Complete orthodontic load systems on teeth in a continuous full archwire: the role of triangular loop position.
BACKGROUND
A novel approach to characterizing orthodontic spring-generated force and moment systems has been developed. This method allows simultaneous measurement of all 6 force and moment components acting on a tooth.


METHODS
A continuous full archwire space-closure technique was simulated, and the complete force and moment systems acting on the teeth adjacent to the extraction space were measured.


CONCLUSIONS
The data showed that, in addition to the intended forces and moments, there are nontrivial activation-dependent interactions with the other load components, and these complex relationships are affected by the position of the triangular loop.
