“…The main results are presented below: The in vivo studies revealed a high precision of the peri-implant bone measurements, giving a high diagnostic value to CBCT in the detection of peri-implant bone loss, despite the presence of underestimation and overestimation of measurements with respect to histology [ 2 , 11 ]. CBCT demonstrated high precision in the diagnosis of peri-implant defects in almost all included studies, with a discrepancy in the real value of the defect averaging less than 1 mm [ 1 , 3 , 7 , 8 , 15 – 17 ]. The main limitation of CBCT is the presence of metallic artefacts, that is, image flaws unrelated to the digitized object, caused by metals such as dental implants and amalgam restorations, or to a lesser extent, by root canal filling materials in endodontic treatments [ 9 ].…”

The factors that determined the accuracy of CBCT in the measurement of bone defects in vitro were mainly the size of the defects and the presence of artefacts [ 1 , 5 , 8 , 9 , 15 ].…”

“…, who found a higher mean deviation from defect status for depth than for width measurements [ 8 ]. The explanation for this phenomenon seems to be that, in most cases, the deepest area of the defect was in the direct vicinity of the implant, and in these areas, more prominent artefacts were found than in others [ 13 ], as stated by Eskandarloo et al, who found that when a bone defect is adjacent to a dental implant, a radiolucent area is created, making it difficult to accurately detect the defect [ 17 ].…”

“…In the study of Schwindling et al, beam hardening artefacts made it difficult to define the depth of the circumferential defects, while the width measurements substantially agreed with the reference measurements [13], in line with Kamburoglu et al, who found a higher mean deviation from defect status for depth than for width measurements [8]. The explanation for this phenomenon seems to be that, in most cases, the deepest area of the defect was in the direct vicinity of the implant, and in these areas, more prominent artefacts were found than in others [13], as stated by Eskandarloo et al, who found that when a bone defect is adjacent to a dental implant, a radiolucent area is created, making it difficult to accurately detect the defect [17].…”

The objective of this work was to perform an integrative review of the inspection of peri-implant bone defects using cone beam computed tomography (CBCT). An electronic search was performed in the PubMed database using the following scientific terms: CBCT or Cone Beam computed tomography; dental implant; peri-implant; bone loss; defects. The survey identified 267 studies, of which 18 were considered relevant to this study. These studies provided important data taking into account the accuracy of cone beam computed tomography in the detection and measurement of peri-implant bone defects such as fenestrations, dehiscence and intraosseous circumferential defects. The effectiveness of CBCT in aiding in geometric bone calculations and in the diagnosis of peri-implant defects was influenced by factors such as artefacts, defect size, bone wall thickness, implant material, adjustment of acquisition parameters and observer experience. A not insignificant number of studies compared intraoral radiography to CBCT in the detection of peri-implant bone loss. CBCT was clearly superior to intraoral radiography in the detection of all peri-implant bone defects, except for defects located in the interproximal zone. In general, studies have shown that peri-implant bone measurements adjacent to the implant surface can be correctly determined, as well as the diagnosis of peri-implant bone defects with an average discrepancy of less than 1 mm from the actual measurement of the defect.

Background/purpose Information regarding agreements between periapical radiograph (PA) and cone beam computed tomography (CBCT) in detecting peri-implant defect is still scarce. The aim of this clinical study was to compare agreements between PA and CBCT in detecting peri-implant bone defect. Materials and methods This retrospective clinical study enrolled 32 patients with both PA and CBCT filmed right after implant placement. Four modalities were used for film reading: PA1 (original), PA2 (enhanced brightness/contrast), CBCT1 (selected axial and mesial-distal direction images) and CBCT2 (all data with software). 2 experienced and 2 inexperienced observers scored all films. Intra- and inter-observer agreements were estimated with Cohen's kappa coefficient. Categorized agreements were compared and differences among four modalities were calculated. Results Agreements of PA were better than CBCT when detecting peri-implant bone defects in inter-observer agreements (median kappa 0.471 vs. 0.192; p = 0.016). Moreover, agreements in experienced observers were better than inexperienced observers (median kappa 0.883 vs. 0.567; p < 0.001). There was significant difference among four modalities except for experienced observer 2 (p = 0.218). Conclusion Agreements of PA are better than CBCT when detecting peri-implant bone defects, especially for inter-observer agreements. Experienced observers are more consistent in assessment than inexperienced ones.
