Figure 2.

Representative image of a conventional mandibular radiograph (a) and μCT slices (b–f) within the middle of the distal root, 4th premolar extraction sockets after the six-week healing time. (b) μCT image of an extraction socket showing the region of interest analyzed for BV/TV and BMD. (c) Bovine xenograft particulate and collagen plug (X), (d) bone putty only (Bp), (e) xenograft particles sandwiched between layers of bone putty placed in the coronal and apical aspect, (Bp-X-Bp), and (f) a 3 : 1 mixture by weight of bone putty and xenograft particles, respectively (3Bp-X). Residual xenograft particles (appearing denser than the surround bone) can be seen in within the extraction sockets in panels (c), (e), and (f).
