Description
AOA Distalizer Lock Nut Screw, found in products listed as: Distal Jet, Spring Jet, Mesial Jet, and Uprighter Jet. Removable functional orthodontic appliances that are to modify the growth of the jaws in a prescribed growth pattern.
The Lock Nut component of the Jet appliances may be missing the screw collar, which serves as a mechanical stop to prevent over-tightening in appliance assemby. Without this collar, an over-tightened lock nut may stop the piston assembly from moving freely, subsequently preventing intended movement of the teeth.
