• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 90 (estimated)
• Sponsor: Cairo University · Academic / Other
• Sex: All
• Age: —
• Healthy volunteers: Accepted

Summary

The study will be performed on human subjects with finished orthodontic treatment to see the failure rate(detachment) of fixed lingual retainer between two types of light cure resin composite

Detailed description

The study consists of two groups, the intervention involve performing bonding of fixed lingual retainer with light cured composite Transbond LR which is manufactured specific for the fixed lingual retainer while the control group involve bonding of fixed lingual retainer by light cured composite Transbond XT with follow up every month for 6 month to see the failure rate(detachment) between the two types of composite

Conditions

• Orthodontic Retainer

Interventions

Type	Name	Description
OTHER	Transbond LR	cleaning the lingual surface using oil free pumice then apply acid etch 35% phosphoric acid for 20 second then rinse then Transbond LR will be applied directly on the fixed retainer and lingual surface of the teeth then light cured.
OTHER	Transbond XT	cleaning the lingual surface using oil free pumice then apply acid etch 35% phosphoric acid for 20 second then rinse then Transbond XT will be applied directly on the fixed retainer and lingual surface of the teeth then light cured.
