Ambient light illuminance for Intraoral scanner may maximize scanning accuracy: Study
It is essential to optimize ambient light illuminance for each intraoral scanner (IOS) to maximize scanning accuracy, according to a recent study in the Journal of Dentistry.
The purpose of this in vitro study was to evaluate the effect of ambient light illuminance on the accuracy and scanning time of different intraoral scanners (IOSs) in complete-arch implant scans. Seven IOSs (TRIOS 3, Primescan, Element 5D, i700, i500, CS3700, and CS3600) at 5 ambient lighting illuminances (100, 500, 1000, 5000, and 10 000 lux) were evaluated. An edentulous cast with 4 implants was selected as the master model. An implant scan body was tightened on each implant analog. The cast was digitized by using a laboratory scanner to obtain a reference standard tessellation language (STL) file, and 10 scans with each IOS were recorded. Scanning time was recorded by using a digital chronograph. Intraoral scan deviations were calculated by using a reverse engineering software program (Geomagic Control X). Kruskal-Wallis and pairwise comparison tests were used to analyze the data (α=.05).
The results of the study are:
• The trueness and precision values obtained for each IOS tested were significantly different under the varying lighting conditions assessed.
• TRIOS 3 (34.0 ±3.3 µm trueness; 24.5 ±14.9 µm precision), Element 5D (34.5 ±7.1 µm trueness; 25.9 ±7.6 µm precision), and CS3700 (34.9. ±13.0 µm trueness; 34.6 ±19.2 µm precision) performed better under 100 lux illumination, CS3600 (69.5 ±24.0 µm trueness; 36.6 ± 20.1 µm precision) at 500 lux; i500 (36.2 ±5.1 µm trueness; 21.4 ± 6.8 µm precision) at 1000 lux; i700 (34.8 ±2.2 µm trueness; 15.4 ±5.0 µm precision) at 5000 lux, and Primescan (37.4 ±37.3 µm trueness; 26.2 ± 26.2 µm precision) at 10000 lux.
• Additionally, the scanning time was different under different illuminance for each IOS.
• The fastest IOS in all light conditions was Primescan, with significant differences with all the groups (P<.01), followed by TRIOS 3 in all groups except under 100 lux illumination, where i700 was the second fastest.
Thus, ambient light influenced the accuracy and scanning time of IOSs assessed; however, the effect was not the same for all devices. It is necessary to optimize ambient light illuminance for each IOS to maximize scanning accuracy.
