3D X-ray Scanning

As in medicine, 3-dimensional imagining has transformed the way we can make diagnoses and plan treatments. There are specific reasons for using 3D x-ray scanning because the x-ray dose is considerably more than the normal 2D radiographs which are used on a more frequent basis. We use a 3D x-ray scanner to assess and plan treatment with dental implants, complex root canal treatments and removal of wisdom teeth and cysts.

The 3D x-ray scanners used in dentistry use cone beam computed tomography (CBCT). The x-ray dose is usually much less than a medical CT scan because we do not need a lot of detail of skin, muscle and other soft tissues.

Our CBCT scanner is a Vatech Pax i-3D. It takes high quality scans which is ideal for using the latest digital work flow with dental implant planning. Our CBCT scanner does everything we need it to do and we even have referrals from other specialists when they require a highly detailed, high resolution scan, especially for difficult root canal treatment cases.

The CBCT machine builds a 3D model of the scanned area. We then use specialist software to look at a 3D reconstruction, or cut sections through the model at any desired point to identify important anatomical structures. This ultimately helps us to keep treatment complications to a minimum.

This is a screenshot of a CBCT scan to investigate a patient’s front teeth following an injury. The top left picture shows a cross section horizontally through the patient’s teeth. The pictures on the right are sections taken through the upper jaw which show reconstructed slices of a single tooth at 0.5mm intervals. The voxel (a 3D pixel) size of the scan was 0.08 x 0.08mm.
