Figure 4: Merged optical micrograph depicting the experimental group, where the immediate implant placed at the mesial molar socket was covered with a resorbable membrane prior to suturing. For this group, extensive apical migration (arrows) did not occur at both buccal (B) and lingual (L) aspects resulting in osseointegration at higher levels relative to the control side. The red and blue boxes are described in detail in Figure 5.
