3D Dental CT is a radiological test used to study the layers or sheets of a certain volume of the same tissue. 3D Dental Imaging is very effective in detecting oral conditions. It is often used when planning surgery, evaluating the jaw or sinuses, and even in reconstructive surgery, such as dental implants.
How does 3D Dental Imaging work?
First, we must understand that, unlike the 2D scanner, 3D technology allows you to have a vision in 3 dimensions, which allows you to consider the depth. Instead of capturing in pixels a square (length x height), radiography can capture in a voxel a cube (length x height x depth). This is enabled by cone cut technology rather than fan cut.
Steps on how to X-ray a patient using a CBCT:
· Positioning: positioning the patient is much easier with 3D technology since the precision has much less influence on the image quality than in the case of panoramic
· Acquisition: First, the examination area must be determined precisely, as the image resolution is much higher than 2D. You will probably need large storage space for the same expected image quality.With 3D CBCT, only a single 360 rotation is required, not TAC technology.
3D Dental Imaging at Beaufils Dental
At Beaufils Dental, we have completely digital 3D scanner equipment, which uses CBCT technology (Cone Beam Computed Tomography). Perform volumetric dental images in record time. In addition, it can create a life-size image of your teeth, mouth, and jaw, giving your dentist very accurate measurements.
How is 3D Dental Imaging carried out?
The 3D dental scanner uses an arm that rotates around the patient’s head. While rotating, it captures multiple images and sends them to a computer arranged in 3D format. Dentists get a very clear and concise picture of tissue layers that cannot be seen with the naked eye, making it easy for them to diagnose and even personalize their treatment confidently.
Types Of Dental CT:
There are different types of maxillofacial CT. Among them are:
· Bimaxillary CT: This is a radiological examination of both maxillary bones. It allows the evaluation of dentoal velour structures and the diseases or pathologies that affect them and fractures and tumors, especially those of odontogenic and bone origin. Before third molar extraction, dental implants, cysts, tumors, fractures, and orthogenetic surgery it is recommended.
· TAC Maxillary (upper arch) / Mandibular (lower arch): It is indicated for the implant study, dental extractions, or evaluation of pathologies in the upper or lower jaw bone. It does not require any preparation before the test, and the scan time does not usually exceed 10 minutes.
· CT by Sextant or Dental Quadrant: The dental arches can be divided as follows: arches (upper or lower jaw), heresiarchs or quadrants (each arch is divided into two hemiarchs, two upper and two lower), and sextants (each dental arch can be divided into three sextants so that we would have three uppers and three lower).
· Periapical or tooth CT: This would be performed on a single tooth. This technique makes it possible to see the lesions that the intraoral periapical radiography does not show us.
· Paranasal Sinus CT (maxillary sinuses): the most accurate imaging technique to determine if the paranasal sinuses are obstructed, and it is the best imaging modality for sinusitis.
· CT of TMJ (Temporomandibular Joint): The temporomandibular joint or TMJ is the joint between the temporal bone and the mandible. CT or CBCT of TMJ is the diagnostic test of choice in evaluating fractures, ankylosis, tumors, and developmental disorders.
Recommendations:
Because children are more sensitive to radiation, they should only have a CT exam if critical to making a diagnosis and should not have repeated CT exams unless necessary. CT scans in children should always be done with the low-dose technique.
The Advantages Of Using 3d X-Rays
A particular 3D Dental Imaging is sufficient for the entire image of the oral structure. The dentist can easily look at the image from various points of view. Thanks to its pulsed and non-continuous radiation, the cone beam reduces radiation to the patient by 60%.
Dental Imaging is recommended for the treatment of dental diseases, implants, restorations or surgical interventions, and the extraction of wisdom teeth. Environmentally friendly, it does not use developer chemicals.
