CS 8200 from Carestream Dental, consistently superb dental diagnostic images

In dentistry good quality diagnostic images are essential. However, image acquisition isn’t always straightforward due to a number of variables that directly impact image quality. These must be overcome in order to avoid the need for retakes.

A study that examined frequency of retakes during CBCT image acquisition found that the retake rate was 4.6% [1] and while this may not sound like a huge ratio, it still wastes valuable time. We also need to consider the levels of radiation exposure that come into play after too many retakes. While dosage is minimal in most modern machines, radiation is cumulative, meaning the fewer attempts at image acquisition the better.

The main problems that can impact image quality?

One of the more recurrent problems during image acquisition is incomplete file-of-view (FOV) coverage. Data suggests that 57.5% of retakes result from this problem, which usually occurs when clinicians select the incorrect FOV for the area they want to diagnose. The best way to bypass this problem is to invest in a system that has multiple FOVs available, meaning you can assess which dimensions best suit your needs for the initial scan.

Another common problem stems from patient positioning and movement. The aforementioned study into CBCT retakes found that 27.5% of retakes were due to motion artifacts caused by a patient making a sudden movement or not being properly positioned. It is best to take the time to position patients carefully while explaining to them why absolute stillness is necessary. Some modern systems have inbuilt software that aids patient positioning, which can significantly improve imaging outcomes.

Some nervous patients might find it difficult to remain still and it’s crucial to talk with them and try to allay their fears. Explain what the process involves and give them the time they need to calm down before image acquisition. Consider investing in a system such as the CS 8200 3D CBCT unit from Carestream Dental which has face-to-face position and can be adjusted to accommodate seated patients to help them feel less enclosed, more comfortable, and at ease.

According to recent statistics, 84% of dentate adults in the UK have at least one filling [2]. We don’t know how many of these are amalgam, precious metals, composite and other filling materials, but it can safely be assumed that a large percentage of the population have metal fillings and crowns in their mouths.

These metal artifacts cause another common imaging problem. Metal restorations reflect and distort the beams used during CBCT scanning, which shows up on final images as bright patches of light or heavily blurred areas that render the images unusable.

The cutting-edge CS 8200 has Carestream Dental’s unique CS Mar software, drastically reducing the effects of metal artifacts, reducing the risk of misinterpretation and the need for retakes. Resolving all the problems listed above this superb CBCT system offers low dose imaging, multiple selectable FOVs, laser-free patient positioning and more.

Precise diagnostic images are a crucial part of treatment, it pays to invest in systems that help you to navigate and avoid the common pitfalls that might impact image quality. The CS 8200 not only ensures you have the technology you need to capture incredibly accurate and artifact-free images, but also provides a streamlined, comfortable patient journey with significantly reduced need for image retakes.
