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

Figure 4

Cross-sectional radiographic images demonstrating variations both between and within the groups: (a) BMP group with pins, (b) nonBMP group with pins, (c) BMP group without pins, (d) nonBMP group without pins, and (e) control group. In the BMP and nonBMP groups, the shape of the augmented region appeared to be predominantly influenced by the use of pins.
