Tab. 2.

Co, Cr, Mn, and Ni release from orthodontic bands immersed in an artificial saliva solution for 44 days (total release and release profile). Metal release from 4 bands (22 different products). Total metal release is expressed as  the mean value ± standard uncertainty. Metal release profiles were grouped into three categories: “constant release” (α), “intermediate” (β), “saturation” (γ). Note: different custom attachments were welded onto the bands

Tab. 2 Co-, Cr-, Mn- und Ni-Freisetzung aus kieferorthopädischen Bändern, die 44 Tage in künstlicher Speichellösung gelagert waren (Gesamtfreisetzung und Verlaufsprofil). Metallfreisetzung aus 4 Bändern (22 unterschiedliche Produkte). Die Freisetzung von Metallen insgesamt ist angegeben als Durchschnittswert ± Standardabweichung, die Freisetzungsprofile wurden in 3 Kategorien eingeteilt: “konstante Freisetzung” (α), “intermediär” (β), “Sättigung” (γ). Man beachte, dass auf den Bändern unterschiedliche Attachments aufgebracht waren
