Clinical Trial Summary

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

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.

Intervention

Procedure:
• Recycling orthodontic brackets
T0: The adhesive removal will be performed by high-speed hand piece with tungsten carbide bur. the bur will be changed every five attachments. T1: Control group of T0. T2: The adhesive removal will be performed by sandblasting via Micro-etcher. T3: Control group of T2.
