Detection of Crestal Radiolucencies Around Dental Implants: An In Vitro Experimental Study

Effect of field of view in the detection of chemically created peri-implant bone defects in bovine ribs using cone beam computed tomography: an in vitro study

“…Previous studies have tested the accuracy of CBCT in detecting peri-implant bone defects 6,7,[12][13][14][15][16] ; however, the size and shape of the defects and the viewing conditions used in these studies failed to mimic actual clinical situations. Furthermore, only one of them compared the detectability of different CBCT fields of view (FOVs) for peri-implant bone defects 12 and found no difference between the different settings.…”

Accuracy of CBCT images in the assessment of buccal marginal alveolar peri-implant defects: effect of field of view

“…They found similar intra-and interobserver agreement levels and lower detection rates for multislice CT with comparable rates for all other modalities. Unlike the Sirin et al 18 study, we did not assess decision-making speed or image quality of different radiographic modalities as these variables are relatively subjective and observer dependent. In addition, observers in the above mentioned study 18 assessed circumferential defects, whereas we investigated buccal defects only, which are clinically more difficult to detect.…”

“…[15][16][17][18] However, unlike intraoral radiography, if metallic objects such as amalgam or titanium implants are present in the CBCT scan, two artefacts can be produced degrading image quality. Streak artefacts due to the presence of scatter radiation as linear hyperdensities radiating from the metallic object might extend to the entire width of the field, affecting even the visualization of areas on the opposite side of the jaw.…”

Clinical efficacy of cross-sectional imaging compared with panoramic imaging and virtual 3D models for the assessment of dental implant placement.

“…However, often practitioner clinical success is often defined as patient satisfaction, rather than with esthetic, functional or other quantitative metrics. Another research suggests that direct digital radiography and periapical radiography have accurate and faster diagnostic ability as compared to CBCT, which has "lower image quality and slower decision making ability" when detecting crestal radiolucency around dental implants (Sirin, et al, 2012).…”

“…The restorative space and alveolar ridge measurements were calculated in both panoramic and cross-sectional imaging according to standardized reproducible criteria Fig. 6 (Sirin, et al, 2012, Pittayapat, et al, 2013. A virtual dental implant was placed on the reformatted panoramic image and virtual models, simulating the diagnostic implant planning procedure most often used by practitioners without access to cross-sectional imaging.…”
