CBCT has the following advantages over conventional CT:
1. Extremely low radiation levels
For most patients, the main reason for refusing to undergo CT is the fear of X-ray radiation. This is true, and it has even been reported that the amount of radiation from a single CT is equivalent to 500 chest X-rays. Compared with the traditional multi-row spiral CT, the dose of CBCT is related to the size of the window, generally equivalent to 1/60-1/100 of the traditional CT radiation, which is only equivalent to the radiation of 1 oral panoramic film, which completely solves the patient's worries. In addition, pediatric patients in stomatology account for a large proportion of patients, such as adolescent orthodontic patients, congenital malformation of jaw development and congenital OSAS patients, etc., and children's ability to absorb radiation is 10 times that of adults, so for the stomatology department, the CBCT with extremely low radiation compared to conventional CT undoubtedly has a great advantage.
2. Clearer imaging of teeth and jaws
CBCT has better imaging quality for hard tissue structures such as teeth or jaws, with a layer thickness of only 0.1mm, and can even show small cracks in the roots of the teeth, which is more suitable for stomatology treatment. CBCT can show the number of root canals more clearly, and can detect the mutation of small root canals, early apical inflammation and root fracture which cannot be determined by traditional examination.CBCT can accurately detect the amount of alveolar bone resorption, so that the severity of periodontal disease can be assessed in a non-invasive condition. CBCT can observe the curvature of the tooth root and its relationship with important anatomical structures such as the maxillary sinus, the floor of the nose, the inferior alveolar nerve canal, and the chin foramen, which facilitates the surgeon's preoperative evaluation before tooth extraction. It is also possible to observe the extent of the jaw cyst in three-dimensional space and understand the relationship of the lesion to the maxillary sinus, neural tube and other important anatomical structures. In oral implantation, the doctor can accurately analyze the bone quality, bone volume and relationship with neurovascularity in the implantation area through CBCT scanning, so as to determine the implant width, length, implantation direction, and the amount of bone needed to be implanted, and to improve the success rate of implantation surgery.
3. Simple operation
CBCT is not like the traditional CT operation requires professionals to hold a license, and its post-processing is also basically completed by the dental clinicians. CBCT has its own special software to make it more convenient for stomatologists to use, and stomatologists can completely according to their own wishes to obtain their own dental or jawbone images, homemade three-dimensional reconstruction of imaging, without the need for further CT technicians. This saves manpower and resources, and avoids errors caused by inconvenient communication between doctors and technicians. At the same time, it is also convenient for our doctors to save clinical data for scientific research.
