CBCT: It’s Importance in Dentistry and How It Enhances Implant Treatments

Dental CT (computed tomography) scanners are indispensable in dentistry as they ensure the accuracy and ease of dental investigations. Technology has rapidly improved in the last decade, so a growing number of dentists are relying on it to accurately diagnose and treat their patients. However, due to ionizing radiation, there is concern over its effects on increasing the risk of developing cancer over time. Because of this, discerning dentists are looking into other dental CT scanning equipment while following the As Low As Reasonably Achievable (ALARA) principle. That way, they can continue using the technology while minimizing their patients’ exposure to high amounts of radiation. CBCT is one of the alternatives to conventional dental CT scanners.

CBCT stands for ‘cone beam computed tomography.’ Its total radiation doses are about 96 percent lower than regular CT exams. Although they deliver more radiation compared to the regular dental 2D x-ray, the time of exposure to radiation during a CBCT is comparatively less—as long as the smallest possible FOV (field of view), the shortest exposure time, the lowest mA setting, and the smallest voxel size are utilized. It is also important to make sure that the dentist prescribing the procedure is qualified to do so. Check their credentials, especially when CBCT is being prescribed before implant treatments.

When regular facial or dental x-rays are insufficient, CBCT is recommended because it provides a three-dimensional look at the contours and dimensions of the jaw and the bone structure, as well as the teeth. One of the more common applications of CBCT in dentistry is the examination of the jawbone to ensure accuracy in dental implant placement and determining tooth orientation and bone structure. It is also used when surgery needs to be planned for extractions in the case of impacted wisdom teeth, reconstructive surgery, and in diagnosing TMJ.

CBCT is one of the contributing factors to the improvement of implant treatments over the years, as it aids in implant planning. For this purpose, the imaging uses 3D and multi-planar images to determine the exact width, alveolar ridge anatomy, and height of the alveolar bone and how the edentulous sites are related to the adjacent structures. The accuracy of implant placement surgery can also be guided by the data produced by the CBCT. Likewise, the 3D imaging can help dentists understand if bone grafting and other pre-prosthetic surgery may be needed before implants are placed.
