CBCT devices offer a scanning protocol mode with a partial rotation arc of 180o, followed by a 360o image reconstruction through algorithms. This scan mode is associated with a low number of basis images and subsequent reduced image quality.
However, it does not influence the appearance of artefacts, and it offers a reliable alternative for assessing peri-implant bone.
Although the appearance of dental implant artefacts is well documented in literature, metal artefacts are usually determined by grey values or contrast-noise-ratio, but fewer studies have reported the influence of artefacts on diagnostic image quality.
