- Subsidence under preload (Pdisp, n = 12) and its deflection (Pdefl, n = 12) and stiffness (Pstiff, n = 12), subsidence under cyclic loading (Cdisp, n = 10), total deflection (DEFL, n = 10), total stiffness (STIFF, n = 10), screw loosening (Cmov, n = 10), maximum progress of displacement (PDmax, n = 10). Stiffness is in N/mm, and all other values are in mm (Q25/Q75). Significantly different * (p < 0.05), ** (p < 0.01) between group 1 (non-augmented) and group 2 (augmented). The outliers were eliminated from cyclic analysis
