Prof. David Bearn and Prof. Richard Cure
This presentation will use clinical examples to explore the biological benefit
and biomechanical approach when using passive self-ligating (PSL)
orthodontic fixed appliances.
The use of PSL to deliver a predictable light force allows the clinician to take a
new approach to the treatment of many malocclusions with a decreased
reliance on extractions.
After this presentation, you will:
· Understand how PSL appliance systems deliver low force and efficient
· Understand that a new approach to biomechanics is required to release the
potential of these systems
· Know about clinical and scientific evidence to support the use of PSL
