CBCT stands for Cone Beam Computed Tomography, which is a specialized imaging technique used in dentistry. It provides three-dimensional images of the patient's oral and maxillofacial structures, including the teeth, jaws, temporomandibular joints (TMJ), sinuses, and surrounding tissues.

CBCT scanners utilize a cone-shaped X-ray beam that rotates around the patient's head, capturing multiple images from different angles. These images are then reconstructed using computer algorithms to create a detailed 3D representation of the patient's oral anatomy.

CBCT imaging has become an invaluable tool in dentistry due to its ability to provide high-quality and accurate images with a lower radiation dose compared to traditional medical CT scans. It offers dentists and oral surgeons a more comprehensive view of the patient's oral and facial structures, allowing for better diagnosis, treatment planning, and evaluation of various dental and maxillofacial conditions.

Here are some specific applications of CBCT in dentistry:

  • Dental Implant Planning: CBCT scans provide precise information about the available bone volume, bone quality, and proximity to vital structures (such as nerves or sinuses). This helps in accurate implant placement planning, reducing the risk of complications and improving the success rate of dental implant procedures.

  • Orthodontics: CBCT allows dentists to visualize the position of teeth in three dimensions. It helps in identifying complex anatomical issues, such as impacted teeth, supernumerary teeth, or abnormal root positions

  • Endodontics: CBCT can assist dentists in diagnosing and treating root canal-related issues. It helps in identifying the number, length, and curvature of the root canals, detecting fractures, and assessing the success of the treatment.

  • TMJ Analysis: CBCT imaging provides detailed information about the temporomandibular joints, which are crucial for jaw movement. It helps in evaluating joint disorders, such as osteoarthritis, disk displacement, or structural abnormalities, enabling more accurate diagnosis and treatment planning.

  • Maxillofacial Trauma and Pathology: CBCT is valuable for assessing facial fractures, dental trauma, and various pathological conditions, including cysts, tumors, and infections. It aids in evaluating the extent of damage, planning surgeries, and monitoring treatment outcomes.

It's important to note that CBCT scans should be used judiciously, as they involve radiation exposure. Dentists carefully weigh the benefits against the risks and follow appropriate guidelines to ensure patient safety.
