Effectiveness of Methods to Remove Residual Orthodontic Adhevsie

Not Applicable

Completed

• Conditions: Orthodontic Appliance Complication
• Interventions: Procedure: Recycling orthodontic brackets

• Registration Number: NCT05929391
• Lead Sponsor: University of Baghdad

Brief Summary

The aim of this study is to compare the clinical efficacy of different residual orthodontic adhesive removing methods for rebonding debonded metal attachments.

Detailed Description

1. To evaluate and compare the bond failure rates of rebonded brackets using two methods to remove the adhesive remnant and comparing them with contralateral teeth.

2. To evaluate and compare the bond failure rates of rebonded brackets between different quadrants and arches.

3. To evaluate and compare the bond failure rates of rebonded molar tubes using two methods to remove the adhesive remnant and comparing them with contralateral teeth.

4. To evaluate and compare the bond failure rates of rebonded molar tubes between different quadrants and arches.
