Presentation Abstract
THE SIX GEOMETRIES, DO THEY ALWAYS APPLY IN STATICALLY INDETERMINATE ALIGNMENT?
When inserting an archwire into a set of two or more brackets, a statically indeterminate force system is created. Burstone’s Six Geometries provide a valuable approach for defining the relative force system, but this theory is based on the assumption of linear beam behavior. However, when dealing with a non-linear alloy or certain wire configurations, the resulting force system may deviate from what is predicted by the six geometries concept. Specifically, the dissociation between force and moment may vary.
In this presentation, we will explore various scenarios where the force system delivered by statically indeterminate mechanics cannot be accurately described by the six geometries concept. We will examine how these systems differ from the conventional analysis based on this theory and highlight the conditions under which discrepancies arise.
