ABSTRACT:
An improved orthodontic positioner provides a series of tiny suction devices on the tooth confronting walls of the positioner. These suction devices provide increased adherence of the positioner to the top, inner and outer tooth surfaces of the patient's teeth, and act to mechanically hold the teeth firmly together in their desired place within the positioner.
