The long consolidation period of distraction osteogenesis (DO) may lead to complications such as pain, infection, fracture, scar formation, malunion and delayed union. The aim of this study was to evaluate the effect of systemic Vitamin E application during mandibular DO on new bone regeneration in a rabbit model. 16 adult male 8 months old New Zealand rabbits underwent mandibular lengthening with a distractor for the study. After the latency period of 5 days, the distractor was activated at a rate of 0.5 mm/12 hours for 7 days. Experimental animals received 200 mg/kg injections of α-tocopherol intraperitoneally for 7 days starting with the operation. After the consolidation period of 30 days, rabbits were sacrificed. Lengthened mandibles were obtained and subjected to dual-energy X-ray absorptiometry (DXA), radiologic and histomorphometric analysis. Statistically, bone mineral density and bone mineral content values were found to be significantly higher in the experimental group than the control group during DXA analysis. Rabbits in the experimental group had statistically higher scores in terms of osteoblast, osteoclast, vessel numbers and newly formed bone area than the control group. Results of the present study showed that systemic Vitamin E application during DO may stimulate new bone formation in rabbits and thus results in shortened treatment time.
