Table 2.
Membrane group (Mb, n = 8) and non-membrane group (non-Mb, n = 7). Tissues in contact with the implant surface expressed in percentages (%) for the whole implant surface and for the apical and coronal regions of the implant. SD, standard deviation; 25%, first percentile; 75%, third percentile; # = p < 0.05 between apical and coronal regions.
