Cone Beam CT (CBCT) 3D Imaging

What Is Cone Beam CT?

CBCT is a specialized X-ray technology that captures a cone-shaped beam of radiation in a single rotation around your head, producing hundreds of two-dimensional images that are reconstructed into a detailed 3D model. This model allows Dr. Brumbaugh to view cross-sections of your anatomy from any angle, measure bone dimensions precisely, and identify conditions invisible on traditional films.

Clinical Applications

CBCT imaging supports accurate diagnosis and treatment planning across multiple areas of dentistry:

• Dental implants: Measures bone height, width, and density at proposed implant sites; identifies nerve canals and sinus proximity to avoid complications
• Root canal therapy: Reveals extra canals, curved roots, and periapical infections that standard X-rays often miss, improving outcomes for endodontic treatment
• Oral surgery: Maps impacted teeth, cysts, and tumors in relation to critical structures before extractions
• TMJ evaluation: Visualizes joint anatomy to assess condylar changes, erosion, or other joint disorders
• Orthodontic assessment: Evaluates bone support, impacted teeth, and airway dimensions
• Fracture detection: Identifies vertical root fractures and jaw fractures undetectable on 2D images

CBCT vs. Traditional X-Rays

Traditional dental X-rays produce flat, two-dimensional images where structures overlap and important details can be hidden. CBCT eliminates this limitation by providing slice-by-slice views and full volumetric data. The result is earlier detection, more confident diagnoses, and treatment plans built on complete information rather than assumptions.

Low-Dose Radiation

Modern CBCT units deliver substantially less radiation than medical CT scanners, typically equivalent to just a few standard dental periapical X-rays. Dr. Brumbaugh prescribes CBCT imaging only when the diagnostic benefit clearly outweighs the minimal exposure, following established ALARA guidelines. The scan completes in under 20 seconds, further minimizing dose.

What to Expect

A CBCT scan is quick and comfortable:

1. You will be asked to remove jewelry, glasses, and any metal accessories near your head
2. You stand or sit while the C-arm of the scanner rotates once around your head
3. The scan captures all necessary data in approximately 10 to 20 seconds
4. Images are available immediately for Dr. Brumbaugh to review with you on a chairside monitor

There is no injection, no dye, and no special preparation. Most patients are surprised at how fast and simple the process is.

Part of Our Integrated Workflow

CBCT data integrates directly with our digital treatment planning software. For implant cases, the 3D model guides precise placement angles and depths. For complex restorative cases, it informs how CEREC restorations and full-mouth reconstruction plans are developed. This connected workflow reduces guesswork and improves outcomes at every stage of care.
