Elastomeric Force decay Self-ligation
2010/3/5
Objective: To compare elastomeric ligatures (EL) vs self-ligating (SL) brackets in terms of their effects on the unloading force of a 0.014-inch CuNiTi aligning wire.
Materials and Methods: By simu...

In this study the effects of prestressing, environmental acidity, oxygen content, and temperature on mechanical properties were measured for three polyurethane-based orthodontic elastomeric chains...
Orthodontic bone remodeling in relation to appliance decay
Orthodontic bone remodeling appliance decay
2009/1/12
This study examined alveolar bone turnover and orthodontic tooth movement after appliance decay. One group of rats (N=54) received orthodontic force (40 g initial activation) while the other (N=36...
Effect of appliance reactivation after decay of initial activation on osteoclasts, tooth movement, and root resorption
Orthodontic tooth movement Osteoclasts Histomorphometry Alveolar bone Root resorption
