Abstract

Aim of the study: The current study was conducted to determine the accuracy of QuickScan imaging protocols of iCAT Flx CBCT machine in detection and measuring crestal bone defects around dental implants.
Materials and Methods: 20 simulated peri-implant crestal bone defects were created in bovine ribs bone models then were scanned by iCAT FLX CBCT machine with HD Scan 0.25 mm voxel, QuickScan 0.25mm voxel, and QuickScan + 0.3mm voxel sizes. All scans were imported in on-demand 3D App software and produced linear measurements were compared to true measurements done directly with digital caliper on bone models.
Results: All imaging protocols of CBCT showed no statistical significance in detection of shallow peri-implant bone defects while the QuickScan + imaging protocol showed less accuracy in measuring the depth of defects.
Conclusion: QuickScan + can be used as a low dose periodic follow up imaging utility for postoperative implant surgery for detection of any small bone changes but if more details are needed QuickScan technique is required.
