Cone-beam computed tomography (CBCT) is a medical imaging technique that uses x-rays to create highly accurate and detailed three-dimensional (3D) images of the inside of an object. These 3D images provide information that traditional x-rays cannot capture, allowing us to diagnose and treat problems with greater accuracy and precision. This can be helpful for a variety of dental procedures, including root canals and dental implants.
Cone-beam CT scans use a lower dose of radiation than conventional CT scans, while providing a higher resolution. This can be especially important for children and other individuals who may be more sensitive to the effects of radiation.
The cone-beam computed tomography (CT) scanning process is typically performed in a dental office or clinic. The process typically involves the following steps:
- The patient is seated in a comfortable position and positioned in front of the cone-beam CT scanner. The scanner typically consists of a rotating X-ray source and a specialized X-ray detector.
- The patient is asked to remain still during the imaging process.
- As the X-ray source rotates around the patient, it emits a cone-shaped beam of X-rays, which passes through the object being imaged (the teeth, jaws, and surrounding tissues).
- The attenuation of the X-rays is detected by the X-ray detector and used to create a series of 2D images at different angles of the object.
- These 2D images are then combined and processed by specialized software to create a detailed 3D representation of your mouth.
- The resulting 3D image can be viewed on a computer screen and used by the dentist to evaluate the patient’s dental health and plan treatment.
Some of the most notable uses include:
- Implant placement: CBCT provides information on the width and density of bone, as well as nerve location. This allows us to plan and execute your implant surgery with greater accuracy and reduced complications. Traditional implant surgery required major incisions and flaps in your gums in order to visualize the bone. Combining CBCT and intraoral scans, we can provide minimally invasive, guided surgery. This means less pain and bleeding after surgery.
- Root canals: CBCT provides 3D information on the nerves inside a tooth. This allows us to see the number of canals, canal placement, and unusual anatomy. This allows to to provide root canals with greater success.
- Diagnosis: Often, dental problems cannot be detected in traditional radiographs. CBCT improves our ability to diagnose vertical and horizontal root fractures, infections hidden behind other roots or the sinus, and more.
Overall, cone-beam CT has become an important tool in the field of dentistry. The process is quick and non-invasive, enabling us to provide more accurate and effective care to our patients.
