Abstract:

BACKGROUND: To accelerate orthodontic movement speed and shorten treatment course is the focus in recent studies. Some researchers propose the concept of peridental ligament distraction osteogenesis, which is one special application type of distraction osteogenesis. This method has been used in clinical orthodontic treatment and can accelerate canine teeth movement, significantly shorten treatment duration, and improve correction efficacy. It provides a novel approach to shorten long treatment course.
OBJECTIVE: To establish three-dimensional finite element model (3-D FEM) with better similarity of rapid canine tooth movement in periodontal ligament distraction.
METHODS: By using scanning of spiral CT with 64 rows, the sectional image data in DICOM of TMJ, mandible and lower tooth were acquired. With the help of Mimics, Geomagic Studio 8.0, Unigraphics NX and Ansys 11.0 software, the 3-D FEM of rapid canine tooth movement in periodontal ligament distraction, including TMJ, mandible, lower tooth and periodontal ligament was established.
RESULTS AND CONCLUSION: A 3-D FEM of rapid canine tooth movement in periodontal ligament distraction was established, which consisted of 39 060 elements and 76 103 nodes. Furthermore, we could add or delete the framework according to different research demands.
