Comparative Assessment of Failure Rate of Fixed Lingual Retainer Between Two Types of Light Cured Resin Composite

Study Overview
=================
Brief 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

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Transbond LR<br>in finished orthodontic cases a light cured resin composite (Transbond LR) will be added on fixed lingual retainer to see the failure rate (detachment) with follow up every month for 6 months | Other: Transbond LR<br>* 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.<br>* Other names: 3m brand;|
| Active Comparator: Transbond XT<br>in finished orthodontic cases a light cured resin composite (Transbond XT) will be added on fixed lingual retainer to see the failure rate (detachment) with follow up every month for 6 months | Other: Transbond XT<br>* 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.<br>* Other names: 3m brand;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Failure rate( detachment rate) of fixed lingual retainer | measured by inspection of any detachment partial or complete of the fixed lingual retainer | the patient will be inspected after applying the fixed retainer every month for 6 months |
