Accuracy of digital bitewing radiographs with and without applying horizontal tube shift in the diagnosis of residual excess cement around dental implants: An in vitro study.

Purpose: This study was designed to evaluate the diagnostic value of digital Bitewing (BW) radiographs with and without horizontal tube shift in detecting Residual excess cement (REC) on proximal non-proximal surfaces implant restorations. Material Methods: Eight mandibular models were fabricated two implants placed each side premolar first molar positions. Excess applied either or restorations intentionally during process crown cementation. BW applying acquired. Three maxillofacial radiologists asked determine presence location REC radiographs. Sensitivity specificity radiographic technique assessed according restoration surface that contained REC. Results: 100% for detection 41-18, 80% surfaces. Specificity 85.71%-100% 75-94. 12% areas. method generally greater than its sensitivity while areas, variables had quite similar values. Conclusion: Digital radiography is more useful Higher this bucco-lingual suggests reliability negative diagnoses
