Overview

In vitro study compares ultrasonography with cone-beam computed tomography for detecting peri-implant defects, indicating potential benefits and limitations.

Key Points

  • This study investigates the effectiveness of ultrasonography versus cone-beam computed tomography in identifying peri-implant defects.
  • Placed 72 implants in porcine rib bone models with various defect types.
  • Assessed defects with ultrasonography and cone-beam computed tomography.
  • Evaluated diagnostic accuracy measures including sensitivity, specificity, and correlation with direct measurements.
  • Ultrasonography showed > 95% diagnostic accuracy for defect type detection.
  • Sensitivity for detecting circumferential defects was 83.3%; positive predictive value for no-defect sites was 87.0%.
  • Cone-beam computed tomography achieved 100% accuracy in defect detection, outperforming ultrasonography in height measurement.
