Bone recovery after iatrogenic dehiscences and fenestrations
In this presentation, Dr. Huang will briefly review the two major theories of tooth movement - teeth roots move with bone (new bone forms around the tooth root as it is moved), vs teeth roots move through bone (the boundaries of the existing alveolar bone do not change, so roots can be moved outside the cortical bone). Obviously, it is better for patients and orthodontists if roots are able to move “with” bone. However, does this really happen? The popularity of non-extraction therapy, as well as the use of temporary anchorage devices, means we are moving teeth roots considerable distances, and both these techniques may increase the risk for dehiscences and fenestrations. Therefore, it is important to recognize these iatrogenic effects of orthodontic treatment, to minimize them where possible, and to facilitate bony recovery, if possible. Dr. Huang will present a new theory on how bony recovery of dehiscences and fenestrations might occur.
Aims and objectives
- Understand historical theories of bone movement
- Understand why iatrogenic dehiscences and fenestrations may be more common with current orthodontic techniques
- Learn about a new theory that predicts bony recovery when dehiscences and fenestration occur as a result of orthodontics
