Purpose: This ex vivo study was performed to determine the optimal energy level for virtual monoenergetic images (VMIs) generated with photon-counting detector computed tomography (PCD-CT) to minimize metal artifacts from dental implants. Materials and Methods: Twelve implants from various manufacturers were placed in 6 pig mandibles and scanned with PCD-CT. VMIs were reconstructed at energy levels from 70 keV to 150 keV in 20-keV increments. Three readers with varying experience qualitatively assessed the image quality, artifact burden, and diagnostic interpretability of peri-implant soft and hard tissues using a 5-point discrete visual scale. Objective analyses included quantitative line profileanalysis of implant-induced artifacts. Descriptive statistics were calculated, and inter-reader agreement was assessedusing percentage agreement and the Krippendorff alpha coefficient. Results: Qualitative analysis demonstrated excellent image quality for VMIs at ≥110 keV (median = 5), with minimal artifacts observed at 130-150 keV. In contrast, lower-energy VMIs (70-90 keV) showed inferior performance due to artifact-related limitations in diagnostic interpretability. Inter-reader agreement ranged from moderate to perfect, with perfect reliability (α = 1) for VMIs ≥110 keV. Quantitative line-profile analysis confirmed reduced artifact burden at higher energy levels, particularly for VMIs ≥110 keV. Conclusion VMI at energy levels ≥110 keV on PCD-CT reduced dental implant-related metal artifacts and offeredexcellent image quality, including assessment of both peri-implant soft and hard tissues. These findings suggest thatoptimized PCD-CT VMI may enhance postoperative follow-up imaging. Future in vivo studies are warranted tovalidate these findings in clinical practice.
