Deviations (mean ± standard deviation (SD) [µm]) of the linear distances (D1_2, D1_3, D1_4, D2_3, D2_4, D3_4) of six impression techniques (CS = CS 3800, IT = iTero Element 5D, ME = Medit i700, PS = Primescan, TR = Trios 4, CVI = conventional impression) for Group A (young fully dentate) and statistical analysis for trueness (upper right part) and precision (lower left part, presented in bold type) according to ISO 5725 [6].
