ABSTRACT:
A method for treatment of orthodontic wire located in a patient's mouth, the wire containing a titanium alloy having either an alpha/beta crystalline structure or a near alpha crystalline structure. The alloy preferably comprises greater than 5% alpha stabilizing components and is maintained below its beta transus. The wire is exposed to an aqueous hydrogen contributing substance over a period of time in the patient's mouth so as to progressively harden or stiffen the wire over that period of time to maintain or increase the force applied by the wire on teeth of the patient.
