i-CAT 17-19 Imaging System


iCatby Dr Vas Srinivasan, Invisible Orthodontics, Hervey Bay, QLD

Historically, dentists used a wall-mounted X-ray unit that produced two-dimensional results. Not only did that system have limitations with patients who gag, but the image could be distorted, elongated or shortened. A lot of guesswork was required to interpret the results. This cone beam imaging system has successfully solved all those problems.

What’s good about it

The results from the i-CAT require no imagination and completely eliminate any guesswork. The images are perfectly clear and the treatment outcome for the patient is far more reliable. The cone beam also limits the radiation to one specific area rather than scatter it across the whole head.

The image can be colour-coded to contrast and differentiate various parts of the mouth and jaw. The image is presented at a scale of 1:1 so what we see is a very accurate representation. The image can also be rotated and viewed from all angles.

The results are created very quickly, depending on the quality you require. High-quality, high-resolution images take about 28 seconds. A lower-resolution, straightforward scan can take as little as four seconds.

While two-dimensional X-rays were fine in the past, cone beam technology has vastly improved dental imaging. I doubt there will be a practice in Australia relying on 2D within the next 10 years.

What’s not so good

I would love it if I could scan just a single tooth so the radiation exposure was as minimal as possible. However, the cone beam results are so clear and unambiguous, I think the low dose of radiation is a very acceptable risk. This machine is also very expensive and may be beyond the reach of smaller practices.
