Effect of Brackets’ Types on the Amount of Movement and Rotation of Canine during Retraction: A Simulated In vitro Study
Journal Title: International Journal of Medical Research & Health Sciences (IJMRHS) - Year 2017, Vol 6, Issue 9
Abstract
Background: This in vitro study aimed to evaluate the effect of brackets’ materials on the distance moved by canine and rotation during sliding. Materials and methods: Extracted human maxillary canine tooth was used as facsimile to fabricate forty acrylic canine teeth with special mold. These teeth were bonded with 0.018 × 0.030-inch orthodontic brackets with different materials namely; stainless steel, titanium, ceramic and plastic one and impeded in wax in metal boxes. A 0.016 × 0.022 inch straight stainless steel archwire were ligated to the brackets with loose stainlesssteel ligature wire. Sliding of canine along the archwire was performed using nickel-titanium closed coil spring after wax softening at 50ºC. The distance moved by canine and the amount of rotation were assessed and compared among bracket types using one-way ANOVA and Tukey’s high signifcant difference tests. Results: Distance moved by canine was signifcantly more with stainless steel followed by titanium, plastic then ceramic one. On the other hand, canine rotated signifcantly more with ceramic brackets followed by plastic, titanium then stainless steel one. Conclusion: Canine moved more with stainless steel brackets with less rotation while it was just the opposite with ceramic brackets.
