Core Beam Computed Tomograpghy (CBCT) in Dentistry

19th October 2020 | Training

Cone beam computed tomography (CBCT) is a medical imaging technique where multiple X-ray images are taken and then combined to form a 3D representation of the target.

CBCT has become increasingly important in the treatment, planning and diagnosis especially in implant dentistry. During dental/orthodontic imaging, the CBCT scanner rotates around the patient’s head, obtaining up to 600 distinct images.  The scanning software collects the data and reconstructs it, producing something that can then be manipulated and visualized with specialized software.

It is not used routinely, because the radiation exposure from this scanner is significantly more than regular dental x-rays.

CBCT provides detailed images of the bone and is performed to evaluate diseases of the jaw, dentition, bony structures of the face, nasal cavity and sinuses. It does not provide the full diagnostic information available with conventional CT.  It helps in evaluation of soft tissue structures such as muscles, lymph nodes, glands and nerves. However, CBCT has the advantage of lower radiation exposure compared to conventional CT.

Benefits

  • The focused x-ray beam reduces scatter radiation, resulting in better image quality.
  • A single scan produces a wide variety of views and angles that can be manipulated to provide a more complete evaluation.
  • CBCT scans provide more information that conventional dental x-ray, allowing for more precise treatment planning.
  • CT scanning is painless, non-invasive and accurate.
  • A major advantage of CT is its ability to image bone and soft tissue at the same time.
  • No radiation remains in a patient’s body after a CT examination.
  • X-rays used in CT scans should have no immediate side effects.

We offer an online CBCT course, for operators of CBCT in Dentist practices.  It is for dentists and dental nurses who refer and operate but do not report on CBCT images.  It follows the HPA-CRCE-010 guidelines To find out more about CBCT, please contact Dental Training on 0118 9261533

Starting your morning the right way

9th March 2020 | Training

Alarm goes off at 06:25am. Each weekday morning, I somehow drag myself out of bed and dress for gym. I think the average person most likely wakes around this time to prepare for work. I’m not sure why I have difficulties in waking at this unsightly time. It must be the thought of the instructor causing my body pain. But I’m up and my day has begun. HIIT class 06:45am. From this point onward, my day gets easier! I have ‘rolled’ to the gym (luckily for me it is less than a...
