What is CBCT Cone Beam Imaging?

There was once a time in periodontology and related fields that diagnosis was limited to 2D imaging devices. The use of 3D modalities was rare due to the amount of radiation used. 3D imaging using computer tomography had been available, but its use was reserved for special or serious cases. Enter CBCT cone beam imaging: cheaper, less bulky, and, most important of all, less radiation.

The CBCT is a variation of the traditional CT scan. It rotates around the head of the patient using a cone-shaped X-ray beam. The resulting images are used to recreate a 3D image of the patient’s mouth, teeth, and maxillofacial region.

What the Patient Can Expect During the Scan

The patient should wear loose-fitting clothing on the day of their CBCT cone beam scan. In some cases, dental professionals may provide a hospital gown. Any metal objects, including jewelry, glasses, barrettes, or dentures, should be removed before the process. The patient should make the practitioner aware if they are pregnant or have any metal in their body that cannot be removed. Fillings in the mouth should not pose a problem.

The dentist will ask the patient to either stand or sit in the exam chair. The patient will need to be perfectly still during the scan and not talk or swallow. The X-ray detector will revolve around the patient in a 360-degree rotation. This scan will be over in a minute or less.

Frequently Asked Questions About

What is it like to get a CBCT cone beam scan?

Many people find the scan to be comfortable and quick. Patients may have to stand during the scan, which will only take around a minute. Also, this will not interfere with your day because you can get back to your normal activities right away.

Does dental insurance cover this type of scan?

While each insurance plan is different per patient, most may not cover this type of scan.However, the industry seems to be slowly deciding to cover this work. It is always a good idea to check with your insurance provider first. Sometimes, if an uncovered test is deemed necessary by the patient and the dentist, it may be possible to arrange payment plans.

What was used before CBCT Cone Beam Imaging?

CBCT is a variation on the CT scan. The CBCT scan captures more in a single turn and takes less time. Also, CBCT exposes patients to less radiation than the CT scan.

How does the traditional CT scanner compare in image quality to the CBCT scanner?

The higher-level 3D images are more accurate than the CT. According to Dental Economics CBCT adds depth, thus giving the clinician multiplanar views of the volume. This further improves diagnostic abilities and reduces the need to take multiple X-rays.

Can CBCT cone beam scans be used on children?

The current debate on this issue leads to no. Though it still has significantly less radiation than the traditional CT scanner, more work needs to be done to make it even safer. It should only be used on children if considered necessary for the diagnosis and treatment plan of something serious.

How has the patient’s experience improved?

Patient experience has improved immensely. Not just because of the speed and comfort. It is easier for the dentist to communicate with the patient by showing them an accurate three-dimensional image of their jaw. For example, a dentist can show where an implant can be placed in a patient’s jaw using imagery that makes it clear to the patient.
