Effect of thermoformed tray architecture on transfer accuracy of lingual brackets: A prospective clinical study
Fig 5
Violin and box plots of absolute bracket transfer deviations pooled across the total sample for each tray design.
BL1, bilayer tray (1.0-mm soft + 1.0-mm rigid); BL2, 2.0-mm soft + 1.0-mm rigid; BL3, 3.0-mm soft + 1.0-mm rigid; SR1 = single-layer 1.0-mm rigid tray.
