Modern dentistry is synonymous with advanced technology, which has significantly enhanced diagnostic capabilities and treatment planning for patients. Among the innovations that have redefined dentistry is dental cone beam computed tomography (CT) scans — a revolutionary tool that provides detailed 3D images of the oral and maxillofacial region. From pinpointing complex dental issues to aiding in surgical planning, cone beam CT scans have become commonplace in dental practices.

What is a Dental Cone Beam CT Scan?
A dental cone beam CT scan (CBCT) is a specialized imaging technique that uses cone-shaped X-ray beams to create a 3D representation of oral structures. Unlike traditional dental X-rays, which produce 2D images, cone beam CT scans provide very detailed, high-resolution images with minimal distortion. This technology allows dentists to view the teeth, jawbone, nerves, sinuses, and surrounding tissues from various angles, offering a more comprehensive view of the patient's oral anatomy and any issues.
When is a Dental Cone Beam CT Scan Necessary?
The need for a dental cone beam CT scan is tailored to each patient’s individual circumstances and dental health needs. For some, CBCT imaging may be an essential tool for regularly monitoring progress during ongoing treatments, such as orthodontics, implant placement, or complex restorative procedures. For others, it might serve as a one-time diagnostic tool to address a specific concern, like evaluating jaw structure, assessing bone density, or planning for a surgical procedure. This advanced imaging technology provides a comprehensive, 3D view that allows dental professionals to deliver precise and effective care tailored to the unique needs of every patient.
Dental cone beam CT scans are utilized in a variety of scenarios, including:
-
Implant Planning: Before dental implant placement, cone beam CT scans help assess bone quality, quantity, and location, aiding in implant positioning.
-
Orthodontic Treatment: Orthodontists utilize CBCT images to evaluate impacted teeth and plan orthodontic interventions.
-
Evaluation of Pathologies: CBCT scans are critical in diagnosing and evaluating cysts, tumors, infections, and temporomandibular joint (TMJ) disorders.
-
Surgical Planning: Oral surgeons rely on cone beam CT scans for accurate pre-surgical planning, for procedures such as impacted wisdom tooth removal and bone grafting.
How Does a Cone Beam CT Scan Work?
A cone beam CT scan is straightforward and typically only takes a few minutes. The patient is positioned standing or seated within the CBCT machine, which resembles a traditional dental X-ray unit, but with a rotating arm. The CBCT machine uses a cone-shaped X-ray beam that rotates around the patient’s head, capturing a series of detailed images from various angles. These individual images are then processed through advanced software to create a highly accurate 3D digital model of the patient’s oral structures. This model can be viewed, analyzed, and manipulated by the dentist or radiologist, providing an in-depth perspective to aid in diagnosis, treatment planning, and precision care.
What Diagnoses are Made From Cone Beam CT Scans?
Cone beam CT scans help dentists diagnose several oral health issues, along with a visual examination and understanding of the patient’s symptoms.
Dental professionals gather considerable information from cone beam CT scans, including:
-
Bone density and structure issues
-
Problematic eruption patterns of teeth
-
Soft tissue structure issues
-
Cysts, tumors, and abscesses
-
Impacted teeth
-
Oral infections
Are Cone Beam CT Scans Safe for Children?
Although dental cone beam CT scans are typically associated with adult care, they also play a crucial role in pediatric dentistry as valuable diagnostic tools. In children, CBCT scans may be used to assess dental and skeletal development, evaluate impacted or missing teeth, diagnose craniofacial anomalies, and aid in planning orthodontic treatments. However, given the heightened sensitivity of children to radiation exposure, pediatric dental professionals take great care to evaluate the necessity of CBCT imaging, ensuring the benefits of the scan outweigh any potential risks. This careful consideration helps provide safe, effective care tailored to young patients' unique needs.
