Comparison of two distraction rate of periosteal distraction osteogenesis: An experimental study in the rabbits
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 3
Abstract
The aim of the present study was to evaluate the influence of two distraction rate of periosteal distraction on bone. A custom-made dynamic periosteal distraction device consisted of titanium perforated plate fixed to the lateral surface of the mandible in 12 adult rabbits. After an initial healing period of 7 days, the device was activated at a rate of 0.25 mm every 12 hours for 6 days in 6 animals (group 1), and at rate 0.5mm every 12 hours for 3 days in 6 animals (group 2). The animals were sacrificed after of 8 weeks of consolidation period. The specimens were then fixed, decalcified, and stained with hematoxylin and eosin. The histological evaluation showed a various amount of new bone formation with large spaces between bone trabeculae in the two groups. Although, the amount of new bone was greater in the group 2. The results of the present study showed that reducing the distraction rate increases bone formation.
