The first CTs were developed in the latter part of the 1980s, dental CTs have become a element of the standard set-ups in dentists’ clinics as well as hospitals. This is why they are commonly used in routine treatments, particularly when dealing with complicated cases or advanced dental techniques. The main dental CT structures it encompasses are teeth, root and soft tissue (tongue) as well as the lower and upper jaw bone, the temporomandibular joint, maxillary sinuses, nerves inside or around oral cavities and the airway and pharynx.

Some conditions could require a CT scan of the teeth

Your dentist will recommend an oral CT in the event that they require to examine more than what the dental X-ray could offer. Although CTs aren’t required to perform every routine dental checkup Be sure that your dentist will have reasons to request one. Here are a few situations which may require an dental CT.

  • Root canal therapy that fails. Extra canals that remain unnoticed are the main reason for a failed RCT. Dental X-rays show only one angle of teeth, and they are not able to recognize narrow or overlapped canals. This is why dental CTs can be extremely beneficial. They can identify gaps, narrow and untreated canals, increasing the chances of success for re-RCTs to nearly 90 percent.
  • Jaw joint assessments. Dental CTs are among the most efficient tools for assessing the joint’s alignment, position and any possible anomalies. Furthermore dentists can examine the cartilage, bones, and muscles surrounding the joint to provide the full view of what’s happening. If you’re experiencing discomfort in your jaws, swelling or jaw locks and jaw locks, the dental CT scan is extremely beneficial.

  • Detection of injuries. Dental CTs give dentists with clear images that make it much easier to detect fractures, evaluate the extent of the damage and plan surgical procedures. Because facial and oral fractures typically occur in tandem, CTs are helpful because they offer a clear complete and accurate model of the facial structures surrounding them. It’s a fantastic instrument to help a team of specialists for head-neck trauma, as well as cosmetic surgeons collaborate to solve a problem.
  • Implant positions. The successful placement of dental implants is dependent heavily on a thorough prior-operative examination of the location and surrounding structures as well as how implants will be placed within the bone. Additionally your dentist will have to maneuver around the vital nerves and arteries when placing the implants. This is the place where dental CT scans can help. Dental CT scans are high-quality images that have great clarity and display the bone’s structure as well as the texture and the quality. These scans can also be an excellent tool to determine whether you’re a suitable implant candidate initially.
  • The amount of tumors and cysts. Dental CT scans offer precise measurements, the location and growth rate for dental tumors and cysts. In addition, CT scans’ 3D images provide vital information regarding the form of a cyst, its boundaries, and potential the possibility of encroachment onto nearby structures.
  • Assessment of orthodontic treatment. Planning is a crucial step in orthodontics. So, orthodontic specialists rely heavily on CT scans to create customized treatment plans, identify the necessity for extractions and assess whether braces or aligners will work for the particular situation.

The dental CT is an interactive 3D representation of the mouth. It aids dentists in diagnosing and treat, identify, and track progression. And the best thing is it’s digital. It can be saved or retrieved and then transferred across different systems. This means that if you’re traveling or moving or going to a new dentist or continuing your treatment after a break Your dentist will be able to review a previous CT or forward it to the new dentist.

  2. These X-rays get recorded on an imager that is opposite to the source. When the scanner spins and takes pictures from a variety of angles. High-quality images are able to capture the smallest the details.
  3. It emits a narrow X ray beam, which is released that is shaped like a cone or fan. These X-rays appear invisible and may be absorbed by bones and teeth.
  4. Dental CT scanners come with an enormous C-arm with a circular design which spins around your head, akin to the spinning top.

Although it may seem simple, the millions of electronic devices within the scanners are operating together to create the perfect scan.
