Comparison Between Shear Bond Strength of Different Commercial Metal Bracket Brands: an in Vitro Study

NCT05812456 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

No results posted yet for this study

Summary

some orthodontic brands are more expensive than others, one of the primary outcomes of this study is to know if is it worth using expensive brands? will it provide better quality treatment, in particular, bond strength? The treatment duration is long therefore it is expensive, either for the orthodontist and/or the patient.

This study will be comparing the bond strength of different commercial brands of stainless steel brackets.

Conditions

  • Orthodontic Appliance Complication
  • Shear Strength

Interventions

Estimation of Shear Bond Strength

Measuring shear bond strength between the different bracket brands and the enamel will be estimated by aiming the edge of the blade of the universal testing machine at bracket-enamel interface. The force required to debond each bracket will be registered in Newtons (N), and converted to Megapascals by dividing the force registered in newtons on each bracket base area (mm2). After bond failure, the brackets and the enamel surfaces will be examined and assessed for the amount of adhesive remaining on the bracket bases by using digital microscope at 35x magnification. this will identify the site of bond failure.
