| Abstract: | Periodontal ligament distraction（PDLD） and dentoalveolar distraction（DAD） are specific technologies used for the acceleration of orthodontic tooth movement. In this article, the author attempts to compare PDLD and DAD in terms of operation, foundation, distraction process, characteristics of tooth movement, movement of anchorage and tooth in new bone, change in periodontal histopathology, and potential risk during the process. |
