54 subjects were recruited and divided into two groups by random allocation. Consents were obtained . Group 1 received fiber reinforced composite retainer and group 2 received multistranded stainless steel wire retainer. The patients were recalled at every three months interval for a period of 12 months. They were evaluated for number of fractures, failure pattern based on adhesive remnant index and relapse tendency by measuring little's irregularity index.
