3-D volume imaging for dentistry: a new dimension.
The use of computed tomography for dental imaging procedures has increased recently. Use of CT for even seemingly routine diagnosis and treatment procedures suggests that the desire for 3-D imaging is more than a current trend but rather a shift toward a future of dimensional volume imaging. Recognizing this shift, several imaging manufacturers recently have developed 3-D imaging devices specifically for dental purposes using cone-beam computerized tomography. This technology allows for 3-D imaging similar to CT, but at lower equipment cost, simpler image acquisition and lower patient radiation dose. Herein, an overview of these devices is provided such that potential users can be better informed about this emerging technology.
