What is CBCT?
CBCT stands for Cone Beam Computed Tomography, a technology for oral radiographic imaging developed to have high resolution and can also display results in 3D, showing oral and dental structures more clearly. This helps improve diagnosis and treatment planning in dentistry, leading to more accurate results and better outcomes for patients.
What are the benefits of Cone Beam CT Scan?
CBCT is a high-resolution X-ray technology that can
- See all around the teeth from every side: including shape, height, width, thickness of the bone, surrounding sinuses, and jawbone
- Help plan wisdom tooth treatment: it can check the position of the wisdom tooth and whether it is close to the dental nerve for more precise surgical planning
- Assess bone in the area where implants are needed: to check if there is enough bone for implant placement and to see the implant placement path that avoids damaging other organs such as dental nerves and sinus cavities
- Help plan periodontal disease treatment in cases requiring root planing or surgery
- Help plan root canal treatment by showing whether the root canal is truly narrow, where the narrowing is, and its severity, including apical surgery
- Assist in planning treatment for temporomandibular joint disorders (TMJ)
- Help plan orthodontic treatment more accurately and achieve faster results
What is the procedure for a Cone Beam CT Scan?
The procedure for dental X-ray using Cone Beam CT Scan differs from 2D dental X-rays or traditional X-rays in that the images are clearer and more detailed. The patient only needs to sit still as instructed by the staff. The staff will put on a lead apron and a head strap, then adjust the head position with a chin rest before starting the scan. The Cone Beam machine will then rotate around the head for 20-30 seconds, and the procedure is complete.
What should you know before undergoing a Cone Beam CT Scan?
- Patients should avoid wearing any kind of jewelry
- Patients should be able to remain still for the required duration
- If pregnancy is suspected, inform the staff before the scan
CBCT is a tool that helps dentists plan treatments more easily and accurately, reducing side effects that may occur from treatment. Importantly, it is easy to perform and does not require placing any devices inside the mouth that may cause discomfort. For those interested in undergoing a CBCT scan, you can make an appointment for consultation at the Dental Center, Phyathai 3 Hospital every day
