One of the superior x-rays available is the CBCT scan. Many people have not seen this machine before, but continue reading to learn more. 

This article will answer many questions so you can feel comfortable about this imaging procedure. Doctor Clayman at Pinole Oral Surgery has years of experience in completing these scans, along with all-on-4 dental implants and all-on-4 cleanings. We are located conveniently in Pinole, CA, for all your dental needs. 

What is a CBCT Scan?

These letters stand for cone-beam computed tomography. An x-ray source in the design of a cone rotates entirely around your head. While rotating, it takes multiple high-quality images of your mouth and jaw that combine to create a precise 3D image. 

The cone-beam CT scan is different from a conventional CT scan. It reduces scattered radiation, so that image quality is increased. It is also a smaller machine that can be used in dental offices for the patient’s convenience. 

What Does A CBCT Scan Show?

A CBCT scan can enhance the accuracy the surgeon has with your procedure. Below are some of the things your dentists will search for in CBCT imaging.

  • Nerve pathways
  • Jawbone
  • Infections or disease
  • Dental caries (cavities)
  • Tooth decay
  • Bone structure
  • Sinus and nasal cavity 
  • Details of soft tissues

Do I Need A CBCT Scan? 

If you are getting any implants, the answer is probably yes! This type of imaging technology is suggested to ensure the successful placement of dental implants. Before you get all-on-4 implants or a conventional dental implant, a treatment planning stage is always done. 

Before all-on-4 dental implants, the dentist needs to see bone height, structure, density, and critical nerve paths. The cone-beam CT will show just that. With this vital information, your dentist can pinpoint possible complications and work to minimize them before your dental implant procedure. This way the procedure is guaranteed to go smoother and easier. 

What Other Reasons Will I Need A CBCT?

Although a cone-beam CT scan is vital for a dental implant procedure, it may be used for many other things. It will allow your dentist to take a deeper look for evaluation or diagnosis. Here are a few other procedures you can expect to have a cone-beam CT for:

  • Reconstructive surgery 
  • Locating pain or disease
  • Cephalometric analysis
  • Detecting oral or facial tumors 
  • Evaluation and diagnosis of TMJ Disorder

What Can You Expect During A CBCT Scan?


Preparation is little to none. It is quick for most patients and takes just a few minutes. In some cases, an all-on-4 dental cleaning is done to make certain we get clear images, free of any food debris. Before the procedure, you will need to remove your jewelry, any metal devices, or glasses so it does not interfere with the x-ray beam. In addition, we will put you in a lead vest to protect you from the radiation.


A CBCT scan is painless and should cause you no discomfort. In most machines, you will be fitted with a stabilizer on your head to keep it still. In some cases, you may be asked to bite a stick that will position your jaw for imaging. The machine will then rotate around your head. 


The cone-beam CT scan image is available almost instantly, then your dentist can analyze it. You may come back for another visit, so your dentist can have time to plan and search through the CBCT scan for the needed information. 

Who Should NOT Get A CBCT Scan

It is not best for everyone to receive this type of x-ray. It can depend on your age and healthcare history. If you are pregnant or you might be pregnant, be sure to make your dentist or his assistant aware before the scan. 

Pregnant patients are not advised to have these scans because of the risk involved. There is a small risk the fetus could be harmed from the radiation exposure. It’s always better to be on the safe side. If you are pregnant we will evaluate you in another way or wait until after you give birth.
