Trueness and Precision of Three-Dimensional Digitizing Intraoral Devices

Figure 5

Bull’s eyes chart showing the deviations between the mean of repeated measurements for all implant axes of all scanner devices and the true values (trueness) and the deviations between the results of independent measurements obtained within one scanner device under specific condition (precision). This chart is color-coded; each color represents the implant number (1–5) in the master model.  μm = micron.
