Friction, binding and notching are the factors that contribute to resistance to sliding during orthodontic tooth movement. However, most attempts at reducing resistance aim only to reduce the archwire/ligature friction. In this study, a novel bracket with a unique design aimed to reduce all three components of resistance to sliding. Four types of brackets (passive and active self-ligating, traditionally ligated and the novel bracket, (n=5, each) were tested at 0, 2, 4, 6, and 8ᵒ of tip on a 0.019 x 0.025”archwire. The resistance to sliding values were recorded. At 0ᵒ, the passive self-ligating and novel bracket showed reduced resistance when compared to the traditionally ligated bracket (P< 0.05). At the other angles of tip, no differences were observed among the brackets. These data suggest that the novel bracket could potentially decrease the resistance to sliding during orthodontic treatment and further studies are indicated to test the improved bracket design.
