Unveiling Advanced Dental Imaging: Cone Beam CT (CBCT)
At Dental Arts we pride ourselves on offering cutting-edge technology to provide our patients with the best possible care. Our latest addition, the Dental Cone Beam Computed Tomography (CBCT), is a specialized type of X-ray machine used in scenarios where traditional dental X-rays fall short. This advanced diagnostic tool allows us to obtain detailed images of your oral and maxillofacial structures, enabling precise and effective treatment planning.
What is Cone Beam CT?
Cone Beam CT is an advanced imaging technique that uses a unique cone-shaped X-ray beam to capture extensive three-dimensional (3-D) images of your dental structures, soft tissues, nerve paths, and bones in the craniofacial region—all in a single scan. This technology provides a comprehensive view that traditional dental X-rays cannot, making it an invaluable tool in diagnosing and planning treatments for various dental conditions.
Cone Beam CT vs. Traditional Dental CT
While both Cone Beam CT and traditional dental CT scanners create 3-D images of the jaw, the technology behind them is quite different:
- Traditional Dental CT: Uses a fan-shaped beam to transmit radiation in a spiral pattern.
- Cone Beam CT: Utilizes a cone-shaped beam that rotates around the patient's head, producing 150 to 200 high-resolution 2-D images. These images are then combined to form a detailed 3-D model.
This innovation allows us to review intricate cross-sections of your head and neck, identifying issues with greater precision.
Benefits of Cone Beam CT
- Enhanced Diagnostic Capability: Accurately identifies diseases of the jaw, dentition, bony structures of the face, nasal cavity, and sinuses.
- Reduced Radiation Exposure: Utilizes lower power levels compared to traditional dental CT, resulting in significantly less radiation exposure—200-300 times less during panoramic radiography.
- Comprehensive Imaging: Provides a full mouth X-ray in about 15-20 seconds and regional scans in under 10 seconds, offering a quick and painless experience.
Common Uses of Cone Beam CT
Cone Beam CT is particularly useful for:
- Dental Implants: Ensures accurate and safe placement of dental implants.
- Surgical Planning: Assists in planning surgeries for impacted teeth and reconstructive procedures.
- Diagnosing TMJ Disorders: Evaluates temporomandibular joint disorders.
- Evaluating Jaw and Sinuses: Provides detailed views of the jaw, sinuses, nerve canals, and nasal cavity.
- Locating Pain or Pathology: Finds the origin of unexplained pain or pathology.
- Orthodontic Planning: Helps in planning complex orthodontic treatments.
Preparing for Your Cone Beam CT Exam
No special preparation is required for a Cone Beam CT exam. However, for your comfort and convenience, please consider the following:
- Dress Comfortably: Wear loose-fitting clothing.
- Remove Interfering Objects: You may be asked to remove jewelry, eyeglasses, hairpins, and hearing aids before the exam.
- Inform About Pregnancy: Women who are or might be pregnant should notify the dentist or oral surgeon to take proper precautions.
During and After the Procedure
The procedure is simple and painless:
- Positioning: You will be asked to stand or sit in the Radiology room. The dental assistant will position you to ensure the area of interest is centered in the beam.
- Imaging: The X-ray source and detector revolve around your head, capturing high-resolution images.
- Duration: The entire process typically takes about 15-20 seconds for a full mouth scan and less than 10 seconds for a region
