatomic variations possible that can impact on bone availability, or on the need to supplement bone by grafting when sufficient bone is not present where biomechanics indicate that an implant should be placed. My personal inclination is towards CBCT being the standard of care for placement of all endosseous implants used to replace missing teeth.

Dear Dr, Ganz,
you can find European (provisional) guidelines on CBCT use, including implants, on the SEDENTEXCT website:
This also gives reference to European Association of Osseointegration Guidelines (Harris et al 2002).
There are U.S. guidelines, but I expect that one of my U.S. colleagues will fill you in on those, as I believe they are working on their own guideline document.
The European Assoc. of Osseointegration guidelines (Harris et al) are out of date, as they predate the ready availability of CBCT, and need revision badly. Our recent SEDENTEXCT guidelines were rather cautious about the use of cross-sectional imaging, being based upon the CBCT evidence available (we did not review CT material).
I feel (as a radiologist) that if a surgeon judges that a cross-sectional image is needed for implants then I can't imagine a situation where I would say no to the request. On the other hand, if a surgeon feels that he/she does not need cross-sectional imaging, I would not "push" CT/CBCT. I suspect that is a fairly common European view.
I hope that gives a European perspective for you. As I said, your US colleagues will no doubt fill you in on their views.
Good luck with your task force work.
