Scanning of a Dental Implant with a High-Frequency Ultrasound Scanner: A Pilot Study

The purpose of this in vitro study was to assess the trueness a dental implant scanned using an intraoral high-frequency ultrasound prototype and compared with conventional optical scanners. An acrylic resin cast containing at position 11 fringe projection 3D sensor for use as reference dataset. same 10 times each group. Ultrasound scanning performed probe (42 MHz, aperture diameter 4 mm focus length 8 mm), images were reconstructed based on depth surface point echo. Optical scans laboratory scanner. A region interest consisting site segmented matched Trueness defined closeness between experimental data surface. Statistical analysis one-way ANOVA post-hoc tests significance level p = 0.05. No statistical difference found among evaluated mean deviation error 57.40 ± 17.44 µm scanner, 75.40 41.43 scanner 38.55 24.34 showed similar scanners digital impression.
