[Three-dimensional finite element analysis of distalization of lower cuspid with light-segmented archwire technique].
OBJECTIVE
To analyze the mechanics of distalizating lower cuspid with the light-segmented archwire.


METHODS
An experiment, which imitated the loading of distalizating lower cuspid with the light-segmented archwire, was performed on the three-dimensional finite element method model of lower cuspid. The patterns of stress distribution of the root were analyzed.


RESULTS
Under the loading of the light-segmented archwire, the lower cuspid root presented an even pressing force distribution on the distal and lingual side and an even stretching force distribution on the mesial and buccal side.


CONCLUSIONS
The light-segmented archwire would lead to bodily movement of the cuspid.
