Abstract
The purpose of this study was to measure histomorphometric bone fill after different latency periods, rates of distraction, and duration of neutral fixation in the adult goat man-dible. In addition, the relationship between histomorphometric bone fill and clinical stability was investigated. Mandibular osteotomies in 18 female adult goat weighing 15-20 kg were distracted with modified semiburied distraction devices. Animal model divided into 3 groups; GO received plain tap water, G1; received fluoridated water at the level of 10 mg/kg body weight, G2; received fluoridated water at the level of 20 mg/kg body weight. The device was activated at a rate of 1mm/day for 10 consecutive days. Total distraction distance was 10 mm, period lasted for 25 days after end of the activation period and experimental period was 40 days.
