Figure 4. Representative fluorescent (a,c,e) and polarized (b,d,f) microscopic photographs. Three-week HC in the maxilla (a,b), 12-week HC in the mandible (c,d), and three-week FA in the mandible (e,f). In three-week groups, intense fluorescent labels and woven bone (W) formation were observed adjacent to the implant (I), whereas in 12-week HC and three-week FA, fewer labels and less lamellar (L) bone formation were predominantly observed. Bars indicate 0.5 mm.
