“…The effect of various factors on artifacts in CBCT images has been investigated, including metal artifact reduction algorithm (MAR), implant material, voltage, implant position, voxel size, tube current, and field of view (FOV) [ 5 – 21 , 24 , 25 , 27 – 32 , 36 – 39 ].…”

“…According to [ 20 ], adaptive image noise optimizer (AINO) optimization filter was effective in reducing artifacts [ 20 ]. In Cardarelli et al's study in 2021, they investigated a new protocol called “low-dose CBCT imaging protocol” which was useful in reducing artifacts [ 39 ]. Based on [ 27 ], increasing the number of basis images was effective in reducing artifacts [ 27 ].…”

Objective. Dental implant artifacts can compromise the quality of cone-beam computed tomography (CBCT) scans and challenge radiographic detection in surrounding regions. This literature review was conducted to examine the impact of implant angle modification on reducing metal artifacts in CBCT scans. Materials and Methods. A scoping review of literature was carried out in PubMed, Embase, Scopus, and Cochrane databases. Results. Different spatial planes, including alpha, beta, gamma, and phi, along with 0°, 5.2°, 9.8°, 14.5°, 15°, 30°, 45°, 60°, 75°, and 90° angles were studied. Changes in the angular position of implants may reduce metal artifacts and improve the quality of CBCT scans. Conclusions. Rotating implants within the alpha plane and angling them at 90° in the alpha plane enables reducing dental implant artifacts.

Background Early accurate radiographic assessment of peri-implant bone condition is highly important to avoid excessive loss of supporting bone and implant failure. Cone beam computed tomography (CBCT) is the radiographic technique of choice if peri-implant dehiscence and fenestration defects are suspected. The higher radiation dose and the presence of beam hardening artifacts are the main drawbacks of CBCT imaging techniques. This study aims to evaluate the influence of low-dose cone beam computed tomography (LD-CBCT) and metal artifact reduction (MAR) tool on the assessment of peri-implant dehiscence and fenestration. Methodology Thirty titanium implants were inserted into bovine rib blocks. Twenty had standardized bone defects (10 with dehiscence and 10 with fenestration), while the remaining 10 were used as control group with no defects. Radiographic examinations held with high‐definition CBCT (HD-CBCT) and LD-CBCT with and without application of MAR tool. Images were assessed by four examiners for the presence or absence of peri-implant defects. The area under the area under the receiver operating characteristic (ROC) curve (AUC), sensitivity, specificity, and accuracy were calculated for all radiographic protocols. Results In the absence of MAR tool, there was no difference in AUC and diagnostic values between LD-CBCT and HD-CBCT for detection of both defects. When the MAR tool was applied, the AUC values, sensitivity, and accuracy were higher in HD-CBCT than in LD-CBCT for the detection of both defects, especially for the dehiscence, while specificity remained the same. Conclusion LD-CBCT can be used in the evaluation of peri-implant dehiscence and fenestration without any decrease in diagnostic accuracy. The application of MAR tool decrease the diagnostic ability of both defects, especially for the detection of dehiscence defects.
