SPACE CLOSURE IN THE AGE OF “ VARIABLE
MODULUS ” MECHANICS
Ormco helped develop the
original Beta Titanium wire more than two decades ago. Over the years, Ormco
refined the TMA manufacturing process to a science in order to deliver the TMA
brand of Beta Titanium wire that remains the industry standard for consistency
With half the force but twice
the working range of stainless steel1 , TMA has indications for all stages of
treatment. Because of its intermediate stiffness between stainless steel and
the nickel-titanium memory alloys, it is especially beneficial as a main
working archwire. TMA has good flexibility and springback characteristics along
with predictable forces for consistent control.
• Initial Stage – TMA is recommended for tooth alignment, space
closure and Curve of Spee. Ormco offers preformed Reverse Curve TMA and Reverse
Curve TMA with “T” Loops.
• Intermediate Stage – TMA is recommended for early torque control
with moderate forces. TMA also provides complete manipulation of the wire for
dimensional control. Indications include use as an ideal retraction arch while
exerting constant moderate forces over a longer period of time.
Final Stage – TMA is used as a detailing wire with moderate force.
