Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
