Cone-beam computed tomography (CBCT)
Cone-beam computed tomography (CBCT) has revolutionized dental and maxillofacial imaging by enabling compact, affordable, 3D visualization with lower doses compared to medical CT. This review examines CBCT’s principles, clinical advantages, limitations, and its expanding role in modern dental care.
Advancements in cone-beam computed tomography have redefined radiographic practice in dentistry. CBCT delivers volumetric imaging using a cone-shaped X‑ray and a flat-panel detector, producing 3D scans that reveal internal structures with high fidelity.
Working Principles
- Rotational scanning around the patient’s head captures multiple angled X‑ray projections.
- Reconstructed into a voxel-based 3D volume, these data are easily navigable across all planes.
Applications
- Implantology: Critical for accurately mapping bone structure and vital anatomy pre-implant placement.
- Endodontics: Detects hidden root complexities, vertical fractures, and periapical issues more reliably than traditional radiographs.
- Orthodontics: Assists in assessing impacted or ectopic teeth and skeletal deviations.
- Surgical & Trauma Imaging: Offers detailed views of facial fractures, infections, and surgical planning.
Key Benefits
- Eliminates superimposition artifacts seen in 2D imaging modalities.
- Offers a safer imaging option due to lower radiation exposure compared to full CT.
- Space-efficient and cost-effective for dental clinics.
Digital Dentistry Means Smarter, Safer, and More Comfortable Care
- Radiation safety remains important—CBCT should be used judiciously.
- Artifacts from metal and limited soft tissue contrast can hinder diagnostics
- Interpreting CBCT accurately requires specific clinical training.
Future Directions
- Enhanced detector tech and AI-driven analytics will further elevate CBCT’s diagnostic power.
- Innovations towards ultra-low-dose CBCT systems aim to improve patient safety while maintaining image quality.

FAQs
01. What is CBCT and how is it different from a regular dental X-ray?
CBCT (Cone-Beam Computed Tomography) produces 3D images of the teeth, bone, and surrounding structures, offering far more detail than a traditional 2D dental X-ray. It helps dentists make more accurate diagnoses and treatment plans.
02. Is CBCT safe?
Yes. CBCT uses significantly less radiation than conventional medical CT scans. At Restore Dental Clinic in Gurgaon, we use low-dose CBCT systems that are safe for both adults and children when used appropriately.
03. What are the common reasons a dentist might recommend CBCT?
CBCT is often recommended for:
- Dental implant planning
- Root canal treatment (endodontics)
- Evaluation of jaw tumors or cysts
- Diagnosing impacted or missing teeth
- Orthodontic assessment
- TMJ analysis
04. How long does a CBCT scan take?
A typical CBCT scan takes less than a minute to complete, with the actual scanning time often under 20 seconds. The results are available almost immediately.
05. Do I need to prepare for a CBCT scan?
No special preparation is required. You may be asked to remove metal objects (like earrings or glasses) before the scan.
06. Will I feel anything during the scan?
No. CBCT is a non-invasive, painless procedure. You simply need to remain still for a few seconds while the scanner rotates around your head.
07. Can children undergo CBCT scans?
Yes, but only when necessary. At Restore Dental Clinic in Gurgaon, we follow strict guidelines to ensure radiation safety, especially for children. We use CBCT only when the diagnostic benefit outweighs any minimal radiation risk.
08. Is CBCT imaging covered by insurance?
In many cases, yes. However, coverage depends on your specific insurance provider and the reason for the scan. Our team can assist you in checking eligibility and submitting claims.
09. Who interprets the CBCT results?
The scan is interpreted by trained dental professionals or radiologists with expertise in CBCT imaging. At Restore Dental, our clinicians are certified to read and analyze CBCT scans accurately.
10. Why should I choose Restore Dental for CBCT imaging?
Restore Dental Clinic in Gurgaon combines expert clinical care with advanced digital tools like CBCT to deliver accurate diagnoses, safer procedures, and superior treatment outcomes. Our focus on patient comfort, precision, and innovation makes us a trusted name in modern dental care.
