Table 1 Mean values and standard deviations of each parameter

From: Comparison of implant placement accuracy in two different preoperative digital workflows: navigated vs. pilot-drill-guided surgery

Groups Total error at entry point (mean ± SD) Total error at apex (mean ± SD) Angular error (mean ± SD)
Pilot-drill guide 1.009 ± 0.415 mm 1.068 ± 0.384 mm 2.67 ± 1.58°
Navigation1 (marker tray in CBCT) 1.024 ± 0.446 mm 1.026 ± 0.383 mm 2.22 ± 1.54°
Navigation2 (3D-printed tray) 1.027 ± 0.455 mm 1.116 ± 0.530 mm 1.95 ± 1.35°
