Design outcomes

Primary

Measure	Time frame
To compare the in vivo failure rates of both maxillary and mandibular fixed lingual retainers bonded with four light cured adhesive materials.Timepoint: 2 4 6 8 10 12 months	—

Secondary

Measure	Time frame
To evaluate the failure rate of lingual bonded retainer bonded with Enlight (ormco) adhesive. To evaulate the failure rate of lingual bonded retainer bonded with transbond XT (3M unitek) adhesive. To evaluate the failure rate of lingual bonded retainer bonded with Filtek Supreme (3M Espe) flowable composite.
