What is CBCT?

CBCT (Cone Beam Computed Tomography) is an advanced imaging technique that provides 3D images of the teeth, soft tissues, nerve pathways, and bone structure. It is commonly used in dentistry to obtain highly detailed views of the oral and maxillofacial regions.

How it works

Unlike traditional 2D X-rays, CBCT uses a cone-shaped X-ray beam that rotates around the patient to capture multiple images from different angles. These images are then compiled into a 3D representation for precise diagnostics.

Benefits of CBCT in Dentistry

  • Higher Accuracy: CBCT provides 3D images that allow for more accurate diagnosis and treatment planning compared to traditional 2D X-rays.

  • Enhanced Treatment Planning: It is especially useful for planning complex dental procedures like dental implants, root canal therapy, and orthodontic treatments.

  • Detailed Visualization: CBCT helps in visualizing bone structure, impacted teeth, cysts, tumors, and infections that may not be visible in conventional X-rays.

  • Minimally Invasive: With its precise imaging, CBCT reduces the need for exploratory procedures and surgeries, making treatment less invasive.

  • Reduced Radiation Exposure: CBCT typically delivers less radiation compared to traditional CT scans, making it a safer alternative for dental imaging.

Common Uses of CBCT in Dentistry

  • Dental Implants: CBCT is essential for implant placement as it helps to assess bone quality and quantity, as well as the position of nerves and sinuses.
  • Orthodontics: CBCT assists in evaluating tooth eruption, jaw relationships, and potential issues with alignment and bite.
  • Endodontics (Root Canals): CBCT provides a detailed view of root canal anatomy and any surrounding structures that might impact the procedure.
  • Periodontics: It aids in assessing the bone structure around the teeth, detecting periodontal disease, and evaluating tooth mobility.
  • Oral Surgery: CBCT is used to assess impacted teeth (like wisdom teeth), jaw anomalies, and other surgical cases.
  • TMJ Disorders: It is also useful for evaluating temporomandibular joint (TMJ) disorders and the surrounding bone structures.

CBCT vs Traditional X-Rays

2D X-Rays: Traditional X-rays provide flat, 2D images of the mouth and teeth, which can sometimes miss hidden problems or fail to capture the full depth and complexity of an issue.

CBCT: In contrast, CBCT produces 3D images that allow dentists to view structures from different angles, providing a more complete picture and enabling more precise treatment planning.
