Abstract

Abstract: Purpose: The aim of the study was to analyze the accuracy of measuring the cortical bone thickness using a combination of low‐ and high‐frequency ultrasound (US) compared with cone‐beam computed tomography (CBCT) and using stereomicroscopy as reference method. Material and Methods: Ten jawbone models were prepared using bovine ribs and porcine gingiva. A dental implant was placed in each model. All models were investigated by US, CBCT, and stereomicroscopy. The cortical bone thickness was measured directly above and 4 mm beside the implant with each method in different slices. Results: The median deviation of US measurements compared to the reference method was 0.23 mm. The CBCT method was slightly more accurate (median percent deviation of 9.2%) than the US method (10.3%). However, US measurements directly above the implant were more accurate than CBCT measurements with a median percent deviation of 10.5% for US vs. 11.8% for CBCT. Conclusion: Ultrasound showed a high potential to supplement CBCT for measurements of the cortical bone thickness.
