5. Study Description
Brief Summary
The study evaluates effectiveness of two types of fixed retainers in post orthodontic patients. Half of the subjects are randomly allocated Group 1 retainer (FRC) and other half is given Group 2 retainer (MSW) and followed for a period of one year.
Detailed Description
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.
