Cone Beam Computed Tomography (CBCT) is an advanced imaging technology revolutionizing dental care. Unlike traditional dental X-rays, CBCT delivers detailed three-dimensional (3D) images of teeth, soft tissues, bones, and nerves, enabling more accurate diagnoses and treatment planning.
Since its introduction in the late 1990s, CBCT has gained widespread use in dentistry due to its ability to provide precise imaging with lower radiation exposure. It is now a cornerstone in various dental specialties, including endodontics, implantology, orthodontics, and oral surgery, where precision is critical to achieving optimal outcomes.
This comprehensive guide explores the technology, benefits, and applications of CBCT, providing insights for both patients and dental professionals. Learn how CBCT is shaping modern dental care and why it might be the ideal solution for your imaging needs.
Here at Enhance Dental Centre, we employ this technology in-house on a daily basis—a capability that many other practices typically outsource to costly imaging centres. We are your comprehensive provider for all your dental needs.

How does CBCT technology work?
Cone Beam Computed Tomography (CBCT) uses a cone-shaped X-ray beam that rotates around the patient’s head, capturing multiple images from various angles. Unlike traditional dental X-rays that produce flat 2D images, CBCT combines these images to create a highly detailed 3D view of the mouth and face.
The Cone-Shaped X-Ray Beam
CBCT employs a cone-shaped X-ray beam that covers a larger area in a single rotation. This minimizes the number of scans required compared to traditional methods, reducing radiation exposure while maintaining detailed imaging.
3D Image Reconstruction Process
CBCT scans generate 3D models through a multi-step process:
- Image Acquisition: The X-ray source and detector rotate 360 degrees around the patient, capturing numerous 2D images.
- Data Processing: Advanced software converts these images into a comprehensive 3D model, providing axial, coronal, and sagittal views.
- Visualization: Dental professionals can examine the 3D images from any angle, zoom in on specific areas, and assess details of teeth, nerves, soft tissues, and bone.
This cutting-edge process enables precise diagnosis, treatment planning, and procedure execution, revolutionizing dental care.
How does CBCT differ from regular dental X-rays?
CBCT stands out from traditional dental imaging methods, such as 2D X-rays and conventional CT scans, by offering detailed 3D images with lower radiation exposure.
Traditional Dental X-Rays
Traditional dental X-rays have long been used to diagnose cavities, assess bone loss, and evaluate oral health. However, they provide flat 2D images, which can miss complex issues hidden behind overlapping structures.
- Limitations: Flat images may not reveal detailed or hidden dental structures.
- Radiation Exposure: Multiple X-rays may increase cumulative exposure, especially in old offices that still utilize manual film, those require a stronger radiation setting to provide a clear view.
- Use Case: Ideal for routine checkups and diagnosing surface-level problems, such as cavities.
Conventional CT Scans
Conventional CT scans produce 3D images of the body but are not tailored for dental needs. These scans emit higher radiation, take longer, and often include unnecessary areas outside the mouth.
- Limitations: Higher radiation exposure and lack of dental-specific focus.
- Soft Tissue Detail: Effective for medical diagnoses but less suited for dental imaging.
- Use Case: Best for full-body or medical imaging, not practical for specific dental procedures.
Advantages of CBCT
CBCT provides advanced dental imaging techniques for dental care, offering clear, 3D images of the mouth and face. It surpasses the precision of regular X-rays and CT scans, enabling more accurate diagnoses with reduced radiation exposure. This makes CBCT an essential tool for advanced dental treatments.
Accurate Diagnosis
CBCT provides detailed 3D images of teeth, jawbone, TMJ, and sinuses, identifying issues traditional X-rays might miss. It allows dental professionals to detect small fractures, infections, or impacted teeth with precision. This level of detail ensures accurate diagnoses and effective treatment planning.
Precise Treatment Planning
CBCT’s 3D imaging helps dentists plan complex procedures like implants, root canals, and jaw surgeries with accuracy. It allows assessment of bone density and nerve positioning, reducing risks. This precision leads to safer procedures and better treatment outcomes.
Reduced Radiation Exposure
CBCT offers high-quality imaging with significantly less radiation than conventional CT scans. Its focused imaging reduces unnecessary exposure while maintaining clarity. This balance ensures patient safety during both routine and advanced diagnostics.
Applications of CBCT in Dentistry
CBCT has revolutionized dental care by providing clear 3D images that enhance diagnosis and treatment planning across multiple dental specialties.
- Endodontics: CBCT reveals detailed root canal anatomy, enabling dentists to locate missed canals, fractures, or infections with precision. This ensures thorough and effective root canal treatments.
- Implantology: CBCT aids in planning and assessing implant placement by providing detailed views of bone density, nerve pathways, and sinus positioning. This minimizes complications and improves implant success rates.
- Orthodontics: CBCT delivers comprehensive views of tooth alignment, jaw relationships, and skeletal structures. These insights help orthodontists design accurate and efficient treatment plans.
- Oral Surgery: CBCT supports oral surgeons by offering detailed information on impacted teeth, jaw tumors, and fractures. It ensures precise surgical planning for better outcomes.
By offering tailored, high-resolution 3D images, CBCT empowers dental professionals to make confident, well-informed decisions, improving patient care significantly.
What to Expect Before, During and After the CBCT Procedure
Before the Scan: You don’t need special preparation, but remove metal items like glasses, dentures, earrings and remove any face piercings if possible to avoid interference. Inform your dentist if you are or might be pregnant.
During the Scan: You will sit on a chair or stand while the technician positions your head. Staying still is crucial for accuracy. The complete scan doesn’t take more than a few minutes.
After the Scan: The machine captures 150–200 high-resolution 2D images, combined into a 3D model. Your dentist reviews the results and recommends the next steps. You can resume normal activities immediately.
Safety Considerations and Risks
CBCT provides detailed imaging with safety in mind, using radiation levels higher than traditional X-rays but significantly lower than conventional CT scans.
- Radiation Exposure Levels
CBCT scans may emit more radiation than standard X-rays but far less than regular CT scans or old film traditional x-rays, making them a safer choice for dental diagnostics. - Safety Protocols
Clinics implement strict protocols, including the use of shields and targeted imaging, to minimize unnecessary radiation exposure. - Special Considerations
Pregnant patients, children, and high-risk individuals should consult their dentist to determine if CBCT is necessary or if alternative imaging options are available.
Cost of CBCT Scans
The cost of a Cone Beam Computed Tomography (CBCT) scan in Canada varies based on factors such as equipment, clinic location, and scan complexity. High-tech machines and specialized software can increase costs, while urban clinics may charge more due to higher operating expenses. Complex cases requiring additional analysis may also add to the price.
Generally, CBCT scans are more expensive than traditional dental X-rays but less costly and more targeted than conventional CT scans, making them an efficient choice for detailed dental imaging.
Cost Comparison Chart
| Imaging Method | Typical Cost Range (CAD) | Use Case | Radiation Exposure |
| Traditional X-Rays | $30–$100 Per Image | Routine Dental Checkups, Detecting Cavities | Lowest Radiation Exposure |
| CBCT Scan | $220–$400 Per Scan | Detailed Dental Imaging For Advanced Procedures | Moderate, Lower Than CT Scans |
| Conventional CT Scan | $375–$2,000 Per Scan | Medical Imaging Or Extensive Oral Issues | Higher Than CBCT And X-Rays |
Note: Prices are approximate and can vary based on location and specific clinic fees.
