ABSTRACT:
A kit is provided containing magnetic modules, attachment wire and a set of gages. The modules are rectangular prismatic formed from a cobalt-samarium alloy, covered with a chlorinated poly-p-xylene coating or stainless steel and jacketed in stainless steel with orthogonally related passages on opposite sides having rectangular cross-sections for receiving with a snug fit the rectangular cross-section attachment wire formed by welding together two lengths of standard edgewise wire. The gages provide means for spacing the modules when the latter are incorporated in an appliance.
Appliances are illustrated for accomplishing a variety of orthodontic procedures. The construction of the modules and attachment wire permits construction of appliances where the modules are constrained in the jaw closed in centric condition to translate parallel to their respective pole faces in a "sliding" fashion.
