ABSTRACT:
An orthodontic appliance system includes a plurality of connector appliances for rigidly connecting a force-supplying appliance to a patient's teeth to be positioned or stabilized. Each connector appliance includes a male connector piece rigidly attached to the force-supplying appliance and a female connector piece adapted for rigid attachment to a tooth to be positioned or stabilized. Each male connector piece is substantially wedge-shaped having a large base connected to the force-supplying appliance and a relatively narrow outer end. Each female connector piece includes a wedge-shaped receptacle generally corresponding in shape to the wedge shape of the male connector pieces, the receptacle being adapted to receive one of the male connector pieces in a fully inserted, connected position with the receptacle surfaces substantially abutting said wedge-shaped male connector. Each connector preferably also includes a locking device for locking the male and female pieces together in the connected position. The preferred locking means includes a spring loaded lever on the male connector piece with a projection that is adapted to be received in an aperture of the female connector piece when said connector pieces are in the connected position.
