Abstract:
Objective:To study the feasibility of rapid tooth movement by periodontal ligament distraction osteogenesis. Method: Periodontal ligament distraction osteogenesis technology was applied on the experimental side; traditional orthodontic tooth movement technology on the control side in 8 dogs. The treatment was countinued for 14 days. Tooth movement and alveolar bone remodeling were studied by in vivo measuring,roentgenogram, histology and immunohistochemistry 2,3,6 and 10 weeks after treatment respectively. Results:2 weeks after application of treatment tooth movement(mm) with periodontal ligament distraction osteogenesis and that with traditional orthodontic method was 3.49?0.57 and 1.06?0.32 (P0.05) respectively. Active osteogenesis was obsered on the tension loaded side, BMP expression on the experimental tension-loaded side was stronger than that in the control side (P
