Figure 3

(A) Schematic diagram of the flowability experiment of solutions stored at each temperature. (B) Change in the viscosity as a function of shear force. (C) Average weight of 3D-printed aligner without supports according to the cleaning method used. (D) Cell viability of clear aligner model for each experimental group compared to the blank. The yellow line represents the minimum ISO standard (ISO 10993-5, 2009) criterion: a cell viability under 70% is cytotoxic. Different lowercase letters indicate significant differences in the average between groups (P < 0.05). NT, Not treated; IPA, Isopropyl alcohol; RT, Room temperature; HT, High temperature.
