Values are presented as mean±standard deviation (mm3).
TAV: total augmented volume, NBV: new bone volume, RMV: residual material volume, BCP: biphasic calcium phosphate, UV: ultraviolet, M: group of defects covered with an BCP-supplemented UV-crosslinked collagen membrane without graft material, BG: group of defects filled with BCP particles without membrane coverage, BG+M: group of defects filled with BCP particles and covered with a BCP-supplemented UV-crosslinked collagen membrane in a conventional guided bone regeneration procedure.
a)Statistically significant difference compared to the control group; b)Statistically significant difference compared to the corresponding group at 2 weeks; c)Statistically significant difference compared to the BG group.
