The in vitro study of complete-arch accuracy found the 3Shape TRIOS 3 to be significantly more precise than the two other scanners with the Medit i500 considered the least precise.
In terms of trueness, a significant difference between the scanners was also found. The 3Shape TRIOS 3 was determined the most accurate along with the Medit i500.
The ability of the scanners to reproduce the files of the reference scanner without overestimation or underestimation was also tested during the research. The TRIOS 3 and Emerald did not significantly either underestimate or overestimate the files of the gold standard. The Medit i500 produced files that significantly underestimated the reference scanner’s files.
The study’s conclusion stated: in terms of dentate complete-arch precision, 3Shape TRIOS 3 was the statistically more precise scanner. With the Medit i500 producing files that significantly underestimated the reference scanner files.
The comparison study was conducted by Dr. George Michelinakis, DDS, MSc, MPhil, Dr. Dimitrios Apostolakis, DDS, MSc, MSc, Dr. Andreas Tsagarakis, DDS, Mr. George Kourakis, BSc and Mr. Emmanuil Pavlakis, CDT.
