### Removal Torque Measurement  
The four groups showed a different mean of RTv values, with statistical difference between them (\(p<0.05\)). The data are summarized in Table 3. Table 4 shows the Bonferroni test and \(p\)-values of the comparison between the groups in each time. The bar graph of Figure 9 showed the RTv values to compare the difference between the groups in the two times. \begin{table}
\begin{tabular}{c c c c} \hline
**9** & **Time 1** & **Time 2** & **Time 3** \\ \hline G1 & \(39.7\pm 3.54\) & \(40.9\pm 4.39\) & \(49.7\pm 4.89\) \\ G2 & \(38.6\pm 4.02\) & \(39.4\pm 4.12\) & \(46.9\pm 4.65\) \\ G3 & \(39.9\pm 3.46\) & \(49.1\pm 4.52\) & \(61.1\pm 4.72\) \\ G4 & \(39.9\pm 3.10\) & \(46.6\pm 4.58\) & \(58.8\pm 4.58\) \\ \hline \end{tabular}

Table 2: [PERSON]’s multiple comparison test to compare the ISQ values between the two times with statistically significant difference (at 15 and 30 days). Figure 8: Line graph showing the ISQ evolution on the different times in each group. Time 1 = immediately at the installation; Time 2 = 15 days after the installation; Time 3 = 30 days after the installation. In general, in the first time of the 15 days, a significant difference in the BIC% was observed between the group G1 X G3 and G2 X G3, with a higher value for the group G3. While in the second time (30 days) there were no statistical differences, only in the comparison between the same implant macrogeometry (G1 X G2 and G3 X G4). The data of measured values are presented in Table 5 and the distribution is shown in the graph attached. The statistical test analysis between groups is presented in Table 6.  
The bar graph in Figure 12 shows the BIC% values to compare the difference between the groups in the two time periods. The mean and standard deviation of BAFO% measured are showed in Table 7. The statistical differences between groups are presented in Table 8 and the bar graph in Figure 13 shows the data to visually compare the groups.
