The Mechanical Properties and Biometrical Effect of 3D Preformed Titanium Membrane for Guided Bone Regeneration on Alveolar Bone Defect

Figure 7

The histological images of collagen membrane (CM) group. No membrane was observed in some specimens and the particulate bone graft materials were scattered to bone defect site in peri-implant. Amount of new bone tissues and osseointegration were less. NB, new bone; BGm, bone grafting material; I, implant (H&E stain; magnification 12.5x [left] and 40x [right]).
