What Is Cone Beam CT Scan And How Does It Work

What Is A Cone Beam CT Scan?

A Cone Beam CT scan is an advanced imaging technique used in dentistry and maxillofacial surgery. It provides a detailed three-dimensional view of the teeth, jaw, and surrounding structures, unlike traditional X-rays. It offers high-resolution and distortion-free images, allowing healthcare professionals to diagnose and evaluate dental abnormalities more accurately.

How Does Cone Beam CT Work?

The Cone Beam CT scan operates using a unique mechanism that sets it apart from traditional X-ray systems. At the heart of its operation is a cone-shaped X-ray beam, hence the name “Cone Beam”. This beam rotates 360 degrees around the patient’s head, capturing multiple images in a single rotation.

As the patient sits still, the X-ray source and detector move in unison around the patient. The X-ray beam projects a series of images onto the detector with each rotation, capturing a different perspective of the patient’s anatomy each time. These images are known as “basis images”.

The basis images are then digitally processed and compiled by a sophisticated computer algorithm to create a single, three-dimensional representation of the patient’s oral and maxillofacial region. This 3D image can be viewed and manipulated on a computer screen, allowing for a comprehensive evaluation of the patient’s dental structures, soft tissues, nerve paths, and bone.

This entire process happens swiftly, often within a matter of seconds, making the Cone Beam CT scan a quick, efficient, and highly effective tool for diagnostic imaging in dentistry and maxillofacial surgery.

What Are The Benefits Of A Cone Beam CT Scan?

Cone Beam CT scans have revolutionised the field of dental and maxillofacial imaging. Here are some of the key benefits:

  • Detailed 3D Imaging: Unlike traditional 2D X-rays, Cone Beam CT scans provide three-dimensional images. This allows for a more comprehensive view of the teeth, jaw, and surrounding structures, facilitating accurate diagnosis and effective treatment planning.
  • High-Resolution Images: Cone Beam CT scans offer high-resolution, distortion-free images. This level of detail enables doctors to detect and evaluate the extent of dental abnormalities with greater precision.
  • Non-Invasive and Painless: The procedure for a Cone Beam CT scan is non-invasive and painless, making it a comfortable experience for patients.
  • Quick Procedure: The entire scanning process takes less than a minute, making it a quick and convenient diagnostic tool.
  • Lower Radiation Dose: Cone Beam CT scans expose patients to a lower dose of radiation compared to conventional CT scans, making them a safer choice without compromising on the quality of the images obtained.
  • Versatile Applications: Cone Beam CT scans are used in various fields of dentistry, including orthodontics, implantology, endodontics, and oral surgery. They are also used for the evaluation of the temporomandibular joint, assessment of the jaw and face for surgery, and detection of jaw tumours.
  • Improved Patient Care: By providing a clear and detailed view of the patient’s anatomy, Cone Beam CT scans enable healthcare professionals to deliver more precise and effective treatment, leading to improved patient care and outcomes.

How Is The Procedure Performed?

The procedure for a Cone Beam CT scan is straightforward and painless. The patient is seated in the examination room, with their chin resting on a small support shelf for accurate positioning.

The scanner then moves around the patient’s head, capturing multiple images from various angles. These images are subsequently processed by a computer to generate a 3D image of the patient’s dental and maxillofacial region.

The entire process takes less than a minute, making it a quick and convenient diagnostic tool.

How Much Is A Cone Beam CT Scan Cost?

The cost of a Cone Beam CT scan in Australia varies, but it generally ranges from AUD $250 to AUD $350 per scan, depending on factors such as the location, the imaging centre, and additional services required.

Does Insurance Cover Cone Beam CT Scan?

Medical insurance coverage for Cone Beam’s CT scan was off the books for a while. But slowly with the wide acceptance of this procedure, insurance companies are falling in line by providing partial or full coverage. To be certain, you need to make inquiries.

Also, you can opt for a separate dental coverage specifically made for your Cone Beam CT scan. 

Note that this policy is not included because of the newness and uncertainty surrounding its emergence.

Is A CT Scan The Same As A Cone Beam?

Although they are quite similar, the traditional CT scan varies in specifications from the Cone Beam. Traditional CT scan involves 2D imaging, intrusive testing, and longer test hours. But the Cone Beam is simplified with faster scan time, a better quality of images, and an easier testing method. 

