Bone Regeneration of Peri-Implant Defects Using a Collagen Membrane as a Carrier for Recombinant Human Bone Morphogenetic Protein-2

Figure 2

Clinical photographs of the bone augmentation procedure applied to peri-implant dehiscence defects: (a) buccal and (b) occlusal views after implant placement and (c) GBR treatment performed on dehiscence defects according to group assignment. The control group was placed at the center implant site, and the BMP and nonBMP groups were randomly allocated to the mesial and distal implant sites.
