Figure 8

Subgroup analyses for the effects of augmentation on marginal bone loss, with baseline at implant placement, in maxilla (a), mandible (b) and both jaws (c) at 1-year. Subgroup analyses of maxilla/mandible on MBL (from IP) at 3-years follow-up (d). Negative value in difference in means indicates more MBL in the longer implant group.
