Abstract:
OBJECTIVETo analyze the mechanics of distalizating lower cuspid with the light-segmented archwire.
METHODSAn 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.
RESULTSUnder 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.
CONCLUSIONSThe light-segmented archwire would lead to bodily movement of the cuspid.
