3D imaging is well on its way to becoming the new standard of dental care!
The CBCT (Cone Beam Computed Tomography) is an innovation of the CT technology. With only a single scan of the CBCT machine, dentists can see more than just a regular xray. This is because 3D scans can catch problems 2D scans simply cannot by differentiating between different types of tissues in 3 dimensions.
Once the projected images have been acquired and collected, the 100 to 600 images are taken and used to construct a 3D model of the skull.
CBCT provides a fast, non-invasive way of answering a number of clinical questions. This may help with the diagnosis, treatment planning and evaluation of certain conditions in all fields of Dentistry.
Although the radiation doses from CBCT imaging are largely lower than other CT scans, the CBCT typically delivers more radiation than conventional dental X-ray exams. Hence It is not indicated for every single case that walks into the dental office, however there are some cases where 3D imaging is needed and the benefits outweigh the risks; for example in dental implant planning.
In Implantology, CBCT aids the dentist in assessing the area and surrounding structures where the dental implant is to be placed. This improvement in care means an extension of the life of your teeth and an improvement in the quality of your implants and crowns!
In Orthodontics the CBCT is beneficial in diagnosis, assessment and analysis of face, jaw and bone problems and airway passages. The 3D scan makes it easier to assess tooth-jaw relationships and to appreciate the patient’s facial aesthetics.
In Endodontics CBCT greatly benefits dentist and the patient in locating tooth infections to certain teeth, viewing broken instruments inside roots and showing all the canals in a tooth clearly.
In Oral and Maxillofacial Surgery, the CBCT imaging shows dentists precisely where and how far the lower jaw nerve passes below the teeth so as to avoid injury to the nerve during wisdom tooth removal. It helps to better assess the TMJ for bone and joint diseases that are not able to be appreciated on regular 2D imaging. Impacted teeth, facial tumors and facial bone fractures are also better assessed using CBCT imaging.
CBCT 3D imagine allows for accurate diagnosis to be made leading to successful treatment planning and therefore is a win win situation for the dentist and the patient altogether.
