Three-dimensional finite element analysis of distalization of lower cuspid with light-segmented archwire technique / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the mechanics of distalizating lower cuspid with the light-segmented archwire.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>The light-segmented archwire would lead to bodily movement of the cuspid.</p>
