Akurasi ukuran tinggi slot bracket dan diameter kawat ortodonti dari beberapa produkAccuracy of bracket slot heights and various orthodontic wire diameters

Introduction: Different orthodontic brackets and wire products are available in the market; thus, orthodontists must care-fully choose the products used. The bracket slot height and the wire diameter on the package label may differ from the ac-tual size, affecting tooth movement during orthodontic treatment. The purpose of the study was to analyse the accuracy of the bracket slots height and the wire diameter of 3M/Unitek, Ormco, and Dentaurum brands. Methods: This research was analytical laboratory observations with a cross-sectional design. The research sample consisted of 30 maxillary incisor brackets with 0.022-inch slots and 45 wires measuring 0.019 x 0.025 inches of 3M/Unitek, Ormco, and Dentaurum brands. The measurement of bracket slot height and orthodontic wire diameter was conducted using a Discovery V12 Stereoscope Microscope and related software. Results: The mean value of Ormco slot height measurement results was 0.488 mm, 3M/Unitek was 0.491 mm, and Dentaurum was 0.538 mm. The standard deviation of the mean slot bracket height was 0.001 inches. The average value of wire diameter of Ormco in the form of wire height was 0.413 mm, and the wire width was 0.496 mm; the wire height of 3M/Unitek was 0.413 mm, and the wire width was 0.500 mm; the wire height of Dentaurum was 0.419 mm, and the wire width was 0.510 mm. Conclusions: There is a difference in the mean size of the bracket slot height and the orthodontic wire diameter of 3M/Unitek, Ormco, and Dentaurum brands, between the measurement results and the product knowledge.
