Abstract
A mandibular and maxillary arch expansion apparatus having a first and second forward orthodontic bands and first and second rear orthodontic bands. The respective forward and rear orthodontic bands are interconnected by an expansion sheath element. The two forward bands are connected by a substantially straight, solid rod. The expansion sheaths exert lengthening forces while the solid rod resists lateral or widening forces. Also provided is a maxillary apparatus connected to a mandibular apparatus by a telescoping contraction connector. The device is positioned to exert adjustable contracting pressure for the correction of Class II malocclusions or overbite. Also provided is an arch expansion apparatus with a centrally disposed expansion element having two forward connector wires extending outwardly therefrom and two rearward connector wires extending outwardly. Each connector wire has an orthodontic band on the terminal end. The expansion element can be actuated so as to elongate the expansion element so as to exert arch expansion pressure.
