ABSTRACT
To evaluate the accuracy of complete arch scanning with multiple implant
titanium scan bodies using laboratory scanners. A master model of an edentulous
maxillary arch with 6 implants was fabricated. Titanium scan bodies were inserted
into the model. Three laboratory scanners were used: D2000 (3Shape), Vinyl High
Resolution (Smart Optics), and inEos X5 (Dentsply Sirona). The master model was
consecutively scanned ten times using dental laboratory scanners (LS) without
detaching and repositioning the scan bodies. Linear and angular accuracy between
adjacent implants was measured using inspection software (Control X, Geomagic). The
accuracy of the complete arch scans was calculated. Implant regions were defined
as; parallel (R1: #24-26 and #16-14), angled (R2: #22-24 and #14-12), angled to
occlusal plane (R3: #12-22), and cross-arch (R4: #16-26). The effect of LS and implant
region on accuracy was compared using two-Way ANOVA (α=0.05). Significant greater
linear distortion was noted in R4 (61.2±17.9µm) compared to R1 (23.4±15.5µm) and
R2 (26±17.7µm) (p‹0.01). Greater linear distortions were noted in R4 with D2000
(0.07±0.016 degrees) and Vinyl High Resolution (0.067±0.02 degrees) than inEos
X5 (0.032±0.021 degrees) (p›0.05). Greater mean linear precisions were noted in
R1 (9±8µm) and R3 (9.3±8.3µm) than R4 (12.6±10.3µm) (p‹0.05). The highest
linear precision was noted in D2000 (7.2±7.6µm) (p‹0.05). The angular precision
of D2000 (0.02±0.015 degrees) was the highest (p‹0.01). The angular precision
of R4 (0.036±0.018 degrees) was the lowest (p‹0.01). This study revealed that the trueness was affected by the implant region and the precision was affected by both LS and implant region.
