About this study

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

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients need metal fixed orthodontic appliance treatment;
  • Complete set of permanent dentition with fully erupted teeth on both arches;
  • Intact teeth and mainly their buccal surfaces are free from caries, fillings, or gingival hyperplasia;
  • No occlusal interferences that can affect the ideal position of attachments, especially in the lower arch.

Exclusion criteria

  • patients have crown, missing teeth, or craniofacial anomalies.
  • patients have congenital enamel defects specially their buccal surface.

Treatment and study plan

Recycling orthodontic brackets

Procedure

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.

Primary outcomes

  1. The number of bonding failures will be compared using the chi-square test.

    Time frame: baselines

    evaluate and compare the bond failure rates. different quadrants and arches.To evaluate and compare the bond failure rates of rebonded attachments(brackets and molar tubes)using two methods (Tungsten carbide bur and sandblasting)) to remove the adhesive remnant and comparing them with contralateral teeth.

Secondary outcomes

  1. The bonding failure between each quadrant will be compared by one way ANOVA.

    Time frame: bsaelines

    evaluate and compare the bond failure rates. different quadrants and arches.
