Abstract

Objective: To evaluate of dimensional accuracy of the slot size in passive self-ligating brackets from three different orthodontic companies.Material and method: Total of 90 upper right central incisor self-ligating brackets, 30 each of 0.022 inch slot from three commercially available manufactures (American orthodontics, Forestadent, Damon Q) were divided into 3 groups of 30 brackets each. Stereomicroscope was used, coupled to a computer with a Charge Coupled Device (CCD) camera to obtain the images. After insertion, the brackets were adjusted with a segment of 0.016” x 0.022” stainless steel wire. The images obtained by the microscope were analyzed in the Image analysis software (MVIG 2005) by a laboratory technician as instructed by the authors. Images (90) captured for slot dimension measurement had total magnifications 15X for all samples size.Results: The result showed that the mean values for slot width at base of brackets were: American orthodontic (0.02384 inch), Demon Q (0.0245667 inch), and Forestadent (0.0238267 inch). The mean value of group 1 and group 2 had variation as compared to group 3 as specified by the manufacturer.The mean values slot width at top of brackets was: American orthodontic (0.0249133 inch), Demon Q (0.0250067 inch), and Forestadent (0.0242533 inch). The mean value of group 1 and group 2 had more variation as compared to group 3 as specified by the manufacturer.Conclusion:The resultsobtained conclude that the width of the slot was either more or less than specified by the company and the width of the bracket slot at top and the base was also not equal.
