Abstract

Multiloop Edgewise Archwire(MEAW) is effective in relief the Curve of Spee in mandibular arch but up & down orthodontic elastics must be used with it. The purpose of this study was to analyse the effect of orthodontic elastics, like as up & down
elastics, Class II elastics, and Class III elastics, and the effect of L loop in Multioop Edgewise Archwire.
1. Intrusive force of MEAW in anterior teeth was reduced and uprighting force in premolars was increased by up & down elastics.
2. Uprighting force was significantly increased with Class III elastics in multiple L loop arch wire.
3. The force of Class II elastics made molars tip mesially and Curve of Spee deep.
