PERBEDAAN BESAR FORCE DARI BEBERAPA ELASTOMERIC CHAIN

DIFFERENT FORCE OF SOME ELASTOMERIC CHAINS

Abstract

Elastomerics is the one of orthodontic’s components which is used to move the teeth by archwire movement to the slot
bracket. Elastomeric products consist of ligature and chain. Elastomeric chain force depends on several factors such as
manufacturing process, duration and range of stretching. The obejective of this study was to know the effect of range and
duration of elastomeric stretching force. This study used elastomeric chain from three different manufacturers. Sample
was stretched at 20 percent, 30 percent and 40 percent. It was stored in artificial saliva that connected with thermostat at
37oC. Force was measured with correx. The result showed that there was no significant difference of force among three
different ranges. On the contrary duration of stretching elastomeric chain showed significant different force. In conclusion,
the longer stretching distance of these elastomeric chains showed bigger initial force and smaller force decay. The force
decay of these elastomeric chains decreased extremely on the first day and simultaneously decreasing on the next day.
