[A new modality for dentomaxillofacial imaging: cone beam CT].
Cone beam CT is an imaging technique used worldwide. It is a reliable and credible alternative to CT scan for dentomaxillofacial imaging. Radiation exposure may vary from one machine to another, but it remains definitely lower than CT dose levels. This technique is compatible with dental implant software. The major diagnostic advantage is the exquisite spatial resolution. The main pitfall is the poor contrast of face and neck soft tissues, due to a lower density resolution compared to CT scan.
