Abstract
An orthodontic shape-memory alloy archwire for ligating to orthodontic appliances is heat treated, so that different sections of the archwire each exhibit a predetermined modulus of elasticity, and therefore impart a predetermined range of force when deflected. The distal ends of the archwire are further heat treated, or are treated with a dopant, to exhibit substantially diminished superelastic properties in comparison to the other sections of the archwire. The distal ends can therefore be deformed into shapes when ligated to orthodontic appliances to secure them to the appliances, and thus prevent them from slipping therethrough.
