Bone Morphometric Evaluation around Immediately Placed Implants Covered with Porcine-Derived Pericardium Membrane: An Experimental Study in Dogs

Figure 3

Merged optical micrograph depicting the control group, where the immediate implant placed at the mesial molar socket was not covered with a resorbable membrane prior to suturing. For this group, apical migration (arrows) occurred at both buccal (B) and lingual (L) aspects resulting in lower bone insertion levels along the length of the implant.
