Figure 4

Parameters measured in the histologic specimens. Red box, the area of interest (AOI was 1 mm horizontally and vertically a range from the horizontal crest of the first thread of the implant to the horizontal crest of the third thread); blue arrow, the horizontal crest of the first thread of the implant (FT); yellow arrow, the most upper point of the new bone (NB); white arrow, the most upper point of the osseointegration site (OI); green arrow, the most upper point of the old bone of AOI (OB).
