Clinical Feature
CS MAR reveals
pathology and reduces
risk of misinterpretation
Carestream Dental’s CS 8100 3D features the CS MAR (Metal
Artifact Reduction) technology, which drastically reduces metal
artefacts caused by dental restorations, implants, and fillings.
As discussed by Dr Hanke Faust, this feature compares images
dynamically to obtain a more accurate and advanced diagnosis.

A 50-year-old patient with extended
soft tissue swelling around teeth 43
and 44 came to the practice (Figs.
1-2). The patient reported no pain
and irritability on the lesion but the
panoramic image revealed multiple
coronal and apical pathological
findings (Fig. 3). An extraoral image
was captured with the CS 8100 3D.

A CBCT volume was taken with
a 150-micron resolution for
further diagnostics using the FDK
reconstruction, as well as the new
CS MAR (Metal Artifact Reduction)
algorithm, which greatly increased
the spectrum of diagnostic
possibilities. The 3D view revealed
osteolysis (Fig. 4).

When comparing the panoramic
images extracted from the 3D scan
(Figs. 5-6), the image with CS MAR
applied (Fig. 6) showed significantly
lower artefacts caused by implants,
fillings and dental crowns. Various
pathological findings, such as apical
brightening at teeth 15, 26, 37 and
47; coronal brightening at teeth
15 and 45; and osteolysis at 15, 43
