Introduction: In clinical orthodontics, the proper fit between the bracket slot and the archwire is of great importance. Geometry of the bracket slot plays a major role in efficient three−dimensional tooth movement during the orthodontic treatment. Materials and methodology: Damon Q second premolar brackets with 0.022 × 0.028−inch slot size were used in this study. The study consisted of 2 groups and each group had 10 samples group1 - as received Damon Q brackets, group2 - retrieved Damon Q brackets. These retrieved Damon Q brackets were used along with damon CuNiTi archwires in the oral cavity for a period of 32 weeks.

Results: Paired t test showed significant difference in the slot dimensions between the as received.. Read More»
