Table 3 Comparison of deviations and angulations between short sleeves (4 mm) and long sleeves (10 mm) for the pilot-drill guided implant insertion. The means, their standard deviations (SD), medians, minima and maxima are shown. The p-values are resulting from a pair-wise comparison. P-values for statistically significant differences are marked in bold font
