A 12-month clinical study comparing four Glass Ionomer Cements for the cementation of orthodontic molar bands

Four different glass ionomer cements were evaluated in vivo as luting agents for orthodontic mohu bands. A sample of 199 patients with full fixed appliances (Begg Light Wire) were monitored over a period of 12 months during active treatment for loose molar bands. Failures for each edment were: Fuji I, 2-5 percent, Fuji II, 4-5 percent, Ketac- Cem, 4-0 percent and Hy-Bond Luting, 3-0 percent. Chi squared tests showed no statistical difference in failure rates for each cement.
