Theses and Dissertations
The effect on shear bond strength of bracket movement after seating the brackets and before light curing has not been reported. The purpose of this study was to determine the effect of linear and rotational pre-cure bracket movement on the shear bond strength of orthodontic brackets. 100 extracted human maxillary premolars were divided into 5 groups of 20 teeth each. The control group was bonded with no pre-cure bracket movement, and test groups were bonded with pre-cure bracket movement of 2 mm, 4 mm, 45¢ª or 180¢ª. Debonding force was measured with an Instron universal testing machine. Results were analyzed …
