A plurality of brackets are fixedly mounted to various specific ones of a patient's teeth by adhesive or the like. Each bracket is provided with a slot for receiving an elongated arch wire in such a manner that a corrective force will be exerted against the patient's teeth through the brackets. Further, each bracket is provided with grooves for receiving ridges on auxiliary members to exert additional corrective forces to the teeth. A spring-type clamp or bail is used to hold a cap over the slot and to, in combination with the cap, hold the arch wire to within the slot as well as hold the auxiliaries in place on the bracket.
