CONE BEAM 3D CT SCAN
The CBCT scan is a low dose scanning system, which is specially made to produce 3D images of the maxillofacial skeleton, and improve various conventional X-Ray procedures in dentistry. It allows the doctor to see visualize pathogens.
How does it work?
CBCT scanners utilize back-projection reconstructed tomography for acquiring data of interest. It is done with the help of single or partial rotation of the X-ray beam and reciprocal image receptor. The scan time is less than 20 seconds. Traditional CT acquires images with the help of a row of detectors, whereas CBCT shows the whole section of the patient with only one detector. They utilize less compact and cheaper solution than traditional CT scanners but deliver better image quality.
More precision in Dental implants
Conventional x-ray involves hindrances in the evaluation of the neighboring bone and soft tissue before the implant is placed. Whereas, CBCT technology gives less distorted information. It shows bone height and width with more precision. This decreases the chances of nerve damage of the lower jaw by accurately locating it before the implant. For the upper jaw, 3D images result in a better picture of the maxillary sinus, and neighboring structures, for placing the implant.
Uses of CBCT
CBCT performs the following functions-
- Assessing the jaw for placing the dental implants.
- Orthodontics uses it for 3D cephalometry, the examination of teeth, and structures of the face for planning the course of treatment.
- Temporomandibular joint imaging
- Assessment of the impacted teeth done before the operation and evaluation of the distance of the lower Wisdom teeth from the mandibular nerve before extraction is done.
- Identifying the need for Root fracture or periapical disease in the teeth.
- Finding signs of infections, cysts or tumors in the bone.
- Assessment of bony and dental pathologic conditions, like fracture and structural maxillofacial deformity
