BACKGROUND: In free fibular flap surgery, the graft's low vertical height and tendency to resorb over time have been considered potential drawbacks. This study investigated (1) short- and long-term bone resorption in free fibular grafts; (2) resorption behavior of fibular grafts versus dentulous and edentulous autochthonous mandibular bone; and (3) factors that potentially influence long-term bone @entity194 , such as site of reconstruction, presence of osseointegrated dental implants, @entity1 age, and adjuvant radiation therapy. METHODS: Between 1992 and 2004, 113 @entity1 received free fibular grafts. Fifty-four of these @entity1 were examined retrospectively. Postoperative Panorex examinations assessed @entity604 per month. Standardized miniplate measurements served as a reference to prevent errors caused by projection on magnification. RESULTS: Follow-up ranged from 6 months to 12 years. According to Jewer's classification, the following defect types were found: L, 23 (42.6 percent); H, five (9.3 percent); C, two (3.7 percent); LC, 12 (22.2 percent); HC, nine (16.7 percent); and LCL, three (5.6 percent). Radiographic analysis revealed a monthly @entity194 of 0.04 +/- 0.08 mm (mean +/- SD) for fibular bone, 0.14 +/- 0.11 mm for dentulous mandibula, and 0.20 +/- 0.17 mm for edentulous mandibula. The difference in @entity604 between fibula and edentulous or dentulous bone was significant (Friedman's test and Wilcoxon paired-sample test, p < 0.0001 and p = 0.02, respectively). Investigated factors had no significant influence on bone resorption rate. CONCLUSIONS: Fibular grafts show short- and long-term stability. Their rate of @entity194 is significantly lower than that of edentulous or dentulous mandibular bone. Thus, implants can be inserted into this bone graft just as successfully as they are inserted into adjacent mandibular bone when the same bone height is present.
