In dentistry, 3-D Head CAT Scan or Dental Cone Beam CT generates accurate, focused, and quality 3-D images of dental structures, soft tissues, nerve paths and bone in the cranio-facial region. Its use is for treatment planning orthodontic cases, impacted teeth, TMJ diagnosis, dental implant placement, evaluation of jawbone, sinuses, nerve canals and nasal cavity, locating origin of pain or pathology, and reconstructive surgery.
