We have known that orthodontic tooth movement not only causes root resorption but also alveolar bone loss, especially at the pressure side of anterior retraction or at the mesial side of molar protraction into an edentulous ridge. Alveolar bone loss might cause periodontal problems and less post-treatment stability due to less bony support. Several invasive and non-invasive techniques have been reported for accelerating orthodontic tooth movement. However, most of these techniques do not take into considerations of the risk of alveolar bone loss, except a few techniques such as the technique of periodontally accelerated osteogenic orthodontic procedures. The aim of this presentation is to present a technique of accelerating orthodontic tooth movement and at the same time decreasing alveolar bone loss in the procedures of anterior retraction and molar protraction into edentulous ridge by submucosal injection of platelet rich plasma at the target teeth. Both clinical cases and studies will be presented for illustrating the technique and scientific evidences.
Identify the pros and cons of various orthodontic techniques for accelerating orthodontic tooth movement.
Accelerate orthodontic tooth movement in anterior retraction and molar protraction into an edentulous ridge with a less risk of alveolar bone loss.
Familiarize themselves with the process of platelet rich plasma preparation for orthodontic purposes.
