For dental implants evaluations, do you really need ct scan. any concerns from using cat scan kodak 9500 cone beam scanner. how much radiations?

Depends: Many surgeons work from panoramic and PA single images with great success, precision and safety. However, for more complex applications around the sinus and inferior alveolar nerve areas, the 3D scan is the standard for safety and accuracy. Even then, we see differences once we clinically visualize the bone. Radiation exposure is less than you might think as it is quickly completed. Good Luck.

It is essential: Today, the most accurate technique for preoperative evaluation of dental implantation is dental CB-CT.

Yes: It is the best course of action, the more accurate the pre operative preparation, the better the outcome. Today CT Scan represent almost the same amount of the old panoramic Rx.

Amount of radiation is less that a couple of days of normal background radiation, in other words very low. In a risk/reward situation, the risk is infinitesimally small, the reward in information gained, huge.
