ABSTRACT:
An orthodontic appliance for intraorally distalizing teeth without patient compliance, comprising a pair of small complementary permanent magnetic elements slidably mounted on a single common sectional wire in an arrangement to repel one another, and means for maximally reengaging the magnetic elements along the sectional wire. This arrangement avoids undesirable eccentric magnetic movement and maximizes control of the repelling horizontal magnetic forces.
