Correction: Koenig et al. Characterisation of the Filler Fraction in CAD/CAM Resin-Based Composites. Materials 2021, 14, 1986

Error in Figures

In the original publication [1], there was a mistake in Figures 2 and 3 as published: wrong unit (mm) in the x-axis. The corrected Figure 2 and Figure 3 with the correct unit (µm) in the x-axis appear below.

Error in Table

In the top line of Table 4 was a mistake: Incorrect abbreviations 3LUA, CBCA, and SBA. The correct abbreviations in

Table 4. Properties of local discontinuities identified by µXCT in CAD/CAM RBCs (HT).

are 3LU, CBC, and SB. The correct Table 4 appears below:

Error in Supplementary Materials

In the original publication, there was a mistake in Tables S1–S3. The presented units of ferret diameter were incorrect and were revised from mm to µm.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