Adding to the bulk of differences between both, root canal and deep ailments specifically need the CBCT to delve deeper than the average CT scan. This is why it is acceptable if you place the CBCT as the best way to diagnose and treat dental issues.

How Long Does A Cone Beam CT Take?

The maximum Cone Beam scan time for a full mouth test is a minute and the shortest scan time is 20 seconds. In all, it is a really quick procedure.

How Do I Prepare For A CBCT Scan?

A Cone Beam scan does not require intensive preparation. When you get to the dentist’s, you will have to remove jewellery or any metal objects you have on, after which you can proceed. 

 How Much Radiation Is In A Cone Beam CT?

There is no static measure of radiation in a cone Beam CT scan. It depends on your size, the display quality, and your interest points. The amount is between 18-200úsv. Compared to other x-ray procedures, this is safer. Although the radiation rate most times seems so low, getting a Cone Beam CT scan too often may have adverse effects on your health. It is recommended to be done occasionally or only when needed to spot immediate discomfort.

Which Is Better, CT Or CBCT?

A CBCT is often recommended in cases involving the mouth’s bones and tissue. This can be termed as not easy to identify physical or underlying conditions. It’s a way to go beyond the surface, see the root cause of symptoms, and evaluate the effect of treatment methods. Whereas the CT will also give you dental care but not in clear details like its more advanced counterpart.

Does CBCT Scan Hurt?

Absolutely not. This scan is painless and fast. You’d barely feel anything while having one. And even after it is done, you can still expect to feel normal.

Why Do We Need CBCT?

There are numerous reasons why you shouldn’t toy with getting occasionally checked using CBCT. A CBCT will help you diagnose the exact problems you are facing and recuperation progress all in record time.

I was at a really low point in my life, had an accident 2 years ago which broke 3 of my teeth and a bridge in between my 2 front top teeth. From that moment I became extremely conscious of going out,socialising and found my self withdrawn and depressed as I didn't know what to do.Then a friend told me about My Implant Dentist. I plucked up the courage and went for my first consultation at Mindarie Quinns dental practice with Dr Zaheer who explained all my options and advised all on 4 top and bottom.Not only Dr Zaheer but all the staff and doctors at both Mindarie and South Perth were amazing and extremely professional and made the whole process seemless.Having the treatment has given me back confidence and enabled me to socalise and do things with my family and friends that I couldn't do before.I would like to thank Dr Zaheer and all the team at My Implant Dentist for everything they have done for me and recommended them to everyone I speak to.I just can't stop smiling!!!

From the moment I walked in the door My Implant dentist were very caring and professional. As a dental nurse myself I knew I would be a very hard case as other specialists said they could not help me. After my first consultation with Dr Kent he was confident that he could help me and I was provided with a clear plan for my top and bottom all on four procedure. My new teeth are perfect and so natural looking. He has made the impossible possible for me. I can smile and eat the foods I love again and this has changed my life. Thank you so much to all staff and especially Dr Kent Tan who I can say is the best implant dentist in Perth.

I picked up”Moorooka Dental Care” contact details from the web. I rang for a few questions and the happy voice of Frances had calmed my anxiety down quickly!Dr Kadwa greeted me from the front bench, took me in for the X-ray, dental assessment, carefully explaining the procedure, answered my questions and quoted for the works. He offered to breakdown work items to suit with my needs. The quote was surprisingly very compatible with my previous quote from overseas. (I know I am going to have my dental treatment in the safe zone, most medical advances in Australia).The implant work went smoothly, so smooth that the team had to remind me “Done!”, well beyond my imagination.When he saw me off with the aftercare instructions, I could feel his professional manners with caring characters. I know he has done a few thousand implants but I still received the care of his first. Thanks Zaheer!I requested X-ray images, Fatimatu responded promptly with friendly chatting.I also would like to thank Dr Linh Trần who was in the operation team at the treatment and follow up cares.

Moorooka dental have been a pleasure to deal with. I did a bit of research into dental implants and most companies had hidden fees. I booked a consult and was contacted within a few hrs to get me in and get the ball rolling. I choose to go with he implants using my super. They helped me to do all the paperwork to release the money. Definitely a good dental clinic.
