Purpose: The aim of this study was to determine the linear dimensional accuracy of two separate Cone-Beam Computed Tomography (CBCT) machines using standardized models containing three dental implants.Method: This study was conducted at Saint Louis University Center for Advanced Dental Education (SLU CADE). Models were designed using 3D design software (Shapr3D) and printed using a personal grade 3D FDM printer (Anycubic Mega X). Four PLA models designed to incorporate three demonstration implants were printed. A total of 3 demonstration implants were placed in each of the 4 models printed. Cone-Beam Computed Tomography (CBCT) scans were completed using two different machines by the same manufacturer and model number (Carestream 9600 CS) at SLU CADE by a single investigator. A total of 72 CBCT scans were captured. All scans had the same 3D scan exposure parameters to include a field of view of O8x5cm 150 µm, Upper Jaw, Medium Adult, Carestream Metal Artifact Reduction (CSMAR) enabled, and used a standard resolution. Measurements of model-placed implants were made using a calibrated digital caliper (NEIKO Digital Caliper, 0.02mm accuracy) by a single Investigator. CBCT scans were measured using the software integrated measuring tool (Carestream; CS 3D Imaging) at the same locations as the caliper measurements and recorded. Statistical analysis was made to determine significance of the findings.Results: The mean of the differences between caliper and CBCT measurements of 0.03210 to 0.06558 indicate that caliper measurements were on average 0.05 mm larger than CBCT measurements (P < 0.0001). The lower and upper limits of agreement (0.03 and 0.07 mm), with the limits of agreement containing 95% of the differences for the sample of measurements used indicates that differences are less than ± 0.1 mm, which is far less than a 1 mm difference that would be considered clinically important. The mean of the measurement differences between the CBCT located in the periodontal clinic and that of the CBCT in the radiology department indicate that the CBCT in the periodontal clinic had measurements that were on average 0.12 mm (P < 0.0001) larger than the radiology machine. What are of more importance are the lower and upper limits of agreement (0.11 and 0.14 mm), with the limits of agreement containing 95% of the differences for the data. Differences are ± 0.14 mm, which is far less than a 1 mm difference that would be considered clinically important. Conclusion: Within the limitation of this study, it can be concluded that there is not a clinically important difference between measurements captured electronically from CBCT images and physical measurements made with a digital caliper. In addition, there is not a clinically important difference between the measurements taken between two CBCT machines of the same manufacturer and model.
