[Oradlist] Guidelines for CT/CBCT

Another voice from Europe:
it would be unfortunate if new guidelines are too bombastic on demands for
CBCT before any implant placement. Following the implant litterature, we are
aware of the trend to install an implant immediately after extracting the
tooth - or if the tooth had periapical infection - a few weeks after. This
may become the standard of care at least in some regions of the jaws. In
these cases the bone is certainly available and no cross-sectional imaging
In my university the students are doing implant installation as part of
their curriculum with the aid from the surgeons, and we do no
cross-sectional imaging in connection with this. If in a few cases the
surgeon lacks bone when opening up, they have ways to take care of this.
Maybe the question should be more about who is installing implants ...
all the best

> I suspect that is a fairly common European view.
