Regarding the paper "Evaluation of the effect of reducing metal artifacts in multi-detector CT imaging of zirconia and titanium implants" accepted: February 17, 2025.

I am writing to raise concerns regarding the above-mentioned paper, specifically related to the phantom used in the study "Evaluation of the Effect of Reducing Metal Artifacts in Multi-Detector CT Imaging of Zirconia and Titanium Implants" Accepted: February 17, 2025 Oral Radiology https://doi.org/10.1007/s11282-025-00814-5 ". In this paper, the authors state that they created a phantom that I designed and commissioned a specialist company to create. This phantom was designed for CBCT, not CT, and was designed by me to reflect the shape of the mandible to some extent in CT scans, while minimizing artifacts about 15 years ago.　Our original paper was titled "Evaluation of Measurement Accuracy in Diagnostic Imaging Using Cone-Beam CT" and was published in the Journal of the Japanese Society of Oral Implantology (Yoshida Yuri, Morita Yasuhiko, et al., 2009; 22(1):3-14. It is available via open access.
