Accelerated tooth movement evidence
- El Angbawi 2015 & Cochrane RV by Fleming 2015 low quality evidence of acceleration of tooth movement
How do teeth move quicker with the Regional Accelerated Phynomenon RAP
- Tissue remodelling
- Reduced dentistry of bone
- = increased bone turnover = increased tooth movement
Healing following Injury
- Granulation 7 days
- Callus modelling, remodel, 1-4 months, less time in soft tissues
- = 4 months to apply biomechanics, as density return to normal
Amount of injury = proportional to the amount of RAP effect
Experiment: Reduced bone dentistry in the direction of tooth movement increased tooth movement, finite analysis corticotomized bone Vs control
Results
- Corticotomy = Greater tooth movement
- M/F ratio lower for tooth movement
- Tooth movement lasts longer
Conclusion
- Corticomy should be in the direction of the tooth movement
Thanks Farooq, great summary!
Could you clarify this point in Carlalberta’s abstract for the IOC 2020:
A Finite Element analysis of tooth movement after corticotomy revealed that translation in corticotomized teeth occurs at a larger M/F ratio compared to normal bone turnover. In order to achieve this, a bigger moment needs to be inserted into the wire.
